                                     throws java.lang.Exception
Description copied from interface: PackCompressor
Returns a newly created output stream which write method writes the given input encoded to the defined output stream. Attention! This method will be returned a valid output stream only if it is used in the IzPack compiler, or if this pack compressor needs no external classes. A call in the installation should be throw if external classes are used. The implementation should load the needed classes via reflection because classes are not present in the installation.

Parameters:
os - output stream to be used as listener
Returns:
a newly created encoding output stream
Throws:
java.lang.Exception
