A HyperChannel.class performs NIO/TCP-IP based multicast.

  What is a HyperChannel in a sentence?
It is java(TM) class which allows various forms of NIO based multicast.
HyperChannels has several possible IO transit resolutions.
           
1) A SocketChannel for external incoming connections.
           
2) A ChannelView.class
         
3) A Memory mapped File.
    
3) Standard output.

HyperChannel.class
    You get a reference from a HyperChannel by calling the appropriate
static HyperChannelRegistry.class method with the appropriate HyperChannel.name
String.

Creating and/or getting a reference to a HyperChannel.

ie:
   HyperChannel myChannel = HyperChannel.getChannel("MyChannel");
If the HyperChannel exists a reference to the Channel is returned.
Else if the HyperChannel does not exist, then it is created, and
then its reference to it is returned.  If there is some type of
error, then the call returns null.
