Constructor & Destructor Documentation

ZStreamR_MD5::ZStreamR_MD5	(	uint8	oDigest[16],
		const ZStreamR &	iStreamSource
	)

Constructor for use inline.

This constructor remembers the address of oDigest, and when destroyed will place the digest in that array. This constructor is useful when a ZStreamR is already being used to read some data, but for which we would like to gather a digest. e.g. going from this:

sourceStream.Read(dest, destSize);

to this:

uint8 theDigest[16];
ZStreamR_MD5(theDigest, sourceStream).Read(dest, destSize);

Member Function Documentation

size_t ZStreamR_MD5::Imp_CountReadable

(

)

[virtual]

Returns the number of bytes guaranteed to be readable without blocking.

If the stream does not or cannot know this information it should return zero. A zero return thus does not mean no data is available, simply that a subsequent Read or Skip may block indefinitely.

Reimplemented from ZStreamR.
