Description

This base class makes it easier to write TpSvcChannelTypeCall implementations by implementing its properties, and some of its methods.

Subclasses should fill in TpBaseCallChannelClass.accept, TpBaseCallChannelClass.add_content and TpBaseCallChannelClass.hangup virtual function.

Details

TpBaseCallChannel

typedef struct _TpBaseCallChannel TpBaseCallChannel;

A base class for call channel implementations

Since 0.17.5

struct TpBaseCallChannelClass

struct TpBaseCallChannelClass {
  TpBaseCallChannelVoidFunc set_ringing;
  TpBaseCallChannelVoidFunc set_queued;
  TpBaseCallChannelVoidFunc accept;
  TpBaseCallChannelAddContentFunc add_content;
  TpBaseCallChannelHangupFunc hangup;
};

The class structure for TpBaseCallChannel

TpBaseCallChannelVoidFunc set_ringing;

 Notify members that client is ringing.

TpBaseCallChannelVoidFunc set_queued;

 Notify members that call is queued.

TpBaseCallChannelVoidFunc accept;

 accept the call. Note that TpBaseMediaCallChannel subclasses should not override this virtual method, but TpBaseMediaCallChannelClass.accept instead.

TpBaseCallChannelAddContentFunc add_content;

 add content to the call. Implementation must call tp_base_call_channel_add_content(). Can be NULL if "mutable-contents" is FALSE.

TpBaseCallChannelHangupFunc hangup;

 hangup the call.

 a specific reason for the change, which may be a D-Bus error in the Telepathy namespace, a D-Bus error in any other namespace (for implementation-specific errors), or the empty string to indicate that the state change was not an error.

message :

 an optional debug message, to expediate debugging the potentially many processes involved in a call.
