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.

Constructor & Destructor Documentation

virtual RWChainedCharArrayOutputStreamImp::~RWChainedCharArrayOutputStreamImp ( )

virtual

Destructor.

RWChainedCharArrayOutputStreamImp::RWChainedCharArrayOutputStreamImp ( )

inlineprotected

Constructor.

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.

RWChainedMemoryStreambuf& RWChainedCharArrayOutputStreamImp::getSinkBuff ( )

inlineprotected

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

const RWChainedMemoryStreambuf& RWChainedCharArrayOutputStreamImp::getSinkBuff ( ) const

inlineprotected

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  )

inlinestatic

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 ( char  charValue )

virtual

Writes a single narrow character to the stream.

Parameters

charValue

The narrow character to be written to the stream.

Implements RWCharOutputStreamImp.

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.
