Detailed Description

A write stream that writes to normal memory.

ZStreamW_Memory provides write stream access to normal memory. The memory is only referenced by the stream, no copy of it is taken, and no attempt is made to dispose it or otherwise interpret what kind of memory it might be. The caller is responsible for passing an address to which write access is permitted. The stream does not bound its accesses, it just writes the data it's passed and works its way through memory. If you need bounded access use a ZStreamWPos_Memory.

Member Function Documentation

void ZStreamW_Memory::Imp_CopyFromDispatch	(	const ZStreamR &	iStreamR,
		uint64	iCount,
		uint64 *	oCountRead,
		uint64 *	oCountWritten
	)			[virtual]

Invoke iStreamR's Imp_CopyTo method.

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

Reimplemented from ZStreamW.

void ZStreamW_Memory::Imp_CopyFrom	(	const ZStreamR &	iStreamR,
		uint64	iCount,
		uint64 *	oCountRead,
		uint64 *	oCountWritten
	)			[virtual]

Actually copy data to this stream from iStreamR.

The second part of the two-stage dispatch initiated by ZStreamR::CopyTo and ZStreamR::CopyAllTo. The default implementation calls sCopyReadToWrite. Override this method if your stream's data is in memory and thus can be modified by calling iStreamR's Read method.

sCopyReadToWrite

Reimplemented from ZStreamW.
