This class is for H.323 Service Control Session handling for HTTP. This implements the HTTP channel management as per Annex K/H.323.

Constructor & Destructor Documentation

H323HTTPServiceControl::H323HTTPServiceControl

(

const PString &

url

)

Create a new handler for a Service Control.

(

const H225_ServiceControlDescriptor &

contents

)

Create a new handler for a Service Control, initialise to PDU.

Member Function Documentation

virtual PString H323HTTPServiceControl::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 from H323ServiceControlSession.

virtual PBoolean H323HTTPServiceControl::IsValid ( ) const

virtual

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

Default behaviour returns true if url is not an empty string.

Implements H323ServiceControlSession.

virtual void H323HTTPServiceControl::OnChange ( unsigned  type, unsigned  sessionId, H323EndPoint &  endpoint, H323Connection *  connection  ) const

virtual

Handle a change of the state of the Service Control Session.

Default behaviour calls endpoint.OnHTTPServiceControl().

Implements H323ServiceControlSession.

virtual PBoolean H323HTTPServiceControl::OnReceivedPDU ( const H225_ServiceControlDescriptor &  contents )

virtual

Handle a received PDU. Update in the internal state from the received PDU.

Default behaviour gets the contents for an e_url.

Implements H323ServiceControlSession.

virtual PBoolean H323HTTPServiceControl::OnSendingPDU ( H225_ServiceControlDescriptor &  contents ) const

virtual

Handle a sent PDU. Set the PDU fields from in the internal state.

Default behaviour sets the contents to an e_url.

Implements H323ServiceControlSession.
