Detailed Description

Abstract base class for all the filtered wide character output stream implementation classes. A filtered output stream is a stream that process elements and then forwards the result to another stream for further processing. Implements the body idiom from the handle-body pattern.

Constructor & Destructor Documentation

virtual RWFilteredWCharOutputStreamImp::~RWFilteredWCharOutputStreamImp ( )
virtual

Destructor. Throws no exceptions.

RWFilteredWCharOutputStreamImp::RWFilteredWCharOutputStreamImp ( const RWWCharOutputStream sinkStream)
inlineprotected

Used by derived classes to initialize the next processing stream.

Parameters
sinkStreamA handle to the next processing stream.

Member Function Documentation

virtual void RWFilteredWCharOutputStreamImp::close ( )
virtual

Forwards the close() request to the next processing stream.

Reimplemented from RWOutputStreamImp.

virtual void RWFilteredWCharOutputStreamImp::flush ( )
virtual

Forwards the flush() request to the next processing stream.

Implements RWOutputStreamImp.

RWWCharOutputStream& RWFilteredWCharOutputStreamImp::getSinkStream ( )
inlineprotected

Returns a handle to the next processing stream. Throws no exceptions.

const RWWCharOutputStream& RWFilteredWCharOutputStreamImp::getSinkStream ( ) const
inlineprotected

Returns a handle to the next processing stream. Throws no exceptions.

virtual bool RWFilteredWCharOutputStreamImp::isBad ( ) const
virtual

Forwards the isBad() request to the next processing stream. Throws no exceptions.

Implements RWStreamImp.

virtual bool RWFilteredWCharOutputStreamImp::isFail ( ) const
virtual

Forwards the isFail() request to the next processing stream. Throws no exceptions.

Implements RWStreamImp.

virtual bool RWFilteredWCharOutputStreamImp::isGood ( ) const
virtual

Forwards the isGood() request to the next processing stream. Throws no exceptions.

Implements RWStreamImp.

virtual void RWFilteredWCharOutputStreamImp::write ( wchar_t  wcharValue)
virtual

Forwards the writing of a single wide character to the next processing stream.

Parameters
wcharValueThe wide character to be written.

Implements RWWCharOutputStreamImp.

virtual void RWFilteredWCharOutputStreamImp::write ( const wchar_t *  wcharArray,
RWSize  numWChars 
)
virtual

Forwards the writing of an array of wide characters to the next processing stream.

Parameters
wcharArrayA pointer to the first element of the array.
numWCharsThe number of wide character(s) to be written to the stream.

Implements RWWCharOutputStreamImp.
