Description

Demultiplex is a process to convert the single stream of (Integer, Object) messages sent from a Multiplex process on the other end of its in channel back into separate streams (its out channels). It assumes that Multiplex operates on the same size array of channels as its out array.

The protocol on the incoming multiplexed stream consists of an Integer, that represents the channel identity of the multiplexed data, followed by the multiplexed data.

Channel Protocols

Input Channels
in	java.lang.Integer, java.lang.Object	A channel index followed by the multiplexed data.
Output Channels
out[]	java.lang.Object	All channels in this package carry integers.

Parameters:

in - the input channel

out - the output channels
