24 <p>A <i>tube</i> is a mechanism for arbitrary data transfer between
25 two or more IM users, used to allow applications on the users'
26 systems to communicate without having to establish network
27 connections themselves. Currently, two types of tube exist:
28 <tp:dbus-ref namespace="org.freedesktop.Telepathy"
29 >Channel.Type.DBusTube</tp:dbus-ref> and
30 <tp:dbus-ref namespace="org.freedesktop.Telepathy"
31 >Channel.Type.StreamTube</tp:dbus-ref>. This interface contains
32 the properties, signals and methods common to both types of tube;
33 you can only create channels of a specific tube type, not of this
34 type. A tube channel contains exactly one tube; if you need several
35 tubes, you have to create several tube channels.</p>
37 <p>Tube channels can be requested for handles of type
38 HANDLE_TYPE_CONTACT (for 1-1 communication) or of type
39 HANDLE_TYPE_ROOM (to communicate with others in the room

46 <p>Each tube has a dictionary of arbitrary parameters. Parameters are
47 commonly used to bootstrap legacy protocols where you can't
48 negotiate parameters in-band. The allowable keys,
49 types and values are defined by the service. Connection managers
50 must support the value being a string (D-Bus type 's'), array of bytes
51 (D-Bus type 'ay'), unsigned integer (D-Bus type 'u'), integer (D-Bus
52 type 'i') and boolean (D-Bus type 'b').</p>
53 <p>When the tube is offered, the parameters are transmitted with the
54 offer and appear as a property of the incoming tube for other

63 this property MAY be included in the request. If it is not included in
64 the request, the connection manager MUST consider the property to be
65 empty. This property MAY be changed after the channel creation when
66 the tube is in the state Not_Offered. If the tube is in another
67 state, changing this property MUST fail without side effects.</p>
