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.

const RWChainedMemoryStreambuf& RWChainedWCharArrayOutputStreamImp::getSinkBuff

(

)

const [inline, protected]

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

RWChainedMemoryStreambuf& RWChainedWCharArrayOutputStreamImp::getSinkBuff

(

)

[inline, protected]

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

)

[inline, static]

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	(	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.

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.
