Detailed Description

This abstract class is the superclass of all classes representing an outputstream of bytes.

Applications that need to define a subclass of OutputStream must always provide at least a method that writes one byte of output.

Member Function Documentation

virtual void BGOutputStream::write (unsigned char data) [pure virtual]

Writes one byte to stream.

This method is specialized in subclasses like FileOutputStream, etc. - therefore it is declared pure virtual.

Parameters:

data	One byte data

virtual long BGOutputStream::write (unsigned char * buffer, long offset, long len) [virtual]

Writes buffer to stream.

By default simply write(byte) is called. For better performance also this method should be overwritten.

Parameters:

buffer	Buffer which should be written to stream @paran offset Offset to use
len	Amount of bytes to write to stream

virtual void BGOutputStream::flush () [virtual]

Flush stream, all buffers are flushed and written to stream.

Default is empty. Special behaviour is defined in subclass like FileOutputStream.
