java.lang.Object
  com.itmusings.owiz.impl.CommandBase<InputType>
      com.itmusings.owiz.impl.Router<InputType>

All Implemented Interfaces:

AttachableCommand<InputType>, Command<InputType>

Direct Known Subclasses:

OgnlRouter

public abstract class Router<InputType>
extends CommandBase<InputType>
implements Command<InputType>, AttachableCommand<InputType>

A router is a command that executes one of several commands based on a routing string. The computation of the routing string is left to a sub class and hence this is an abstract class.
