Detailed Description

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

Constructor & Destructor Documentation

virtual RWCharToStreambufOutputStreamImp::~RWCharToStreambufOutputStreamImp ( )

virtual

Destructor.

RWCharToStreambufOutputStreamImp::RWCharToStreambufOutputStreamImp ( std::streambuf &  sinkBuff )

inlineprotected

Initializes the reference to the iostreams std::streambuf, that will be used as the sink of narrow characters.

Parameters

sinkBuff

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

Member Function Documentation

virtual void RWCharToStreambufOutputStreamImp::close ( )

virtual

This function calls flush(). The user is responsible for closing the iostreams std::streambuf used as the sink of narrow characters if necessary.

Exceptions

RWExternalStreamException

Thrown when the call to the internal iostreams std::streambuf object fails or any propagated exceptions from that call occur.

Reimplemented from RWOutputStreamImp.

virtual void RWCharToStreambufOutputStreamImp::flush ( )

virtual

Forward the flush request to the iostreams std::streambuf.

Exceptions

RWExternalStreamException

Thrown when the call to the internal iostreams std::streambuf object fails or any propagated exceptions from that call occur.

Implements RWOutputStreamImp.

std::streambuf& RWCharToStreambufOutputStreamImp::getSinkBuff ( )

inlineprotected

Returns a reference to the iostreams std::streambuf, which is used as the sink of narrow characters. Throws no exceptions.

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

inlineprotected

Returns a reference to the iostreams std::streambuf, which is used as the sink of narrow characters. Throws no exceptions.

virtual bool RWCharToStreambufOutputStreamImp::isBad ( ) const

virtual

Returns true if the last operation performed on the iostreams std::streambuf failed. Throws no exceptions.

Implements RWStreamImp.

virtual bool RWCharToStreambufOutputStreamImp::isFail ( ) const

virtual

Returns true if the last operation performed on the iostreams std::streambuf failed. Throws no exceptions.

Implements RWStreamImp.

virtual bool RWCharToStreambufOutputStreamImp::isGood ( ) const

virtual

Returns true if the last operation performed on the iostreams std::streambuf succeeded. Throws no exceptions.

Implements RWStreamImp.

static RWCharOutputStream RWCharToStreambufOutputStreamImp::make ( std::streambuf &  sink )

inlinestatic

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

Parameters

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

virtual void RWCharToStreambufOutputStreamImp::write ( char  charValue )

virtual

Writes a single narrow character to the iostreams std::streambuf.

Exceptions

RWExternalStreamException

Thrown when the call to the internal iostreams std::streambuf object fails or any propagated exceptions from that call occur.

Parameters

charValue

The narrow character to be written.

Implements RWCharOutputStreamImp.

virtual void RWCharToStreambufOutputStreamImp::write ( const char *  charArray, RWSize  numChars  )

virtual

Writes an array of narrow characters to the iostreams std::streambuf.

Exceptions

RWIncompleteStreamOperation

Thrown when the call to the internal iostreams std::streambuf object fails or any propagated exceptions from that call occur.

Parameters

charArray	A pointer to the first element of the array.
numChars	The number of narrow characters to be written.

Implements RWCharOutputStreamImp.
