Detailed Description

Abstract base class for all the binary input stream implementation classes. Implements the body idiom from the handle-body pattern.

Constructor & Destructor Documentation

~RWByteInputStreamImp()

virtual RWByteInputStreamImp::~RWByteInputStreamImp ( )

inlinevirtual

Destructor.

RWByteInputStreamImp()

RWByteInputStreamImp::RWByteInputStreamImp ( )

inlineprotected

Constructor.

Member Function Documentation

acquire()

virtual RWByteInputStream RWByteInputStreamImp::acquire ( )

virtual

Acquires the synchronization mechanism provided by a stream concrete implementation. The acquire() member function returns a handle to the binary stream that should be used for input operation after acquiring the synchronization mechanism.

Reimplemented in RWTInputStreamLockImp< RWByteInputStream, RWFilteredByteInputStreamImp >.

read() [1/2]

virtual RWByte RWByteInputStreamImp::read ( )

pure virtual

Reads a single byte from the stream.

Implemented in RWByteFromStreambufInputStreamImp, RWFilteredByteInputStreamImp, and RWTInputStreamLockImp< RWByteInputStream, RWFilteredByteInputStreamImp >.

read() [2/2]

virtual RWSize RWByteInputStreamImp::read ( RWByte * byteArray, RWSize numBytes )

pure virtual

Reads an array of bytes from the stream. The array must be pre-allocated to contain at least of numBytes elements. The function returns the actual number of bytes read from the stream.

Parameters

byteArray	A pointer to the first element of the array.
numBytes	The number of bytes to be read from the stream.

Implemented in RWByteFromStreambufInputStreamImp, RWFilteredByteInputStreamImp, and RWTInputStreamLockImp< RWByteInputStream, RWFilteredByteInputStreamImp >.

readUntil()

virtual RWSize RWByteInputStreamImp::readUntil ( RWByte * byteArray, RWSize maxSize, RWByte delim )

pure virtual

Reads bytes from the stream until the last byte read is equal to delim, or maxSize bytes have been read, or the end of the input sequence is reached. The bytes read are stored in byteArray. The function returns the actual number of bytes read from the stream.

Parameters

byteArray	A pointer to the array receiving the bytes extracted from the stream.
maxSize	The maximum number of bytes to be read.
delim	The byte value used as a delimiter.

Implemented in RWByteFromStreambufInputStreamImp, RWFilteredByteInputStreamImp, and RWSynchronizedByteInputStreamImp.

release()

virtual void RWByteInputStreamImp::release ( void )

inlinevirtual

Releases the synchronization mechanism provided by a stream concrete implementation.

Reimplemented in RWTInputStreamLockImp< RWByteInputStream, RWFilteredByteInputStreamImp >.
