Detailed Description

Class RWSynchronizedByteInputStreamImp implements a simple lock stream that is used with binary input stream. The stream locks its internal synchronization mechanism before forwarding input requests to its associated source stream, and then unlocks the internal synchronization mechanism upon completion. The stream's internal synchronization mechanism is locked using a guard object, ensuring its proper release in the event that an exception is thrown.

Constructor & Destructor Documentation

RWSynchronizedByteInputStreamImp::RWSynchronizedByteInputStreamImp ( const RWByteInputStream sourceStream)
protected

Initializes the reference to the input stream that will be used as the source of bytes.

Parameters
sourceStreamThe input stream that will serve as the source of bytes.

Member Function Documentation

static RWByteInputStream RWSynchronizedByteInputStreamImp::make ( const RWByteInputStream sourceStream)
inlinestatic

Constructs an RWSynchronizedByteInputStreamImp instance that uses sourceStream as the source of bytes, and returns a handle to it. Throws no exceptions.

Parameters
sourceStreamThe output stream that will serve as the source of bytes.
virtual RWSize RWSynchronizedByteInputStreamImp::readUntil ( RWByte byteArray,
RWSize  maxSize,
RWByte  delim 
)
virtual

Reads bytes from the attached source 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
byteArrayA pointer to the array receiving the byte(s) extracted from the stream.
maxSizeThe maximum number of byte(s) to be read.
delimThe byte value used as a delimiter.

Reimplemented from RWFilteredByteInputStreamImp.
