public class GreifarmActor
extends IUModule

GreifarmActor is the NLU and action management component for the Greifarm prototype (as the Greifarm prototype is not really a "dialogue system", but rather a speech-controlled application, we avoid the term "dialog manager") This class consists of the following components, which all live in their own subclasses:

GreifarmActor: the incremental processor (PushBuffer) which handles incoming IUs and initiates the corresponding processing. This class handles the global list of performed actions and of the words yet to process, as well as references to the NLU component, the greifarm handling, and the game score. It also provides a global logger.

NLU: processes incoming words and (depending on what has been done before) initiates actions (in the form of ActionIUs)

ActionIU: these IUs are generated, executed and put into the list of performed actions by the NLU.

Greifarm: handles concurrency stuff related to the greifarm GUI (which itself lives in GreifArmGUI
