Class CMMFAudioControllerCustomCommandParser

class CMMFAudioControllerCustomCommandParser : public CMMFCustomCommandParserBase;

Description

Custom command parser class to be used by controller plugins wishing to support audio controller commands.

The controller plugin must be derived from MMMFAudioControllerCustomCommandImplementor to use this class.

The controller plugin should create an object of this type and add it to the list of custom command parsers in the controller framework. See the following example code for details.

void CMMFAudioController::ConstructL()
    {
    // Construct custom command parsers
    CMMFAudioPlayDeviceCustomCommandParser* audPlayDevParser = CMMFAudioPlayDeviceCustomCommandParser::NewL(*this);
    CleanupStack::PushL(audPlayDevParser);
    AddCustomCommandParserL(*audPlayDevParser); //parser now owned by controller framework
    CleanupStack::Pop();//audPlayDevParser

    CMMFAudioRecordDeviceCustomCommandParser* audRecDevParser = CMMFAudioRecordDeviceCustomCommandParser::NewL(*this);
    CleanupStack::PushL(audRecDevParser);
    AddCustomCommandParserL(*audRecDevParser); //parser now owned by controller framework
    CleanupStack::Pop();//audRecDevParser

etc.
    }
