java.lang.Objectorg.eclipse.ocl.AbstractEvaluationEnvironment<C,O,P,CLS,E>
public abstract class AbstractEvaluationEnvironment<C,O,P,CLS,E>
A partial implementation of the EvaluationEnvironment interface,
providing some useful common behaviors. Implementors of metamodel-specific
environments are encourage to extend this class rather than implement
an evaluation environment "from scratch."
See the Environment class for a description of the
generic type parameters of this class.
Since the 1.2 release, this interface is Adaptable to support the
optional adapter protocols such as EvaluationEnvironment.Enumerations
and Customizable.
