Synopsis

#include <rw/auditbuf.h>
#include <iostream>
RWAuditStreamBuffer buf(arguments)
std::ostream os(&buf); // may be used for ostreams
std::istream is(&buf); // or istreams of any kind

Description

Class RWAuditStreamBuffer is used to construct a stream, after which the RWAuditStreamBuffer instance will count all the bytes that pass through the stream. If constructed with a function pointer, RWAuditStreamBuffer will call that function with each byte that passes through the stream. The counting capacity provides for streams the equivalent of the RWCollectable method recursiveStoreSize() which is only available for RWFile.

Persistence

None
