Class XmlConstraintProvider


java.lang.Object
  

org.eclipse.emf.validation.service.AbstractConstraintProvider
      
org.eclipse.emf.validation.xml.XmlConstraintProvider

All Implemented Interfaces:: IExecutableExtension, IModelConstraintProvider

public class XmlConstraintProvider
extends AbstractConstraintProvider
implements IExecutableExtension
extends AbstractConstraintProvider
implements IExecutableExtension

A convenient implementation of the IModelConstraintProvider interface which loads constraints from a plug-in's manifest XML.

Constraints may be specified in the plugin.xml file or in separate XML files containing the <constraints> element as their root and included from the plug-in manifest via a <include> element. Includes can nest to any depth.

Constraints may be specified in any language for which some plug-in provides an implementation via the constraintParsers extension point. Currently, the "Java" language is provided by the core EMF Model Validation plug-in.

This class is intended to be used by clients by reference in the constraintProviders extension point. It is not intended to be subclassed or otherwise used by client code.
