public interface CommandProcessor

This is defined the basic interface to which all implementations must comply. A command processor adds on to the standard Gof Command Pattern and provides a central location for executing commands that further decouples the caller from the operation. More advance command processor implementations can keep track of the commands they've run and perhaps replay them or roll them back. For more information, see "A System of Patterns", Buschmann, et al..
