## Detailed Description

Local connection. This class represents a connection on the local machine that can receive media via virtual functions.

## Constructor & Destructor Documentation

OpalLocalConnection::OpalLocalConnection | ( | OpalCall & | call,
|  | OpalLocalEndPoint & | endpoint,
|  | void * | userData,
|  | unsigned | options,
|  | OpalConnection::StringOptions * | stringOptions,
|  | char | tokenPrefix = `'L'`
| ) |  |

Create a new connection.

Parameters:

  call | Owner call for connection
  endpoint | Owner endpoint for connection
  userData | Arbitrary data to pass to connection
  options | Option bit mask to pass to connection
  stringOptions | Options to pass to connection
  tokenPrefix | Prefix for token generation

OpalLocalConnection::~OpalLocalConnection | ( |  | ) |

Destroy connection.

## Member Function Documentation

virtual void OpalLocalConnection::AcceptIncoming | ( |  | ) |

virtual

Accept the incoming connection.

virtual void OpalLocalConnection::AlertingIncoming | ( |  | ) |

virtual

Indicate alerting for the incoming connection.

virtual OpalMediaStream* OpalLocalConnection::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:

  mediaFormat | Media format for stream
  sessionID | Session number for stream
  isSource | Is a source stream

Reimplemented from OpalConnection.

Reimplemented in OpalMixerConnection, OpalPCSSConnection, OpalIVRConnection, and OpalFaxConnection.

void* OpalLocalConnection::GetUserData | ( |  | ) | const

inline

Get user data pointer.

References userData.

virtual PBoolean OpalLocalConnection::IsNetworkConnection | ( |  | ) | const

inline virtual

Get indication of connection being to a "network". This indicates the if the connection may be regarded as a "network" connection. The distinction is about if there is a concept of a "remote" party being connected to and is best described by example: sip, h323, iax and pstn are all "network" connections as they connect to something "remote". While pc, pots and ivr are not as the entity being connected to is intrinsically local.

Implements OpalConnection.

Reimplemented in OpalIVRConnection.

virtual void OpalLocalConnection::OnApplyStringOptions | ( |  | ) |

virtual

Call back for connection to act on changed string options.

Reimplemented from OpalConnection.

Reimplemented in OpalMixerConnection.

virtual OpalMediaStreamPtr OpalLocalConnection::OpenMediaStream | ( | const OpalMediaFormat & | mediaFormat,
|  | unsigned | sessionID,
|  | bool | isSource
| ) |  |

virtual

Open source or sink media stream for session.

Parameters:

  mediaFormat | Media format to open
  sessionID | Session to start stream on
  isSource | Stream is a source/sink

Reimplemented from OpalConnection.

virtual PBoolean OpalLocalConnection::SendUserInputString | ( | const PString & | value | ) |

virtual

Send a user input indication to the remote endpoint. This sends an arbitrary string as a user indication. If DTMF tones in particular are required to be sent then the SendIndicationTone() function should be used.

The default behaviour plays the DTMF tones on the line.

Parameters:

  value | String value of indication

Reimplemented from OpalConnection.

Reimplemented in OpalMixerConnection, and OpalIVRConnection.

virtual PBoolean OpalLocalConnection::SetAlerting | ( | const PString & | calleeName,
|  | PBoolean | withMedia
| ) |  |

virtual

Indicate to remote endpoint an alert is in progress. If this is an incoming connection and the AnswerCallResponse is in a AnswerCallDeferred or AnswerCallPending state, then this function is used to indicate to that endpoint that an alert is in progress. This is usually due to another connection which is in the call (the B party) has received an OnAlerting() indicating that its remote endpoint is "ringing".

The default behaviour does nothing.

Parameters:

  calleeName | Name of endpoint being alerted.
  withMedia | Open media with alerting

Implements OpalConnection.

virtual PBoolean OpalLocalConnection::SetConnected | ( |  | ) |

virtual

Indicate to remote endpoint we are connected.

       The default behaviour sets the phase to ConnectedPhase, sets the
       connection start time and then checks if there is any media channels
       opened and if so, moves on to the established phase, calling
       OnEstablished().

       In other words, this method is used to handle incoming calls,
       and is an indication that we have accepted the incoming call.

Reimplemented from OpalConnection.

virtual PBoolean OpalLocalConnection::SetUpConnection | ( |  | ) |

virtual

Start an outgoing connection. This function will initiate the connection to the remote entity, for example in H.323 it sends a SETUP, in SIP it sends an INVITE etc.

The default behaviour does.

Implements OpalConnection.

void OpalLocalConnection::SetUserData | ( | void * | v | ) |

inline

Set user data pointer.
