  +--org.apache.avalon.excalibur.command.CommandManager

All Implemented Interfaces:

EventPipeline

public class CommandManager

extends java.lang.Object

implements EventPipeline

The CommandManager handles asynchronous commands from the rest of the system. The only exposed piece is the Queue that other components use to give Commands to this system. You must register this with a ThreadManager for it to work.
