Detailed Description

Concrete class implementing the byte array output stream interface. Bytes inserted into an instance of class RWChainedByteArrayOutputStreamImp are stored in memory using an instance of class RWChainedMemoryStreambuf. Implements the body idiom from the handle-body pattern.

Constructor & Destructor Documentation

virtual RWChainedByteArrayOutputStreamImp::~RWChainedByteArrayOutputStreamImp ( )

virtual

Destructor.

RWChainedByteArrayOutputStreamImp::RWChainedByteArrayOutputStreamImp ( )

inlineprotected

Constructor.

Member Function Documentation

virtual void RWChainedByteArrayOutputStreamImp::clear ( )

virtual

Resets the underlying buffer.

Implements RWByteArrayOutputStreamImp.

virtual void RWChainedByteArrayOutputStreamImp::close ( )

virtual

This function calls flush().

Reimplemented from RWOutputStreamImp.

virtual void RWChainedByteArrayOutputStreamImp::flush ( )

virtual

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

Implements RWOutputStreamImp.

virtual RWByte* RWChainedByteArrayOutputStreamImp::getByteArray ( )

virtual

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

Implements RWByteArrayOutputStreamImp.

virtual RWSize RWChainedByteArrayOutputStreamImp::getByteArraySize ( ) const

virtual

Returns the size of the byte array that would be returned by a call to function getByteArray().

Implements RWByteArrayOutputStreamImp.

RWChainedMemoryStreambuf& RWChainedByteArrayOutputStreamImp::getSinkBuff ( )

inlineprotected

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

const RWChainedMemoryStreambuf& RWChainedByteArrayOutputStreamImp::getSinkBuff ( ) const

inlineprotected

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

virtual bool RWChainedByteArrayOutputStreamImp::isBad ( ) const

virtual

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

Implements RWStreamImp.

virtual bool RWChainedByteArrayOutputStreamImp::isFail ( ) const

virtual

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

Implements RWStreamImp.

virtual bool RWChainedByteArrayOutputStreamImp::isGood ( ) const

virtual

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

Implements RWStreamImp.

static RWByteArrayOutputStream RWChainedByteArrayOutputStreamImp::make ( void  )

inlinestatic

Constructs an RWChainedByteArrayOutputStreamImp instance that uses an instance of class RWChainedMemoryStreambuf to store bytes. The function returns a handle to the implementation class.

virtual void RWChainedByteArrayOutputStreamImp::write ( RWByte  byteValue )

virtual

Writes a single byte to the iostreams std::streambuf. Throws exception RWExternalStreamException.

Parameters

byteValue

The byte to be written.

Implements RWByteOutputStreamImp.

virtual void RWChainedByteArrayOutputStreamImp::write ( const RWByte *  byteArray, RWSize  numBytes  )

virtual

Writes an array of bytes to the iostreams std::streambuf. Throws exception RWIncompleteStreamOperation.

Parameters

byteArray	A pointer to the first element of the array.
numBytes	The number of bytes to be written.

Implements RWByteOutputStreamImp.
