 An array of structures containing:
  • a string channel type
  • a bitwise OR of type specific capability flags
 An array of D-Bus interface names of channel types to remove An array of structures describing the current capabilities containing:
  • a string channel type
  • a bitwise OR of type specific capability flags

Used by user interfaces to indicate which channel types they are able to handle on this connection. Because these may be provided by different client processes, this method accepts channel types to add and remove from the set already advertised on this connection. The type of advertised capabilities (create versus invite) is protocol-dependent and hence cannot be set by the this method. In the case of a client adding an already advertised channel type but with new channel type specific flags, the connection manager should simply add the new flags to the set of advertised capabilities.

Upon a successful invocation of this method, the CapabilitiesChanged signal will be emitted for the user's own handle (as returned by GetSelfHandle) the by the connection manager to indicate the changes that have been made. This signal should also be monitored to ensure that the set is kept accurate - for example, a client may remove capabilities or type specific capability flags when it exits which are still provided by another client.

 An array of structures containing:
  • an integer handle representing the contact
  • a string channel type
  • a bitwise OR of the contact's old generic capability flags
  • a bitwise OR of the contact's new generic capability flags
  • a bitwise OR of the contact's old type specific capability flags
  • a bitwise OR of the contact's new type specific capability flags
 Announce that there has been a change of capabilities on the given handle, or on the connection itself if the handle is zero. An array of contact handles for this connection, or zero to query capabilities available on the connection itself An array of structures containing:
  • an integer handle representing the contact
  • a string channel type
  • a bitwise OR of generic capability flags for the type
  • a bitwise OR of type specific capability flags for the type
 Returns an array of capabilities for the given contact handles, or the connection itself (where handle is zero). The handle does not represent a contact

An interface for connections where it is possible to know what channel types may be requested before the request is made to the connection object. Each capability represents a commitment by the connection manager that it will ordinarily be able to create a channel when given a request with the given type and handle.

Capabilities can pertain to a certain contact handle, representing activities such as having a text chat or a voice call with the user, or can be on the connection itself (where the handle will be zero), where they represent the ability to create channels for chat rooms or activities such as searching and room listing. The activities are represented by the D-Bus interface name of the channel type for that activity.

The generic capability flags are defined by ConnectionCapabilityFlag.

In addition, channel types may have type specific capability flags of their own, which are described in the documentation for each channel type.

This interface also provides for user interfaces notifying the connection manager of what capabilities to advertise for the user. This is done by using the AdvertiseCapabilities method, and deals with the interface names of channel types and the type specific flags pertaining to them which are implemented by available client processes.

 The given channel type and handle can be given to RequestChannel to create a new channel of this type. The given contact can be invited to an existing channel of this type.
