Detailed Description

Concrete class connecting a binary stream to an iostreams narrow character buffer. The iostreams buffer is used as the sink for the data written to the binary stream. The iostreams buffer must be opened in binary mode. Implements the body idiom from the handle-body pattern.

Constructor & Destructor Documentation

virtual RWByteToStreambufOutputStreamImp::~RWByteToStreambufOutputStreamImp ( )

virtual

Destructor.

RWByteToStreambufOutputStreamImp::RWByteToStreambufOutputStreamImp ( std::streambuf &  sinkBuff )

inlineprotected

Initializes the reference to the iostreams std::streambuf, used as the sink of bytes.

Parameters

sinkBuff

The iostreams std::streambuf that will serve as the sink of bytes.

Member Function Documentation

virtual void RWByteToStreambufOutputStreamImp::close ( )

virtual

This function calls flush(). The user is responsible for closing the iostreams std::streambuf used as the sink of bytes, if necessary. Throws RWExternalStreamException and propagates any other exception thrown by the internal std::iostreams streambuf object.

Reimplemented from RWOutputStreamImp.

virtual void RWByteToStreambufOutputStreamImp::flush ( )

virtual

Forward the flush request to the iostreams std::streambuf. Throws RWExternalStreamException and propagates any other exception thrown by the internal iostreams std::streambuf object.

Implements RWOutputStreamImp.

std::streambuf& RWByteToStreambufOutputStreamImp::getSinkBuff ( )

inlineprotected

Returns a reference to the iostreams std::streambuf, which is used as the sink of bytes.

const std::streambuf& RWByteToStreambufOutputStreamImp::getSinkBuff ( ) const

inlineprotected

Returns a const reference to the iostreams std::streambuf, which is used as the sink of bytes.

virtual bool RWByteToStreambufOutputStreamImp::isBad ( ) const

virtual

Returns true if the last operation performed on the iostreams std::streambuf failed.

Implements RWStreamImp.

virtual bool RWByteToStreambufOutputStreamImp::isFail ( ) const

virtual

Returns true if the last operation performed on the iostreams std::streambuf failed.

Implements RWStreamImp.

virtual bool RWByteToStreambufOutputStreamImp::isGood ( ) const

virtual

Returns true if the last operation performed on the iostreams std::streambuf succeeded.

Implements RWStreamImp.

static RWByteOutputStream RWByteToStreambufOutputStreamImp::make ( std::streambuf &  sink )

inlinestatic

Constructs an RWByteToStreambufOutputStreamImp instance that uses sink as its sink of bytes, and returns a handle to it. Throws no exceptions.

Parameters

sink	The iostreams std::streambuf that is used as the sink of bytes.

virtual void RWByteToStreambufOutputStreamImp::write ( RWByte  byteValue )

virtual

Writes a single byte to the iostreams std::streambuf. Throws exception RWExternalStreamException and propagates any other exception thrown by the internal iostreams std::streambuf object.

Parameters

byteValue

The byte to be written.

Implements RWByteOutputStreamImp.

virtual void RWByteToStreambufOutputStreamImp::write ( const RWByte *  byteArray, RWSize  numBytes  )

virtual

Writes an array of bytes to the iostreams std::streambuf. Throws exception RWIncompleteStreamOperation and propagates any other exception thrown by the internal iostreams std::streambuf object.

Parameters

byteArray	A pointer to the first element of the array.
numBytes	The number of bytes to be written.

Implements RWByteOutputStreamImp.
