Class TransformationStep

java.lang.Object

org.eclipse.viatra.integration.mwe2.mwe2impl.TransformationStep

All Implemented Interfaces:

ITransformationStep

public abstract class TransformationStep
extends java.lang.Object
implements ITransformationStep

The TransformationStep abstract class implements the ITransformationStep and adds further basic functions that are typically present in case of (VIATRA based) model transformation steps. These include the following: 1. Support for containing ISubscribeTo and IPublishTo objects 2. Process all incoming messages 3. Support the addition of user defined execute functionality and message publication
