Member Function Documentation

virtual u_int32_t SH::SubGraphSH::getDelay (   )  const [pure virtual]

Implemented in SH::NopSubGraphSH.

virtual SinkEndpoint** SH::SubGraphSH::getSinkSpecs (   )  [protected, virtual]

Provide a list of valid sink endpoint specifications to the graph manager. getSinkPorts() is called by the graph manager and returns an array of pointers to EndpointSpec structures, or NULL if no endpoints in this direction are supported. It is typical that the length of such an array is 1, because several alternatives are specified by one EndpointSpec object, and the maximum number of identical Endpoints is a parameter of the EndpointSpec as well. The maximum number of endpoints may be dynamic, e.g. in an RTP source SH, new SSRCs or PTs will result in the provision of a new Endpoint. The array of endpoint specs is not NULL terminated, it is expected that the application knows the number of endpoints from numSinkSpecs(). Returns: An array of endpoint specification. Implements SH::Status.

virtual SourceEndpoint** SH::SubGraphSH::getSourceSpecs (   )  [protected, virtual]

Provide a list of valid source endpoint specifications to the graph manager. getSourceSpecs() works like getSinkSpecs() but on the source endpoint specifications. Returns: An array of endpoint specification. Implements SH::Status.

virtual bool SH::SubGraphSH::graphManNotify (  int  idx, SH::Base *  caller, SH::Notification  attribute, void *  msg )  [pure virtual]

SHGraphManager. Implements SHGraphManager. Implemented in SH::NopSubGraphSH.

virtual SH_RC SH::SubGraphSH::initSH (   )  [pure virtual]

SH. Reimplemented from SH::Base. Implemented in SH::NopSubGraphSH.

virtual bool SH::SubGraphSH::isConnected (   )  const [protected, virtual]

Indicate whether a sufficient number of endpoints are connected for the stream handler to be active. True if a sufficient number of endpoints is connected for the stream handler to operate in a graph. This should always be true when the stream handler is part of an active graph. This can be called on all stream handlers of a graph to determine whether it will activate successfully. Implements SH::Status.

virtual void SH::SubGraphSH::pushReport (  Report *  report, Direction  d )  [virtual]

bool SH::SubGraphSH::setInAnchorSH (  Base *  sh  )  [protected]

Sets the sink-endpoint of the given SH as the sink-endpoint of this SubGraphSH.

bool SH::SubGraphSH::setOutAnchorSH (  Base *  sh  )  [protected]

Sets the source-endpoint of the given SH as the source-endpoint of this SubGraphSH.

virtual SH_RC SH::SubGraphSH::startStreaming (   )  [pure virtual]

SH. Reimplemented from SH::Base. Implemented in SH::NopSubGraphSH.

virtual SH_RC SH::SubGraphSH::stopStreaming (   )  [pure virtual]

SH. Reimplemented from SH::Base. Implemented in SH::NopSubGraphSH.

virtual SH_RC SH::SubGraphSH::uninitSH (   )  [pure virtual]

SH. Reimplemented from SH::Base. Implemented in SH::NopSubGraphSH.
