Member Function Documentation

virtual size_t ReadData	(	DataChunk &	Buffer,
		KLVObjectPtr	Object,
		Position	Start = 0,
		size_t	Size = static_cast< size_t >(-1)
	)			[pure virtual]

Read data from the source into the KLVObject.

Parameters:

	Buffer	Reference to a buffer to receive the data
	Object	KLVObject which is requesting the data
	Start	Offset from the start of the KLV value to start reading
	Size	Number of bytes to read, if -1 all available bytes will be read (which could be billions!)

Returns:

The count of bytes read (may be less than Size if less available)

Note:

A call to ReadData must replace the current contents of the KLVObject's DataChunk with the new data - no original data should be preserved
