Member Function Documentation

void ZStrimW_Null::Imp_CopyFromDispatch	(	const ZStrimR &	iStrimR,
		size_t	iCountCP,
		size_t *	oCountCPRead,
		size_t *	oCountCPWritten
	)			[virtual]

Invoke iStrimR's Imp_CopyTo method.

The first part of the two-stage dispatch initiated by CopyFrom and CopyAllFrom. Override if your strim's data is in memory and thus iStrimR can have its Read method called with your strim's data as its destination.

Reimplemented from ZStrimW.

void ZStrimW_Null::Imp_CopyFrom	(	const ZStrimR &	iStrimR,
		size_t	iCountCP,
		size_t *	oCountCPRead,
		size_t *	oCountCPWritten
	)			[virtual]

Actually copy data to this strim from iStrimR.

The second part of the two-stage dispatch initiated by CopyFrom and CopyAllFrom. The default implementation calls sCopyReadToWrite. Override this method if your strim's data is in memory and thus can be modified by calling iStrimR's Read method.

Reimplemented from ZStrimW.
