Detailed Description

This class is a wrapper around the "C" API.

It may seem odd to have a C++ wrapper around a "C" API which is itself a wrapper around a C++ API, but sometimes a C++ programmer may wish to access the OPAL system via this simplified API instead of the quite complex one in the base OPAL library.

Member Function Documentation

bool OpalContext::AnswerCall

(

const char *

callToken

)

Answer a call using OpalCmdAnswerCall via OpalSendMessage().

Parameters:

callToken

Call token for call being answered.

bool OpalContext::ClearCall	(	const char *	callToken,
		OpalCallEndReason	reason = OpalCallEndedByLocalUser
	)

Clear a call using OpalCmdClearCall via OpalSendMessage().

Parameters:

callToken	Call token for call being cleared.
reason	Code for the call termination, see OpalCmdClearCall.

bool OpalContext::GetMessage	(	OpalMessagePtr &	message,
		unsigned	timeout = 0
	)

Calls OpalGetMessage() to get next message from the OPAL context.

unsigned OpalContext::Initialise	(	const char *	options,
		unsigned	version = OPAL_C_API_VERSION
	)

Calls OpalIntialise() to initialise the OPAL context. Returns version of API supported by library, zero if error.

Parameters:

options	List of options to pass to OpalIntialise()
version	Version expected by application

bool OpalContext::IsInitialised

(

)

const [inline]

Indicate if the OPAL context has been initialised.

bool OpalContext::SendMessage	(	const OpalMessagePtr &	message,
		OpalMessagePtr &	response
	)

Calls OpalSendMessage() to send a message to the OPAL context.

Parameters:

message	Message to send to OPAL.
response	Response from OPAL.

bool OpalContext::SendUserInput	(	const char *	callToken,
		const char *	userInput,
		unsigned	duration = 0
	)

Send user input using OpalCmdUserInput via OpalSendMessage().

Parameters:

callToken	Call token for the call, see OpalCmdUserInput.
userInput	User input string, e.g. "#", see OpalCmdUserInput.
duration	Duration in milliseconds for tone, see OpalCmdUserInput.

bool OpalContext::SetUpCall	(	OpalMessagePtr &	response,
		const char *	partyB,
		const char *	partyA = NULL,
		const char *	alertingType = NULL
	)

Execute OpalSendMessage() using OpalCmdSetUpCall.

Parameters:

response	Response from OPAL context on initiating call.
partyB	Destination address, see OpalCmdSetUpCall.
partyA	Calling sub-system, see OpalCmdSetUpCall.
alertingType	Alerting type code, see OpalCmdSetUpCall.

void OpalContext::ShutDown

(

)

Calls OpalShutDown() to dispose of the OPAL context.
