public class CommandProcessor

extends java.lang.Object

Standard processor of Commands. Provides stub interfaces for all command types. For an entity to process a particular command, subclass this class and provide the implementation.

The CommandProcessor is truly the central place where commands are sent. To process them, each method will speak to various managers in the server, such as the serverPluginManager, tableManager, and userManager.
