Constructor and Description
EMFModelComprehension(BaseIndexOptions options) Creates a model comprehension with the specified options.

Method Summary

Modifier and Type	Method and Description
boolean	isLoading(org.eclipse.emf.ecore.resource.Resource resource) Finds out whether the Resource is currently loading
boolean	onlySamplingFeature(org.eclipse.emf.ecore.EStructuralFeature feature) Decides whether a feature can only be sampled as there is no guarantee that proper notifications will be delivered by their implementation.
boolean	representable(org.eclipse.emf.ecore.EStructuralFeature feature) This feature can be represented in IQBase.
void	traverseFeature(EMFVisitor visitor, org.eclipse.emf.ecore.EObject source, org.eclipse.emf.ecore.EStructuralFeature feature, java.lang.Object target, java.lang.Integer position)
void	traverseModel(EMFVisitor visitor, org.eclipse.emf.common.notify.Notifier source) Resource filters not consulted here (for performance), because model roots are assumed to be pre-filtered.
void	traverseObject(EMFVisitor visitor, org.eclipse.emf.ecore.EObject source)
void	traverseObjectIfUnfiltered(EMFVisitor visitor, org.eclipse.emf.ecore.EObject targetObject)

void	traverseResourceSet(EMFVisitor visitor, org.eclipse.emf.ecore.resource.ResourceSet source)
void	tryResolveReference(org.eclipse.emf.ecore.EObject source, org.eclipse.emf.ecore.EReference reference) Can be called to attempt to resolve a reference pointing to one or more proxies, using eGet().
boolean	untraversableDirectly(org.eclipse.emf.ecore.EStructuralFeature feature) Should not traverse this feature directly.

Constructor Detail

EMFModelComprehension

public EMFModelComprehension(BaseIndexOptions options)

Creates a model comprehension with the specified options. The options are copied, therefore subsequent changes will not affect the comprehension.

Method Detail

untraversableDirectly

public boolean untraversableDirectly(org.eclipse.emf.ecore.EStructuralFeature feature)

Should not traverse this feature directly. It is still possible that it can be represented in IQBase if representable(EStructuralFeature) is true.

onlySamplingFeature

public boolean onlySamplingFeature(org.eclipse.emf.ecore.EStructuralFeature feature)

Decides whether a feature can only be sampled as there is no guarantee that proper notifications will be delivered by their implementation.

Such features are derived (and/or volatile) features that are not well-behaving.

representable

public boolean representable(org.eclipse.emf.ecore.EStructuralFeature feature)

This feature can be represented in IQBase.

traverseModel

public void traverseModel(EMFVisitor visitor,
                          org.eclipse.emf.common.notify.Notifier source)

Resource filters not consulted here (for performance), because model roots are assumed to be pre-filtered.

traverseResourceSet

public void traverseResourceSet(EMFVisitor visitor,
                                org.eclipse.emf.ecore.resource.ResourceSet source)

traverseResourceIfUnfiltered

public void traverseResourceIfUnfiltered(EMFVisitor visitor,
                                         org.eclipse.emf.ecore.resource.Resource resource)

traverseResource

public void traverseResource(EMFVisitor visitor,
                             org.eclipse.emf.ecore.resource.Resource source)

traverseObjectIfUnfiltered

public void traverseObjectIfUnfiltered(EMFVisitor visitor,
                                       org.eclipse.emf.ecore.EObject targetObject)

traverseObject

public void traverseObject(EMFVisitor visitor,
                           org.eclipse.emf.ecore.EObject source)

traverseFeature

public void traverseFeature(EMFVisitor visitor,
                            org.eclipse.emf.ecore.EObject source,
                            org.eclipse.emf.ecore.EStructuralFeature feature,
                            java.lang.Object target,
                            java.lang.Integer position)

Parameters:

position - optional: known position in multivalued collection (for more efficient proxy resolution)

tryResolveReference

public void tryResolveReference(org.eclipse.emf.ecore.EObject source,
                                org.eclipse.emf.ecore.EReference reference)

Can be called to attempt to resolve a reference pointing to one or more proxies, using eGet().

isLoading

public boolean isLoading(org.eclipse.emf.ecore.resource.Resource resource)

Finds out whether the Resource is currently loading
