Detailed Description

Abstract base class for all the data from narrow character conversion input stream implementation classes. A conversion input stream, is a stream that uses an attached input stream of a different format as the source of elements to its own functions. Implements the body idiom from the handle-body pattern.

Constructor & Destructor Documentation

virtual RWDataFromCharInputStreamImp::~RWDataFromCharInputStreamImp ( )

virtual

Destructor. Throws no exceptions.

RWDataFromCharInputStreamImp::RWDataFromCharInputStreamImp ( const RWCharInputStream &  sourceStream )

inlineprotected

Used by derived classes to initialize the attached source stream.

Parameters

sourceStream

A handle to the attached source stream.

Member Function Documentation

virtual RWSize RWDataFromCharInputStreamImp::available ( ) const

virtual

Returns the number of narrow characters that can be read from the attached source stream without blocking. Throws no exceptions

Implements RWInputStreamImp.

Reimplemented in RWIstreamDataFromCharInputStreamImp.

virtual void RWDataFromCharInputStreamImp::close ( )

virtual

Forwards the close() request to the attached source stream.

Implements RWStreamImp.

Reimplemented in RWIstreamDataFromCharInputStreamImp.

RWCharInputStream& RWDataFromCharInputStreamImp::getSourceStream ( )

inlineprotected

Returns a handle to the attached source stream. They throw no exceptions.

const RWCharInputStream& RWDataFromCharInputStreamImp::getSourceStream ( ) const

inlineprotected

Returns a handle to the attached source stream. They throw no exceptions.

virtual bool RWDataFromCharInputStreamImp::isBad ( ) const

virtual

Forwards the isBad() request to the attached source stream. Throws no exceptions.

Implements RWStreamImp.

Reimplemented in RWIstreamDataFromCharInputStreamImp.

virtual bool RWDataFromCharInputStreamImp::isEof ( ) const

virtual

Forwards the isEof() request to the attached source stream. Throws no exceptions.

Implements RWInputStreamImp.

Reimplemented in RWIstreamDataFromCharInputStreamImp.

virtual bool RWDataFromCharInputStreamImp::isFail ( ) const

virtual

Forwards the isFail() request to the attached source stream. Throws no exceptions

Implements RWStreamImp.

virtual bool RWDataFromCharInputStreamImp::isGood ( ) const

virtual

Forwards the isGood() request to the attached source stream. Throws no exceptions.

Implements RWStreamImp.

Reimplemented in RWIstreamDataFromCharInputStreamImp.

virtual RWSize RWDataFromCharInputStreamImp::skip ( RWSize  numUnits )

virtual

Skips numUnits narrow characters from the input sequence of the attached source stream if possible. The function returns the actual number of narrow characters skipped, which can be any value between 0 and numUnits.

Parameters

numUnits

The number of narrow characters to be skipped.
