  cz.cuni.amis.pogamut.base.communication.translator.impl.WorldMessageTranslator

All Implemented Interfaces:

IWorldChangeEventOutput, IComponent

public class WorldMessageTranslator
extends java.lang.Object
implements IWorldChangeEventOutput

Abstract class for translators between world messages (InfoObjects) and IWorldEvents. It implements IWorldEventOutput interface meaning it can be given to the mediator as the source for IWorldEvents. It is constructed with parser that should provide parsed messages (translated text messages from the world to the java object wrappers) + IWorldMessageHandler that is given those parsed messages to produce IWorldEvents. It should process those messages into IWorldEvents and return them.

Ignores IComponentControlHelper.startPaused(), performs IComponentControlHelper.start() in both start cases.
