org.eclipse.emf.validation.model
Class Category

java.lang.Object
  extended by 
org.eclipse.emf.validation.model.Category
All Implemented Interfaces:
Comparable< Category>

public class Category
extends Object
implements Comparable< Category>

A constraint category, defining a hierarchical organization of constraints. Categories can be individually and separately (no dependency on the hierarchy) enabled or disabled by the user. Enablement indicates whether the constraints in the category should be applied to the user's models.

Categories are naturally sorted by name for display purposes.

This class is intended to be used by clients of the validation framework.
