Detailed Description

Concrete class implementing the wide character array output stream interface. Wide character inserted into an instance of class RWChainedWCharArrayOutputStreamImp are stored in memory using an instance of class RWChainedMemoryStreambuf. Implements the body idiom from the handle-body pattern.

Constructor & Destructor Documentation

virtual RWChainedWCharArrayOutputStreamImp::~RWChainedWCharArrayOutputStreamImp ( )

virtual

Destructor.

RWChainedWCharArrayOutputStreamImp::RWChainedWCharArrayOutputStreamImp ( )

inlineprotected

Constructor.

Member Function Documentation

virtual void RWChainedWCharArrayOutputStreamImp::clear ( )

virtual

Reset the underlying buffer.

Implements RWWCharArrayOutputStreamImp.

virtual void RWChainedWCharArrayOutputStreamImp::close ( )

virtual

This function calls flush().

Reimplemented from RWOutputStreamImp.

virtual void RWChainedWCharArrayOutputStreamImp::flush ( )

virtual

Forward the flush request to the internal RWChainedMemoryStreambuf object.

Implements RWOutputStreamImp.

RWChainedMemoryStreambuf& RWChainedWCharArrayOutputStreamImp::getSinkBuff ( )

inlineprotected

Returns a reference to the RWChainedMemoryStreambuf, which is used as the sink of wide characters.

const RWChainedMemoryStreambuf& RWChainedWCharArrayOutputStreamImp::getSinkBuff ( ) const

inlineprotected

Returns a reference to the RWChainedMemoryStreambuf, which is used as the sink of wide characters.

virtual wchar_t* RWChainedWCharArrayOutputStreamImp::getWCharacterArray ( )

virtual

Returns a pointer to an array of wide characters containing the wide characters inserted into the stream since its creation, or since the last invocation of function getWCharacterArray(), or function clear(). Users are responsible for freeing the memory associated with the array returned by this function, by using operator delete[].

Implements RWWCharArrayOutputStreamImp.

virtual RWSize RWChainedWCharArrayOutputStreamImp::getWCharacterArraySize ( ) const

virtual

Returns the size of the wide character array that would be returned by a call to function getWCharacterArray().

Implements RWWCharArrayOutputStreamImp.

virtual bool RWChainedWCharArrayOutputStreamImp::isBad ( ) const

virtual

Return true if the last operation performed on the internal RWChainedMemoryStreambuf object failed.

Implements RWStreamImp.

virtual bool RWChainedWCharArrayOutputStreamImp::isFail ( ) const

virtual

Return true if the last operation performed on the internal RWChainedMemoryStreambuf object failed.

Implements RWStreamImp.

virtual bool RWChainedWCharArrayOutputStreamImp::isGood ( ) const

virtual

Returns true if the last operation performed on the internal RWChainedMemoryStreambuf object succeeded.

Implements RWStreamImp.

static RWWCharArrayOutputStream RWChainedWCharArrayOutputStreamImp::make ( void  )

inlinestatic

Constructs an RWChainedWCharArrayOutputStreamImp instance that uses an instance of class RWChainedMemoryStreambuf to store wide characters. The function returns a handle to the implementation class.

virtual void RWChainedWCharArrayOutputStreamImp::write ( wchar_t  wcharValue )

virtual

Writes a single wide character to the stream. Throws exception RWIncompleteStreamOperation.

Parameters

wcharValue

The wide character to be written.

Implements RWWCharOutputStreamImp.

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

virtual

Writes an array of wide characters to the stream. Throws exception RWIncompleteStreamOperation.

Parameters

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

Implements RWWCharOutputStreamImp.
