Constructor & Destructor Documentation

CCMRMediaBuffer()

CCMRMediaBuffer

(

)

[inline]

C++ constructors. The 1st creates a buffer to be initialized later with Set, and the 2nd one initializes it already here

CCMRMediaBuffer(const TPtrC8 &, const TBufferType, const TInt, const TBool, const TTimeIntervalMicroSeconds &)

CCMRMediaBuffer	(	const TPtrC8 &	aBuffer,
		const TBufferType	aType,
		const TInt	aSize,
		const TBool	aRandomAccessPoint,
		const TTimeIntervalMicroSeconds &	aTimeStamp
	)	[inline]

Parameters

const TPtrC8 & aBuffer
const TBufferType aType
const TInt aSize
const TBool aRandomAccessPoint
const TTimeIntervalMicroSeconds & aTimeStamp
