Interface PersistentResource

All Superinterfaces:

AutoCloseable, Closeable, Notifier, Resource, Resource.Internal

All Known Implementing Classes:

DefaultPersistentResource, PersistentResourceDecorator

public interface PersistentResource
extends Resource, Resource.Internal, Closeable

Extends the Resource interface by providing efficient model-level operations that are not accessible using the standard EMF API. For example, getAllInstances is a utility method that computes efficiently all the instances of a given type by delegating the operation to the underlying database, that can benefits of its internal optimizations and indices.

Method Detail

close

void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

eStore

InternalEObject.EStore eStore()

Returns the InternalEObject.EStore used to store the model.

Returns:

the InternalEObject.EStore

getAllInstances

EList<EObject> getAllInstances(EClass eClass)

Computes the set of instances of the given EClass (including its sub-types).

This method is similar to getAllInstances(EClass, boolean) with strict=false.

Parameters:

eClass - the EClass for which look for instances

Returns:

all the instances of the given EClass from the resource

getAllInstances

EList<EObject> getAllInstances(EClass eClass,
                               boolean strict)

Computes the set of instances of the given EClass.

Parameters:

eClass - the EClass for which look for instances

strict - true if the lookup searches for strict instances

Returns:

if true then the method returns only the strict instances of the given EClass, otherwise it also returns the instances of the sub-types of eClass.
