-
- icalstore manages a database of ical components and offers
- interfaces for reading, writting and searching for components.
-
- icalstore groups components in to clusters based on their DTSTART
- time -- all components that start in the same month are grouped
- together in a single file. All files in a sotre are kept in a single
- directory. ( If a component does not have DTSTART, the store uses
- DTSTAMP or CREATE )
-
- The primary interfaces are icalstore_first and icalstore_next. These
- routine iterate through all of the components in the store, subject
- to the current gauge. A gauge is an icalcomponent that is tested
- against other componets for a match. If a gauge has been set with
- icalstore_select, icalstore_first and icalstore_next will only
- return componentes that match the gauge.
-
- The Store generated UIDs for all objects that are stored if they do
- not already have a UID. The UID is the name of the cluster (month &
- year as MMYYYY) plus a unique serial number. The serial number is
- stored as a property of the cluster.

-
- The gauge is a VCALENDAR component that specifies how to test the

- VJOURNAL sub-components. Each of the sub-components has a
- collection of properties that are compared to corresponding
- properties in the target component, according to the

-
- When a gauge has several sub-components, the results of testing the
- target against each of them is ORed together - the target
- component will pass if it matches any of the sub-components in the
- gauge. However, the results of matching the proeprties in a
- sub-component are ANDed -- the target must match every property in
- a gauge sub-component to match the sub-component.
-
- Here is an example:
-
- BEGIN:XROOT
- BEGIN:VCOMPONENT
- BEGIN:VEVENT
- DTSTART;X-LIC-COMPARETYPE=LESS:19981025T020000
- ORGANIZER;X-LIC-COMPARETYPE=EQUAL:mrbig@host.com

- LOCATION;X-LIC-COMPARETYPE=EQUAL:McNary's Pub

- END:VCALENDAR
- END:XROOT
-
- This gauge has two sub-components; one which will match a VEVENT
- based on start time, and organizer, and another that matches based
- on LOCATION. A target component will pass the test if it matched
- either of the sub-components.
