Class PivotScopeView

java.lang.Object
  org.eclipse.ocl.examples.pivot.scoping.PivotScopeView

All Implemented Interfaces:

ScopeView

public class PivotScopeView
extends java.lang.Object
implements ScopeView

ScopeViews support access to some or all of the elements in a scope. Accesses are filtered on the fly since a cache of results does not remain valid for long enough to merit it, with incremental reparsing regularly trashing the CST.

Field Summary

protected Element	child
protected boolean	isQualified
protected MetaModelManager	metaModelManager
static ScopeView	NULLSCOPEVIEW The NULLSCOPEVIEW to be returned by the most outer scope
protected Element	target

Constructor Summary

protected

PivotScopeView(MetaModelManager metaModelManager, Element target, Element child, boolean isQualified)

Method Summary

ScopeView	computeLookup(EnvironmentView environmentView, org.eclipse.emf.ecore.EObject aTarget)
Attribution	getAttribution() Return Attribution instance that defines the lookup algorithm for the target node.
Element	getChild() Return the immediate child node for which a lookup is requested.
org.eclipse.emf.ecore.EStructuralFeature	getContainmentFeature() Return the containment feature of the child within the target.
MetaModelManager	getMetaModelManager()
ScopeView	getParent() Return the ScopeView that characterizes a lookup in the parent of the target node.
ScopeView	getRoot() Return the ScopeView that characterizes a lookup at the top level.
Element	getTarget() Return the target node at which this ScopeView characterizes a lookup.
boolean	isQualified() Return true if the lookup is within a qualified name.
java.lang.String	toString()
