Detailed Description

Mixer connection.

Constructor & Destructor Documentation

OpalMixerConnection::OpalMixerConnection ( PSafePtr< OpalMixerNode node,
OpalCall call,
OpalMixerEndPoint endpoint,
void *  userData,
unsigned  options = 0,
OpalConnection::StringOptions stringOptions = NULL 
)

Create a new connection.

Parameters
nodeNode the connection is in
callOwner calll for connection
endpointOwner endpoint for connection
userDataArbitrary data to pass to connection
optionsOption bit map to be passed to connection
stringOptionsOptions to be passed to connection
OpalMixerConnection::~OpalMixerConnection ( )

Destroy connection.

Member Function Documentation

virtual OpalMediaStream* OpalMixerConnection::CreateMediaStream ( const OpalMediaFormat mediaFormat,
unsigned  sessionID,
PBoolean  isSource 
)
virtual

Open a new media stream. This will create a media stream of an appropriate subclass as required by the underlying connection protocol. For instance H.323 would create an OpalRTPStream.

The sessionID parameter may not be needed by a particular media stream and may be ignored. In the case of an OpalRTPStream it us used.

Note that media streams may be created internally to the underlying protocol. This function is not the only way a stream can come into existance.

The default behaviour is pure.

Parameters
mediaFormatMedia format for stream
sessionIDSession number for stream
isSourceIs a source stream

Reimplemented from OpalLocalConnection.

virtual bool OpalMixerConnection::GetConferenceState ( OpalConferenceState state) const
virtual

Get Conference state information. This obtains the state information about a conference this connection is directly a part of. If the connection type does not embody a conference then false is returned.

The state parameter, if non-NULL, is illed with the state of the conference. When NULL, this just indicates that the connection is part of a conference with the return value.

Default behaviour is to return false which indicates this connection is not part of a conference.

Parameters
stateOptional conference state information

Reimplemented from OpalConnection.

bool OpalMixerConnection::GetListenOnly ( ) const
inline

Get flag for this connection is in listen only mode.

References m_listenOnly.

virtual OpalMediaFormatList OpalMixerConnection::GetMediaFormats ( ) const
virtual

Get the data formats this connection is capable of operating. This provides a list of media data format names that a OpalMediaStream may be created in within this connection.

The default behaviour calls GetMediaFormats() on the endpoint.

Reimplemented from OpalConnection.

PSafePtr<OpalMixerNode> OpalMixerConnection::GetNode ( ) const
inline

Get the node that this connection is being mxied in.

References m_node.

virtual void OpalMixerConnection::OnApplyStringOptions ( )
virtual

Call back for connection to act on changed string options.

Reimplemented from OpalLocalConnection.

virtual void OpalMixerConnection::OnReleased ( )
virtual

Clean up the termination of the connection. This function can do any internal cleaning up and waiting on background threads that may be using the connection object.

Note that there is not a one to one relationship with the OnEstablishedConnection() function. This function may be called without that function being called. For example if SetUpConnection() was used but the call never completed.

Classes that override this function should make sure they call the ancestor version for correct operation.

An application will not typically call this function as it is used by the OpalManager during a release of the connection.

The default behaviour calls the OpalEndPoint function of the same name.

Reimplemented from OpalConnection.

virtual void OpalMixerConnection::OnStartMediaPatch ( OpalMediaPatch patch)
virtual

Call back when media stream patch thread starts.

Parameters
patchPatch being started

Reimplemented from OpalConnection.

virtual PBoolean OpalMixerConnection::SendUserInputString ( const PString &  value)
virtual

Send a user input indication to the remote endpoint. This is for sending arbitrary strings as user indications.

The default behaviour is to call SendUserInputTone() for each character in the string.

Parameters
valueString value of indication

Reimplemented from OpalLocalConnection.

virtual PBoolean OpalMixerConnection::SendUserInputTone ( char  tone,
unsigned  duration = 0 
)
virtual

Send a user input indication to the remote endpoint. This sends DTMF emulation user input. If something more sophisticated than the simple tones that can be sent using the SendUserInput() function.

A duration of zero indicates that no duration is to be indicated. A non-zero logical channel indicates that the tone is to be syncronised with the logical channel at the rtpTimestamp value specified.

The tone parameter must be one of "0123456789#*ABCD!" where '!' indicates a hook flash. If tone is a ' ' character then a signalUpdate PDU is sent that updates the last tone indication sent. See the H.245 specifcation for more details on this.

The default behaviour sends the tone using RFC2833.

Parameters
toneDTMF tone code
durationDuration of tone in milliseconds

Reimplemented from OpalConnection.

void OpalMixerConnection::SetListenOnly ( bool  listenOnly)

Set this connection to listen only mode.

Parameters
listenOnlyNew listen only state.
