   public InChannelDispatcher() 

Default constructor

   static InChannelDispatcher getDispatcher(ProtocolLayer pl,

Get the dispatcher that matches the given source mask.

Parameter	Description
pl	The protocol layer were packets are coming from
source	The source address mask packets are matched too

   void addChannel(InChannel newChan) 

Add a channel to this dispatcher. The channel is placed in the selection line by how large its key is, the larger the key the earlier it will be checked.

   void remChannel(InChannel deadChan) 

Remove a channel from this dispatcher.
