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.

Constructor & Destructor Documentation

OpalContext::OpalContext

(

)

Construct an unintialised OPAL context.

virtual OpalContext::~OpalContext ( )

virtual

Destroy the OPAL context, calls ShutDown().

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.

References m_handle.

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.
