Member Function Documentation

virtual PString H323ServiceControlSession::GetServiceControlType ( ) const

virtual

Get identification name for the Control Service. This function separates the dynamic data from the fundamental type of the control service which will cause a new session ID to be generated by the gatekeeper server.

Default behaviour returns the class name.

Reimplemented in H323HTTPServiceControl.

virtual PBoolean H323ServiceControlSession::IsValid ( ) const

pure virtual

Determine of the session is valid. That is has all of the data it needs to correctly encode a PDU.

Default behaviour is pure.

Implemented in H323CallCreditServiceControl, and H323HTTPServiceControl.
