Interface EventPipeline

All Known Implementing Classes:

CommandManager

public interface EventPipeline

An EventPipeline is used by the ThreadManager to manage the event Queue and EventHandler relationship. The ThreadManager manages the automatic forwarding of the Events from the queue to the Event Handler.

The interface design is heavily influenced by Matt Welsh's SandStorm server, his demonstration of the SEDA architecture. We have deviated where we felt the design differences where better.
