Class ValidationEngine

java.lang.Object

org.eclipse.viatra.addon.validation.core.ValidationEngine

All Implemented Interfaces:

IValidationEngine

public class ValidationEngine
extends java.lang.Object
implements IValidationEngine

This class uses an ViatraQueryEngine for tracking violations of ConstraintSpecifications. Use the builder() method for setting up a new instance through the ValidationEngineBuilder.
