extends AbstractEnvironment<org.eclipse.uml2.uml.Package,org.eclipse.uml2.uml.Classifier,org.eclipse.uml2.uml.Operation,org.eclipse.uml2.uml.Property,org.eclipse.uml2.uml.EnumerationLiteral,org.eclipse.uml2.uml.Parameter,org.eclipse.uml2.uml.State,org.eclipse.uml2.uml.CallOperationAction,org.eclipse.uml2.uml.SendSignalAction,org.eclipse.uml2.uml.Constraint,org.eclipse.uml2.uml.Class,org.eclipse.emf.ecore.EObject>

Implementation of the Environment for parsing OCL expressions on UML models. The UMLEnvironment uses a client-supplied resource set to look up UML Packages in UML resources. It also uses an EPackage registry to find the corresponding Ecore definitions of packages when evaluating expressions on instances of the UML model (in the case of evaluation on UML2-generated API objects).
