Streams

Module Description

The Streams package includes concrete stream classes and a modular framework, which allows streams to be connected to each other to form complex chains of streaming elements.

The Streams package uses the handle-body pattern to allow complex streaming elements to be returned by value. It has two handle classes (input and output) for each stream family, as well as abstract body classes. Applications manipulate streams through their handle classes, which isolate them from concrete stream classes and ensure a uniform interface to any class within a stream family.

For complete information about the Streams package, see the Advanced Tools Module User's Guide.

typedef RWTStreamGuardImp<RWByteInputStream, RWFilteredByteInputStreamImp> RWGuardedByteInputStreamImp

Header File

#include <rw/stream/RWGuardedByteInputStreamImp.h>

The typedef RWGuardedByteInputStreamImp implements a simple binary guard input stream. The input stream guard acquires the synchronization mechanism provided by its source stream at construction time, and releases it upon destruction. The input guard stream doesn't maintain its own synchronization mechanism, but uses the one provided by the next processing stream. If the next processing stream doesn't implement any synchronization mechanism, the input stream guard class has no effect. The guard class is generally used in combination with class RWSynchronizedByteInputStreamImp.
