Class ComposedEValidator

java.lang.Object
  org.eclipse.ocl.examples.emf.validation.validity.utilities.ComposedEValidator

All Implemented Interfaces:

org.eclipse.emf.ecore.EValidator

public class ComposedEValidator
extends java.lang.Object
implements org.eclipse.emf.ecore.EValidator

A ComposedEValidator supports validation over a list of EValidators, validation terminating prematurely at the first child EValidator that returns false.

A ComposedEValidator may be installed to displace an EValidator.Registry.INSTANCE entry. This in itself is harmless but since the EValidator.Registry.INSTANCE is global, any additional EValidators added to the ComposedEValidator should restrict their activities to ResourceSets in which they are required.
