Detailed Description

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

Member Function Documentation

virtual void RWChainedCharArrayOutputStreamImp::clear

(

)

[virtual]

Resets the underlying buffer.

Implements RWCharArrayOutputStreamImp.

virtual void RWChainedCharArrayOutputStreamImp::close

(

)

[virtual]

This function calls flush().

Reimplemented from RWOutputStreamImp.

virtual void RWChainedCharArrayOutputStreamImp::flush

(

)

[virtual]

Forwards the flush() request to the internal RWChainedMemoryStreambuf object.

Implements RWOutputStreamImp.

virtual char* RWChainedCharArrayOutputStreamImp::getCharacterArray

(

)

[virtual]

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

Implements RWCharArrayOutputStreamImp.

virtual RWSize RWChainedCharArrayOutputStreamImp::getCharacterArraySize

(

)

const [virtual]

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

Implements RWCharArrayOutputStreamImp.

const RWChainedMemoryStreambuf& RWChainedCharArrayOutputStreamImp::getSinkBuff

(

)

const [inline, protected]

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

RWChainedMemoryStreambuf& RWChainedCharArrayOutputStreamImp::getSinkBuff

(

)

[inline, protected]

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

virtual RWCString RWChainedCharArrayOutputStreamImp::getString

(

)

[virtual]

Returns a narrow character string object containing the characters inserted into the stream since its creation.

Implements RWCharArrayOutputStreamImp.

virtual bool RWChainedCharArrayOutputStreamImp::isBad

(

)

const [virtual]

Returns true if the last operation performed on the internal RWChainedMemoryStreambuf object failed. Throws no exceptions.

Implements RWStreamImp.

virtual bool RWChainedCharArrayOutputStreamImp::isFail

(

)

const [virtual]

Returns true if the last operation performed on the external RWChainedMemoryStreambuf object failed

Implements RWStreamImp.

virtual bool RWChainedCharArrayOutputStreamImp::isGood

(

)

const [virtual]

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

Implements RWStreamImp.

static RWCharArrayOutputStream RWChainedCharArrayOutputStreamImp::make

(

void

)

[inline, static]

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

virtual void RWChainedCharArrayOutputStreamImp::write	(	const char *	charArray,
		RWSize	numChars
	)			[virtual]

Writes an array of narrow characters to the stream.

Parameters:

	charArray	A pointer to the first element of the array.
	numChars	The number of narrow characters to be written to the stream.

Implements RWCharOutputStreamImp.

virtual void RWChainedCharArrayOutputStreamImp::write

(

char

charValue

)

[virtual]

Writes a single narrow character to the stream.

Parameters:

charValue

The narrow character to be written to the stream.

Implements RWCharOutputStreamImp.
