Detailed Description

This class allows to divert the byte stream to two different outputs. This may be useful to perform an output while performing a parallel processing of the streamed data: size computation, checksumming, etc.

Member Function Documentation

flush()

int flush ( void  )

overridevirtual

Cause the current stream to dump its buffer to the medium.

Returns

0 for success, less than 0 for error.

Implements OutStream.

References OutStream::flush().

lastErrorMessage()

cstring lastErrorMessage ( void  )

overridevirtual

Return a message for the last error.

Returns

Message of the last error.

Reimplemented from OutStream.

References OutStream::lastErrorMessage().

supportsANSI()

bool supportsANSI ( ) const

overridevirtual

Test if the current stream knows how to decode ANSI special codes. The default implementation returns false.

Returns

True if ANSI code are supported, false else.

Reimplemented from OutStream.

References OutStream::supportsANSI().

write()

int write ( const char *  buffer, int  size  )

overridevirtual

This is the main method of an output stream: the given buffer is put on the stream.

Parameters

buffer	Byte buffer to write.
size	Size of the byte buffer.

Returns

Number of transferred bytes or less than 0 for an error.

Implements OutStream.

References OutStream::write().
