public class DefaultPersistentEObject
extends MinimalEStoreEObjectImpl
implements PersistentEObject

The default implementation of a PersistentEObject.

This class extends MinimalEStoreEObjectImpl that delegates EStructuralFeature accesses to an underlying EStore that interacts with the database used to store the model.

DefaultPersistentEObjects is backend-agnostic, and is as an EMF-level element wrapper in all existing database implementations.

Defines the identifier of this PersistentEObject.

Specified by:

id in interface PersistentEObject

Parameters:

id - the identifier

isMapped

public boolean isMapped()

Description copied from interface: PersistentEObject

Returns whether this PersistentEObject is mapped to an entity stored in a database.

Specified by:

isMapped in interface PersistentEObject

Returns:

true if this PersistentEObject is mapped to an entity stored in a database

setMapped

public void setMapped(boolean mapped)

Description copied from interface: PersistentEObject

Defines whether this PersistentEObject is mapped to an entity stored in a database.

Specified by:

setMapped in interface PersistentEObject

Parameters:

mapped - true if this PersistentEObject is mapped, otherwise false

resource

@Nullable
public Resource.Internal resource()

Description copied from interface: PersistentEObject

Returns the resource that contains this PersistentEObject.

Specified by:

resource in interface PersistentEObject

Returns:

the containing resource

resource

public void resource(Resource.Internal resource)

Description copied from interface: PersistentEObject

Defines the resource that contains this PersistentEObject.

Specified by:

resource in interface PersistentEObject

Parameters:

resource - the containing resource

eContainer

public EObject eContainer()

Description copied from interface: org.eclipse.emf.ecore.EObject

Returns the containing object, or null.

An object is contained by another object if it appears in the contents of that object. The object will be contained by a containment feature of the containing object.

Specified by:

eContainer in interface EObject

Overrides:

eContainer in class BasicEObjectImpl

Returns:

the containing object.

EObject.eResource(), EcoreUtil.remove(EObject), EObject.eContainmentFeature(), EObject.eContainingFeature(), EcoreUtil.getRootContainer(EObject), EObject.eContents()

eResource

public Resource eResource()

Description copied from interface: org.eclipse.emf.ecore.EObject

Returns the containing resource, or null.

An object is contained in a resource if it, or one of it's containers, appears in the contents of that resource.

An object must be contained by a resource in order to be serialized.

Specified by:

eResource in interface EObject

Overrides:

eResource in class BasicEObjectImpl

Returns:

the containing resource.
