<tp:docstring xmlns="http://www.w3.org/1999/xhtml">
<p>A <i>tube</i> is a mechanism for arbitrary data transfer between
two or more IM users, used to allow applications on the users'
systems to communicate without having to establish network
connections themselves. Currently, two types of tube exist:
<tp:dbus-ref namespace="org.freedesktop.Telepathy"
>Channel.Type.DBusTube</tp:dbus-ref> and
<tp:dbus-ref namespace="org.freedesktop.Telepathy"
>Channel.Type.StreamTube</tp:dbus-ref>. This interface contains
the properties, signals and methods common to both types of tube;
you can only create channels of a specific tube type, not of this
type. A tube channel contains exactly one tube; if you need several
tubes, you have to create several tube channels.</p>
<p>Tube channels can be requested for handles of type
HANDLE_TYPE_CONTACT (for 1-1 communication) or of type
HANDLE_TYPE_ROOM (to communicate with others in the room
simultaneously).</p>
</tp:docstring>
<property name="Parameters" type="a{sv}" tp:type="String_Variant_Map"
access="readwrite" tp:name-for-bindings="Parameters">
<tp:docstring xmlns="http://www.w3.org/1999/xhtml">
<p>Each tube has a dictionary of arbitrary parameters. Parameters are
commonly used to bootstrap legacy protocols where you can't
negotiate parameters in-band. The allowable keys,
types and values are defined by the service. Connection managers
must support the value being a string (D-Bus type 's'), array of bytes
(D-Bus type 'ay'), unsigned integer (D-Bus type 'u'), integer (D-Bus
type 'i') and boolean (D-Bus type 'b').</p>
<p>When the tube is offered, the parameters are transmitted with the
offer and appear as a property of the incoming tube for other
participants.</p>
<p>Example of valid parameters for 'smb' Server Message Block over
TCP/IP (from <a href="http://www.dns-sd.org/ServiceTypes.html">DNS
SRV (RFC 2782) Service Types
http://www.dns-sd.org/ServiceTypes.html</a>):
<code>{'u': 'username', 'p': 'password', 'path': 'path'}</code></p>
<p>When requesting a channel with
<tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.Interface.Requests.CreateChannel</tp:dbus-ref>,
this property MAY be included in the request. If it is not included in
the request, the connection manager MUST consider the property to be
empty. This property MAY be changed after the channel creation when
the tube is in the state Not_Offered. If the tube is in another
state, changing this property MUST fail without side effects.</p>

<tp:docstring>
The initiator offered the tube. The tube is waiting to be

<tp:docstring>
The initiator offered the tube and the recipient accepted it. The
tube is open for traffic. The tube's state stays in this state until
it is closed.

<tp:docstring>

the tube type.
