Class FlatEObjectImpl

java.lang.Object

BasicNotifierImpl

org.eclipse.emf.ecore.impl.EObjectImpl

org.eclipse.emf.ecore.impl.FlatEObjectImpl

All Implemented Interfaces:

EObject, InternalEObject

public class FlatEObjectImpl
extends EObjectImpl

An implementation of the model object 'EObject'. This implementation flattens the fields for storing the eProxyURI, the eContents, and the eCrossReferences, which in EObjectImpl are stored in the properties holder. This reduces the likelihood of needing to allocate a properties holder and speeds up the access to these fields.

Constructor Detail

FlatEObjectImpl

protected FlatEObjectImpl()

Creates an EObject that is faster and more space efficient for the case where eSetProxyURI(URI), eContents(), eCrossReferences() are expected to be frequently used.

Method Detail

eProperties

protected BasicEObjectImpl.EPropertiesHolder eProperties()

Overrides:

eProperties in class EObjectImpl

eIsProxy

public boolean eIsProxy()

Description copied from interface: EObject

Indicates whether this object is a proxy.

A proxy is an object that is defined in a Resource that has not been loaded. An object may be a proxy either because proxy resolution was disabled when the object was accessed (see EObject.eGet(EStructuralFeature,boolean)) or because proxy resolution failed.

Specified by:

eIsProxy in interface EObject

Overrides:

eIsProxy in class EObjectImpl

Returns:

true if this object is a proxy or false, otherwise.

See Also:

Resource.unload(), EcoreUtil.resolve(EObject, org.eclipse.emf.ecore.resource.ResourceSet)

eProxyURI

public URI eProxyURI()

Description copied from interface: InternalEObject

Returns the proxy URI of this object. It can be used to resolve to the actual object.

Specified by:

eProxyURI in interface InternalEObject

Overrides:

eProxyURI in class BasicEObjectImpl

Returns:

the proxy URI of this object.

See Also:

EcoreUtil.resolve(EObject, org.eclipse.emf.ecore.resource.ResourceSet), Resource.unload()

eSetProxyURI

public void eSetProxyURI(URI uri)

Description copied from interface: InternalEObject

Set the proxy URI of this object. It will be used to resolve to the actual object.

Specified by:

eSetProxyURI in interface InternalEObject

Overrides:

eSetProxyURI in class EObjectImpl

Parameters:

uri - the URI.

See Also:

EcoreUtil.resolve(EObject, org.eclipse.emf.ecore.resource.ResourceSet), Resource.unload()

eContents

public <any> eContents()

Description copied from interface: EObject

Returns a list view of the content objects; it is unmodifiable.

This will be the list of EObjects determined by the contents of the containment features of this object's meta class. Objects can, indirectly, be removed and will change to reflect container changes. The implicit tree of contents is also directly available.

Specified by:

eContents in interface EObject

Overrides:

eContents in class BasicEObjectImpl

Returns:

a list view of the content objects.

See Also:

EObject.eContainer(), EClass.getEAllContainments(), EObject.eGet(EStructuralFeature), EcoreUtil.remove(EObject), EObject.eAllContents()

eCrossReferences

public <any> eCrossReferences()

Description copied from interface: EObject

Returns a list view of the cross referenced objects; it is unmodifiable.

This will be the list of EObjects determined by the contents of the reference features of this object's meta class, excluding containment features and their opposites. The cross reference list's iterator will be of type EContentsEList.FeatureIterator, for efficient determination of the feature of each cross reference in the list, e.g.,

  for (EContentsEList.FeatureIterator featureIterator = 
        (EContentsEList.FeatureIterator)eObject.eCrossReferences().iterator();
       featureIterator.hasNext(); )
  {
    EObject eObject = (EObject)featureIterator.next();
    EReference eReference = (EReference)featureIterator.feature();
    ...
  }

Specified by:

eCrossReferences in interface EObject

Overrides:

eCrossReferences in class BasicEObjectImpl

Returns:

a list view of the cross referenced objects.
