#include <rw/stream/RWFilteredWCharOutputStreamImp.h>

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.

RWFilteredWCharOutputStreamImp(RWWCharOutputStream&
                               sinkStream);

Used by derived classes to initialize the next processing stream.

Parameter List

sinkStream

A handle to the next processing stream.

virtual 
~RWFilteredWCharOutputStreamImp();

Destructor.

virtual void 
close();

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

virtual void 
flush();

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

virtual bool 
isBad() const;

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

virtual bool 
isFail() const;

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

virtual bool 
isGood() const;

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

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

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

Parameter List

wcharArray	A pointer to the first element of the array.
numWChars	The number of wide characters to be written to the stream.

virtual void 
write(wchar_t wcharValue);

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

Parameter List

wcharValue

The wide character to be written.

RWWCharOutputStream& 
getSinkStream();

const RWWCharOutputStream& 
getSinkStream() const;

These functions return a handle to the next processing stream. They throw no exceptions.
