Description

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

Subclasses should fill in TpBaseCallContentClass.get_interfaces, and TpBaseCallContentClass.deinit virtual function.

Details

TpBaseCallContent

typedef struct _TpBaseCallContent TpBaseCallContent;

A base class for call content implementations

Since 0.17.5

struct TpBaseCallContentClass

struct TpBaseCallContentClass {
  TpBaseCallContentDeinitFunc deinit;
  TpBaseCallContentGetInterfacesFunc get_interfaces;

  TpBaseCallContentStartToneFunc start_tone;
  TpBaseCallContentStopToneFunc stop_tone;
  TpBaseCallContentMultipleTonesFunc multiple_tones;
};

The class structure for TpBaseCallContent

TpBaseCallContentDeinitFunc deinit;

 optional; virtual method called by TpBaseCallChannel when removing the content

TpBaseCallContentGetInterfacesFunc get_interfaces;

 extra interfaces provided by this content (this SHOULD NOT include TP_IFACE_CALL_CONTENT itself). Implementation must first chainup on parent class implementation then add extra interfaces into the GPtrArray.

TpBaseCallContentStartToneFunc start_tone;

 optional; virtual method called when user requested to send a DTMF tone. Note that this method is already implemented by TpBaseMediaCallContent and so does not have to be overriden when using that subclass

TpBaseCallContentStopToneFunc stop_tone;

 optional; virtual method called when user requested to stop sending currently being played DTMF tones. Note that this method is already implemented by TpBaseMediaCallContent and so does not have to be overriden when using that subclass

TpBaseCallContentMultipleTonesFunc multiple_tones;

 optional; virtual method called when user requested to send multiple DTMF tones. Note that this method is already implemented by TpBaseMediaCallContent and so does not have to be overriden when using that subclass
