You may obtain a copy of + the License at http://www.mozilla.org/MPL/ + + + How this code works: + + Processing starts when the caller generates a new recurrence + iterator via icalrecur_iterator_new(). This routine copies the + recurrence rule into the iterator, extracts things like start and + end dates. Then, it checks if the rule is legal, using some logic + from RFC2445 and some logic that probably should be in RFC2445. + + Then, icalrecur_iterator_new() re-writes some of the BY* + arrays. This involves ( via a call to setup_defaults() ) : + + 1) For BY rule parts with no data ( ie BYSECOND was not specified ) + copy the corresponding time part from DTSTART into the BY array. ( + So impl->by_ptrs[BY_SECOND] will then have one element if is + originally had none ) This only happens if the BY* rule part data + would expand the number of occurrences in the occurrence set. This + lets the code ignore DTSTART later on and still use it to get the + time parts that were not specified in any other way. + + 2) For the by rule part that are not the same interval as the + frequency -- for HOURLY anything but BYHOUR, for instance -- copy the + first data element from the rule part into the first occurrence. For + example, for "INTERVAL=MONTHLY and BYHOUR=10,30", initialize the + first time to be returned to have an hour of 10. + + Finally, for INTERVAL=YEARLY, the routine expands the rule to get + all of the days specified in the rule. The code will do this for + each new year, and this is the first expansion. This is a special + case for the yearly interval; no other frequency gets expanded this + way. The yearly interval is the most complex, so some special + processing is required. + + After creating a new iterator, the caller will make successive calls + to icalrecur_iterator_next() to get the next time specified by the + rule. The main part of this routine is a switch on the frequency of + the rule. Each different frequency is handled by a different + routine. + + For example, next_hour handles the case of INTERVAL=HOURLY, and it + is called by other routines to get the next hour. First, the routine + tries to get the next minute part of a time with a call to + next_minute(). If next_minute() returns 1, it has reached the end of + its data, usually the last element of the BYMINUTE array. Then, if + there is data in the BYHOUR array, the routine changes the hour to + the next one in the array. If INTERVAL=HOURLY, the routine advances + the hour by the interval. + + If the routine used the last hour in the BYHOUR array, and the + INTERVAL=HOURLY, then the routine calls increment_monthday() to set + the next month day. The increment_* routines may call higher routine + to increment the month or year also. + + The code for INTERVAL=DAILY is handled by next_day(). First, the + routine tries to get the next hour part of a time with a call to + next_hour. If next_hour() returns 1, it has reached the end of its + data, usually the last element of the BYHOUR array. This means that + next_day() should increment the time to the next day. If FREQUENCY==DAILY, + the routine increments the day by the interval; otherwise, it + increments the day by 1. + + Next_day() differs from next_hour because it does not use the BYDAY + array to select an appropriate day. Instead, it returns every day ( + incrementing by 1 if the frequency is not DAILY with INTERVAL!=1) + Any days that are not specified in an non-empty BYDAY array are + filtered out later. + + Generally, the flow of these routine is for a next_* call a next_* + routine of a lower interval ( next_day calls next_hour) and then to + possibly call an increment_* routine of an equal or higher + interval. ( next_day calls increment_monthday() ) + + When the call to the original next_* routine returns, + icalrecur_iterator_next() will check the returned data against other + BYrule parts to determine if is should be excluded by calling + check_contracting_rules. Generally, a contracting rule is any with a + larger time span than the interval. For instance, if + INTERVAL=DAILY, BYMONTH is a contracting rule part. + + Check_contracting_rules() uses check_restriction() to do its + work. Check_restriction() uses expand_map[] to determine if a rule + is contracting, and if it is, and if the BY rule part has some data, + then the routine checks if the value of a component of the time is + part of the byrule part. For instance, for "INTERVAL=DAILY; + BYMONTH=6,10", check_restriction() would check that the time value + given to it has a month of either 6 or 10. + icalrecurrencetype_test() + + Finally, icalrecur_iterator_next() does a few other checks on the + time value, and if it passes, it returns the time. + + ======================================================================*/ + +#ifdef HAVE_CONFIG_H +#include "config.h" +#endif + +#include "icalrecur.h" +#include "icalerror.h" +#include "icalmemory.h" +#include <stdlib.h> /* for malloc */ +#include <errno.h> /* for errno */ +#include <string.h> /* for icalmemory_strdup */ +#include <assert.h> +#include <limits.h> /* for SHRT_MAX */ + +#define TEMP_MAX 1024 + + + +enum byrule { + NO_CONTRACTION = -1, + BY_SECOND = 0, + BY_MINUTE = 1, + BY_HOUR = 2, + BY_DAY = 3, + BY_MONTH_DAY = 4, + BY_YEAR_DAY = 5, + BY_WEEK_NO = 6, + BY_MONTH = 7, + BY_SET_POS +}; + + + +struct icalrecur_iterator_impl { + + struct icaltimetype dtstart; + struct icaltimetype last; /* last time return from _iterator_next*/ + int occurrence_no; /* number of step made on this iterator */ + struct icalrecurrencetype rule; + + short days[366]; + short days_index; + + enum byrule byrule; + short by_indices[9]; + + + short *by_ptrs[9]; /* Pointers into the by_* array elements of the rule */ +}; + +int icalrecur_iterator_sizeof_byarray(short* byarray) +{ + int array_itr; + + for(array_itr = 0; + byarray[array_itr] != ICAL_RECURRENCE_ARRAY_MAX; + array_itr++){ + } + + return array_itr; +} + +enum expand_table { + UNKNOWN = 0, + CONTRACT = 1, + EXPAND =2, + ILLEGAL=3 +}; + +struct expand_split_map_struct +{ + icalrecurrencetype_frequency frequency; + + /* Elements of the 'map' array correspond to the BYxxx rules: + Second,Minute,Hour,Day,Month Day,Year Day,Week No,Month*/ + + short map[8]; +}; + +struct expand_split_map_struct expand_map[] = +{ + {ICAL_SECONDLY_RECURRENCE,1,1,1,1,1,1,1,1}, + {ICAL_MINUTELY_RECURRENCE,2,1,1,1,1,1,1,1}, + {ICAL_HOURLY_RECURRENCE, 2,2,1,1,1,1,1,1}, + {ICAL_DAILY_RECURRENCE, 2,2,2,1,1,1,1,1}, + {ICAL_WEEKLY_RECURRENCE, 2,2,2,2,3,3,1,1}, + {ICAL_MONTHLY_RECURRENCE, 2,2,2,2,2,3,3,1}, + {ICAL_YEARLY_RECURRENCE, 2,2,2,2,2,2,2,2}, + {ICAL_NO_RECURRENCE, 0,0,0,0,0,0,0,0} + +}; + + + +/* Check that the rule has only the two given interday byrule parts. */ +int icalrecur_two_byrule(struct icalrecur_iterator_impl* impl, + enum byrule one,enum byrule two) +{ + short test_array[9]; + enum byrule itr; + int passes = 0; + + memset(test_array,0,9); + + test_array[one] = 1; + test_array[two] = 1; + + for(itr = BY_DAY; itr != BY_SET_POS; itr++){ + + if( (test_array[itr] == 0 && + impl->by_ptrs[itr][0] != ICAL_RECURRENCE_ARRAY_MAX + ) || + (test_array[itr] == 1 && + impl->by_ptrs[itr][0] == ICAL_RECURRENCE_ARRAY_MAX + ) + ) { + /* test failed */ + passes = 0; + } + } + + return passes; + +} + +/* Check that the rule has only the one given interdat byrule parts. */ +int icalrecur_one_byrule(struct icalrecur_iterator_impl* impl,enum byrule one) +{ + int passes = 1; + enum byrule itr; + + for(itr = BY_DAY; itr != BY_SET_POS; itr++){ + + if ((itr==one && impl->by_ptrs[itr][0] == ICAL_RECURRENCE_ARRAY_MAX) || + (itr!=one && impl->by_ptrs[itr][0] != ICAL_RECURRENCE_ARRAY_MAX)) { + passes = 0; + } + } + + return passes; +} + +int count_byrules(struct icalrecur_iterator_impl* impl) +{ + int count = 0; + enum byrule itr; + + for(itr = BY_DAY; itr <= BY_SET_POS; itr++){ + if(impl->by_ptrs[itr][0] != ICAL_RECURRENCE_ARRAY_MAX){ + count++; + } + } + + return count; +} + + +void setup_defaults(struct icalrecur_iterator_impl* impl, + enum byrule byrule, icalrecurrencetype_frequency req, + short deftime, int *timepart) +{ + + icalrecurrencetype_frequency freq; + freq = impl->rule.freq; + + /* Re-write the BY rule arrays with data from the DTSTART time so + we don't hav to explicitly deal with DTSTART */ + + if(impl->by_ptrs[byrule][0] == ICAL_RECURRENCE_ARRAY_MAX && + expand_map[freq].map[byrule] != CONTRACT){ + impl->by_ptrs[byrule][0] = deftime; + } + + /* Initialize the first occurence */ + if( freq != req && expand_map[freq].map[byrule] != CONTRACT){ + *timepart = impl->by_ptrs[byrule][0]; + } + + +} + +int expand_year_days(struct icalrecur_iterator_impl* impl,short year); + + +icalrecur_iterator* icalrecur_iterator_new(struct icalrecurrencetype rule, struct icaltimetype dtstart) +{ + struct icalrecur_iterator_impl* impl; + icalrecurrencetype_frequency freq; + + if ( ( impl = (struct icalrecur_iterator_impl *) + malloc(sizeof(struct icalrecur_iterator_impl))) == 0) { + icalerror_set_errno(ICAL_NEWFAILED_ERROR); + return 0; + } + + memset(impl,0,sizeof(struct icalrecur_iterator_impl)); + + impl->rule = rule; + impl->last = dtstart; + impl->dtstart = dtstart; + impl->days_index =0; + impl->occurrence_no = 0; + freq = impl->rule.freq; + + /* Set up convienience pointers to make the code simpler.

+
+----------------------------------------------------------------
+
+The vCard/vCalendar C interface is implemented in the set
+of files as follows:
+
+vcc.y, yacc source, and vcc.c, the yacc output you will use
+implements the core parser
+
+vobject.c implements an API that insulates the caller from
+the parser and changes in the vCard/vCalendar BNF
+
+port.h defines compilation environment dependent stuff
+
+vcc.h and vobject.h are header files for their .c counterparts
+
+vcaltmp.h and vcaltmp.c implement vCalendar "macro" functions
+which you may find useful.
+
+test.c is a standalone test driver that exercises some of
+the features of the APIs provided. Invoke test.exe on a
+VCARD/VCALENDAR input text file and you will see the pretty
+print output of the internal representation (this pretty print
+output should give you a good idea of how the internal
+representation looks like -- there is one such output in the
+following too). Also, a file with the .out suffix is generated
+to show that the internal representation can be written back
+in the original text format.

+
+This document is mainly about the VObject and its APIs. The main
+use of a VObject is to represent a VCard or a VCalendar inside
+a program. However, its use is not limited to aforemention as it
+can represent an arbitrary information that makes up of a tree or
+forest of properties/values.
+
+1. VObject
+ =======
+A VObject can have a name (id) and a list of associated properties and
+a value. Each property is itself a VObject.
+
+2. Internal Representations of VCard/VCalendar
+ ===========================================
+A list of VCard or a VCalendar is represented by a list of VObjects.
+The name (id) of the VObjects in the list is either VCCardProp or
+VCCalProp. Each of these VObjects can have a list of properties.
+Since a property is represented as a VObject, each of these properties
+can have a name, a list of properties, and a value.
+

+will conceptually be be represented as

+ VCNameProp
+ VCFamilyNameProp=Alden
+ VCGivenNameProp=Roland
+ VCFullNameProp=Roland H.Alden
+ ....
+
+note that
+ EMAIL;WORK;PREF;INTERNET:sf!rincon!ralden@alden.attmail.com
+will be represented as:
+ VCEmailAddress=sf!rincon!ralden@alden.attmail.com
+ VCWork
+ VCPreferred
+ VCInternet
+where the lower level properties are properties of the property
+VCEmailAddress.
+
+Groupings are flattened out in the VObject representation such
+that:
+ a.b:blah
+ a.c:blahblah
+are represented as:
+ b=blah
+ VCGrouping=a
+ c=blahblah
+ VCGrouping=a
+i.e. one can read the above as:
+ the property "b" has value "blah" and property "VCGrouping"
+ with the value "a".
+ the property "c" has value "blahblah" and property "VCGrouping"
+ with the value "a".
+likewise, multi-level groupings are flatten similarly. e.g.
+ a.b.c:blah
+ a.b.e:blahblah
+-->
+ c=blah
+ VCGrouping=b
+ VCGrouping=a
+ e=blahblah
+ VCGrouping=b
+ VCGrouping=a
+which read:
+ the property "c" has value "blah" and property "VCGrouping"
+ with the value "b" which has property "VCGrouping"
+ with value "a".
+ the property "e" has value "blahblah" and property "VCGrouping"
+ with the value "b" which has property "VCGrouping"
+ with value "a".
+
+3. Iterating Through VObject's Properties or Values
+ ================================================
+The following is a skeletal form of iterating through
+all properties of a vobject, o:
+
+ // assume the object of interest, o, is of type VObject
+ VObjectIterator i;
+ initPropIterator(&i,o);
+ while (moreIteration(&i)) {
+ VObject *each = nextVObject(&i);
+ // ... do something with "each" property
+ }
+
+Use the API vObjectName() to access a VObject's name.
+Use the API vObjectValueType() to determine if a VObject has
+ a value. For VCard/VCalendar application, you
+ should not need this function as practically
+ all values are either of type VCVT_USTRINGZ or
+ VCVT_RAW (i.e set by setVObjectUStringZValue and
+ setVObjectAnyValue APIs respectively), and the
+ value returned by calls to vObjectUStringZValue
+ and vObjectAnyValue are 0 if a VObject has no
+ value. (There is a minor exception where VObject with
+ VCDataSizeProp has value that is set by
+ setVObjectLongValue).
+Use the APIs vObject???Value() to access a VObject's value.
+ where ??? is the expected type.
+Use the APIs setvObject???Value() to set or modify a VObject's value.
+ where ??? is the expected type.
+Use the API isAPropertyOf() to query if a name match the name of
+ a property of a VObject. Since isAPropertyOf() return
+ the matching property, we can use that to retrieve
+ a property and subsequently the value of the property.
+
+4. Pretty Printing a VObject Tree
+ ==============================
+VObject tree can be pretty printed with the printVObject() function.
+The output of pretty printing a VObject representation of the input
+test file "vobject.vcf" is shown below. Note that the indentation
+indicates the tree hirerarchy where the immediate children nodes
+of a parent node is all at the same indentation level and the
+immediate children nodes are the immediate properties of the
+associated parent nodes. In the following, {N,FN,ORG,TITLE,...}
+are immediate properties of VCARD. {F and G} are properties of N
+with value {"Alden" and "Roland"} respectively; FN has no property
+but has the value "Roland H. Alden"; EMAIL has value and
+the properties WORK, PREF, and INTERNET.

+5. Building A VObject Representation of A VCard/VCalendar
+ ======================================================
+The parser in vcc.y converts an input file with one or more
+VCard/VCalendar that is in their textual representation
+into their corresponding VObject representation.
+
+VObject representation of a VCard/VCalendar can also be built
+directly with calls to the VObject building APIs. e.g.
+
+ VObject *prop;
+ VObject *vcard = newVObject(VCCardProp);
+ prop = addProp(vcard,VCNameProp);
+ addPropValue(prop,VCFamilyNameProp,"Alden");
+ addPropValue(prop,VCGivenNameProp,"Roland");
+ addPropValue(vcard,VCFullNameProp,"Roland H. Alden");
+ ....
+
+6. Converting A VObject Representation Into Its Textual Representation
+ ===================================================================
+The VObject representation can be converted back to its textual
+representation via the call to writeVObject() or writeMemVObject()
+API. e.g.
+ a. to write to a file:
+ // assume vcard is of type VObject
+ FILE *fp = fopen("alden.vcf","w");
+ writeVObject(fp,vcard);
+ a. to write to memory, and let the API allocate the required memory.
+ char* clipboard = writeVObject(0,0,vcard);
+ ... do something to clipboard
+ free(clipboard);
+ b. to write to a user allocated buffer:
+ char clipboard[16384];
+ int len = 16384;
+ char *buf = writeVObject(clipboard,&len,vcard);
+ ... buf will be equal to clipboard if the write
+ is successful otherwise 0.
+
+In the case of writing to memory, the memory buffer can be either
+allocated by the API or the user. If the user allocate the
+memory for the buffer, then the length of the buffer needs to be
+communicated to the API via a variable. The variable passed as
+the length argument will be overwritten with the actual size
+of the text output. A 0 return value from writeMemVObject()
+indicates an error which could be caused by overflowing the
+size of the buffer or lack of heap memory.
+
+7. Miscellaneous Notes On VObject APIs usages
+ ==========================================
+a. vcc.h -- contains basic interfaces to the parser:
+ VObject* Parse_MIME(const char *input, unsigned long len);
+ VObject* Parse_MIME_FromFile(FILE *file);
+ -- both of this return a null-terminated list of
+ VObject that is either a VCARD or VCALENDAR.
+ To iterate through this list, do
+ VObject *t, *v;
+ v = Parse_Mime_FromFile(fp);
+ while (v) {
+ // ... do something to v.
+ t = v;
+ v = nextVObjectInList(v);
+ cleanVObject(t);
+ }
+ note that call to cleanVObject will release
+ resource used to represent the VObject.
+
+b. vobject.h -- contains basic interfaces to the VObject APIs.
+ see the header for more details.
+ The structure of VObject is purposely (hiddened) not exposed
+ to the user. Every access has to be done via
+ the APIs. This way, if we need to change the
+ structure or implementation, the client need not
+ recompile as long as the interfaces remain the
+ same.
+
+c. values of a property is determined by the property definition
+ itself. The vobject APIs does not attempt to enforce
+ any of such definition. It is the consumer responsibility
+ to know what value is expected from a property. e.g
+ most properties have unicode string value, so to access
+ the value of these type of properties, you will use
+ the vObjectUStringZValue() to read the value and
+ setVObjectUStringZValue() to set or modify the value.
+ Refer to the VCard and VCalendar specifications for
+ the definition of each property.
+
+d. properties name (id) are case incensitive.
+
+8. Brief descriptions of each APIs
+ ===============================
+ * the predefined properties' names (id) are listed under vobject.h
+ each is of the form VC*Prop. e.g.
+ #define VC7bitProp "7BIT"
+ #define VCAAlarmProp "AALARM"
+ ....
+
+ * consumer of a VObject can only define pointers to VObject.
+
+ * a variable of type VObjectIterator, say "i", can be used to iterate
+ through a VObject's properties, say "o". The APIs related to
+ VObjectIterator are:
+ void initPropIterator(VObjectIterator *i, VObject *o);
+ -- e.g. usage
+ initPropIterator(&i,o);
+ int moreIteration(VObjectIterator *i);
+ -- e.g. usage
+ while (moreIteration(&i)) { ... }
+ VObject* nextVObject(VObjectIterator *i);
+ -- e.g. usage
+ while (moreIteration(&i)) {
+ VObject *each = nextVObject(&i);
+ }
+
+ * VObject can be chained together to form a list. e.g. of such
+ use is in the parser where the return value of the parser is
+ a link list of VObject. A link list of VObject can be
+ built by:
+ void addList(VObject **o, VObject *p);
+ and iterated by
+ VObject* nextVObjectInList(VObject *o);
+ -- next VObjectInList return 0 if the list
+ is exhausted.
+
+ * the following APIs are mainly used to construct a VObject tree:
+ VObject* newVObject(const char *id);
+ -- used extensively internally by VObject APIs but when
+ used externally, its use is mainly limited to the
+ construction of top level object (e.g. an object
+ with VCCardProp or VCCalendarProp id).
+
+ void deleteVObject(VObject *p);
+ -- to deallocate single VObject, for most user, use
+ cleanVObject(VObject *o) instead for freeing all
+ resources associated with the VObject.
+
+ char* dupStr(const char *s, unsigned int size);
+ -- duplicate a string s. If size is 0, the string is
+ assume to be a null-terminated.
+
+ void deleteStr(const char *p);
+ -- used to deallocate a string allocated by dupStr();
+
+ void setVObjectName(VObject *o, const char* id);
+ -- set the id of VObject o. This function is not
+ normally used by the user. The setting of id
+ is normally done as part of other APIs (e.g.
+ addProp()).
+
+ void setVObjectStringZValue(VObject *o, const char *s);
+ -- set a string value of a VObject.
+
+ void setVObjectUStringZValue(VObject *o, const wchar_t *s);
+ -- set a Unicode string value of a VObject.
+
+ void setVObjectIntegerValue(VObject *o, unsigned int i);
+ -- set an integer value of a VObject.
+
+ void setVObjectLongValue(VObject *o, unsigned long l);
+ -- set an long integer value of a VObject.
+
+ void setVObjectAnyValue(VObject *o, void *t);
+ -- set any value of a VObject. The value type is
+ unspecified.
+
+ VObject* setValueWithSize(VObject *prop, void *val, unsigned int size);
+ -- set a raw data (stream of bytes) value of a VObject
+ whose size is size. The internal VObject representation
+ is
+ this object = val
+ VCDataSizeProp=size
+ i.e. the value val will be attached to the VObject prop
+ and a property of VCDataSize whose value is size
+ is also added to the object.
+
+ void setVObjectVObjectValue(VObject *o, VObject *p);
+ -- set a VObject as the value of another VObject.
+
+ const char* vObjectName(VObject *o);
+ -- retrieve the VObject's Name (i.e. id).
+
+ const char* vObjectStringZValue(VObject *o);
+ -- retrieve the VObject's value interpreted as

+
+9. Additional Programming Notes
+ ============================
+In the following notes, please refers to the listing
+of Example.vcf and its VObject Representation
+(shown at the end of this section).
+
+* Handling the Return Value of the VCard/VCalendar Parser
+ The example input text file contains two root VObjects
+ (a VCalendar and a VCard). The output of the VCard/VCalendar
+ parser is a null-terminated list of VObjects. For this
+ particular input file, the list will have two VObjects.
+ The following shows a template for iterating through the
+ output of the Parser:
+
+ VObject *t, *v;
+ v = Parse_Mime_fromFileName("example.vcf");
+ while (v) {
+ // currently, v will either be a VCard or a VCalendar
+ // do whatever your application need to do to
+ // v here ...
+ t = v;
+ v = nextVObjectInList(v);
+ cleanVObject(t);
+ }
+
+* Iterating Through a VCard/VCalendar VObject
+ From the VObject APIs point of view, a VCard VObject
+ is the same as a VCalendar VObject. However, the application
+ needs to know what are in a VCard or a VCalendar.
+ For example, A VCalendar VObject can have VCDCreatedProp,
+ a VCGEOLocationProp, etc, and one or more VCEventProp and
+ or VCTodoProp. The VCEventProp and VCTodoProp can have
+ many properties of their own, which in turn could have
+ more properties (e.g. VCDAlarmProp can be a VCEventProp
+ VObject's property, and VCRunTimeProp can be a
+ VCDAlarmProp VObject's property. Because a VObject tree
+ can be arbitrarily complex, in general, to process all
+ properties and values of a VObject tree, a recursive walk
+ is desirable. An example recursive VObject tree walk
+ can be found in the vobject.c source lines for printVObject*
+ and writeVObject* APIs. Depending on what the application need
+ to do with a VCard or a VCalendar, a recursive walk
+ of the VObject tree may or may not be desirable. An example
+ template of a non-recursive walk is shown below:
+
+ void processVCardVCalendar(char *inputFile)
+ {
+ VObject *t, *v;
+ v = Parse_Mime_fromFileName(inputFile);
+ while (v) {
+ char *n = vObjectName(v);
+ if (strcmp(n,VCCardProp) == 0) {
+ do_VCard(v);
+ }
+ else if (strcmp(n,VCCalendarProp) == 0) {
+ do_VCalendar(v);
+ }
+ else {
+ // don't know how to handle anything else!
+ }
+ t = v;
+ v = nextVObjectInList(v);
+ cleanVObject(t);
+ }
+ }
+
+ void do_VCard(VObject *vcard)
+ {
+ VObjectIterator t;
+ initPropIterator(&t,vcard);
+ while (moreIteration(&t)) {
+ VObject *eachProp = nextVObject(&t);
+ // The primarly purpose of this example is to
+ // show how to iterate through a VCard VObject,
+ // it is not meant to be efficient at all.
+ char *n = vObjectName(eachProp);
+ if (strcmp(n,VCNameProp)==0) {
+ do_name(eachProp);
+ }
+ else if (strcmp(n,VCEmailProp)==0) {
+ do_email(eachProp);
+ }
+ else if (strcmp(n,VCLabelProp)==0) {
+ do_label(eachProp);
+ }
+ else if ....
+ }
+ }
+
+ void do_VCalendar(VObject *vcal)
+ {
+ VObjectIterator t;
+ initPropIterator(&t,vcard);
+ while (moreIteration(&t)) {
+ VObject *eachProp = nextVObject(&t);
+ // The primarly purpose of this example is to
+ // show how to iterate through a VCalendar VObject,
+ // it is not meant to be efficient at all.
+ char *n = vObjectName(eachProp);
+ if (strcmp(n,VCDCreatedProp)==0) {
+ do_DCreated(eachProp);
+ }
+ else if (strcmp(n,VCVersionProp)==0) {
+ do_Version(eachProp);
+ }
+ else if (strcmp(n,VCTodoProp)==0) {
+ do_Todo(eachProp);
+ }
+ else if (strcmp(n,VCEventProp)==0) {
+ do_Event(eachProp);
+ }
+ else if ....
+ }
+ }
+
+ void do_Todo(VObject *vtodo) { ... }
+
+ void do_Event(VObject *vevent) { ... }
+
+ ...
+
+* Property's Values and Properties
+ The VObject APIs do not attempt to check for the
+ correctness of the values of a property. Nor do they
+ will prevent the user from attaching a non-VCard/VCalendar
+ standard property to a VCard/VCalendar property. Take
+ the example of line [11] of the example, "O.K" is not
+ a valid value of VCStatusProp. It is up to the application
+ to accept or reject the value of a property.
+
+* Output of printVObject
+ PrintVObject pretty prints a VObject tree in human
+ readable form. See the listing at the end of the file
+ for an example output of printVObject on the example
+ input file "Example.vcf".
+
+ Note that binary data are not shown in the output of
+ printVObject. Instead, a note is made ([raw data]) to
+ indicate that there exists such a binary data.
+
+* Note on Binary Data
+ When the value of a property is a binary data, it is only
+ useful to know the size of the binary data.
+
+ In the case of the VCard/VCalendar parser, it chooses
+ to represent the size information as a separate property
+ called VCDataSizeProp whose value is the size of the binary
+ data. The APIs sequence to construct the VObject subtree
+ of line [44] of Example.vcf is
+
+ // VObject *vcard;
+ VObject *p1 = addProp(vcard,VCLogoProp);
+ (void) addProp(p1,VCGIFProp);
+ (void) addProp(p1,VCBASE64Prop);
+ VObject *p2 = addProp(p1,VCDataSizeProp);
+ (void) setVObjectLongValue(p2,1482);
+ setVObjectAnyValue(vcard,...pointer to binary data);
+
+ Note the presence of VCBase64Prop will cause the
+ writeVObject API to output the binary data as BASE64 text.
+ For VCard/VCalendar application, having the VCBase64Prop
+ property is pratically always neccessary for property with
+ binary data as its value.
+
+* Note on Quoted-Printable String
+ String value with embedded newline are written out as
+ quoted-prinatable string. It is therefore important
+ to mark a property with a string value that has
+ one or more embedded newlines, with the VCQutedPrintableProp
+ property. e.g.
+
+ // VObject *root;
+ char *msg="To be\nor\nnot to be";
+ VObject *p = addPropValue(root,VCDescriptionProp,msg);
+ // the following is how you mark a property with
+ // a property. In this case, the marker is
+ // VCQuotedPrintableProp
+ addProp(p,VCQuotedPrintableProp);
+
+* Note on Unicode
+ Although, the current parser takes ASCII text file only,
+ string values are all stored as Unicode in the VObject tree.
+ For now, when using the VObject APIs to construct a
+ VObject tree, one should always convert ASCII string value
+ to a Unicode string value:
+
+ // VObject *root;
+ VObject *p = addProp(root,VCSomeProp);
+ setVObjectUStringZValue(p,fakeUnicode(someASCIIStringZvalue));
+
+ An API is provided to simplify the above process:
+
+ addPropValue(root,VCSomeProp,someASCIIStringZValue);
+
+ Note that someASCIISTringZValue is automatically converted to
+ Unicode by addPropValue API, where as, the former code
+ sequence do an explicit call to fakeUnicode.
+
+ To read back the value, one should use the vObjectUStringZValue
+ API not vObjectStringZValue API. The value returned by the
+ vObjectUStringZValue API is a Unicode string. If the application
+ do not know how to handle Unicode string, it can use the
+ fakeCString API to convert it back to ASCII string (as long
+ as the conversion is meaningful).
+
+ Note that fakeCString return a heap allocated memory. It is
+ important to call deleteStr on fakeCString return value if
+ it is not longer required (or there will be memory leak).
+
+ NOTE: Unfortunately, at the point when this document is written,
+ there is still no consensus on how Unicode is to be handled
+ in the textual representation of VCard/VCalendar. So, there
+ is no version of writeVObject and the parser to output and
+ input Unicode textual representation of VCard/VCalendar.
