Class AbstractEvaluationEnvironment

java.lang.Object
  org.eclipse.ocl.examples.pivot.AbstractBasicEnvironment<EvaluationEnvironment>
      org.eclipse.ocl.examples.pivot.evaluation.AbstractEvaluationEnvironment

All Implemented Interfaces:

DomainEvaluationEnvironment, Adaptable, BasicEnvironment, Customizable, EvaluationEnvironment

Direct Known Subclasses:

PivotEvaluationEnvironment

public abstract class AbstractEvaluationEnvironment
extends AbstractBasicEnvironment<EvaluationEnvironment>
implements EvaluationEnvironment

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.
