Class OCLQueryDelegateFactory

java.lang.Object
  org.eclipse.ocl.examples.pivot.delegate.AbstractOCLDelegateFactory
      org.eclipse.ocl.examples.pivot.delegate.OCLQueryDelegateFactory

All Implemented Interfaces:

org.eclipse.emf.ecore.util.QueryDelegate.Factory

Direct Known Subclasses:

OCLQueryDelegateFactory.Global

public class OCLQueryDelegateFactory
extends AbstractOCLDelegateFactory
implements org.eclipse.emf.ecore.util.QueryDelegate.Factory

Factory for OCL query delegates.

The factory may be obtained by:

 QueryDelegate.Factory factory = QueryDelegate.Factory.Registry.INSTANCE
                .getFactory(OCLDelegateDomain.OCL_DELEGATE_URI);
 

from which a query delegate may be created by:

 QueryDelegate delegate = factory.createQueryDelegate(
                classifier,                 // the context type
                map-of-name-to-classifier,  // the external variable names and types
                string);                    // the OCL expression text
 

and (repeatedly) invoked by:

 Object result = delegate.execute(
                target,                     // the context instance
                map-of-name-to-object);     // the external variable bindings
