Interface IExternalPropertyManager

  • public interface IExternalPropertyManager
    Metadata external properties manager.

    Back references are automatically managed if EClass feature is annotated with #EXTERNAL_PROPERTY_ANNOTATION annotation.

    Information about external properties should be persisted. So it is not lost after application shutdown.

      • getOwner

        <T extends org.eclipse.emf.ecore.EObject> T getOwner​(org.eclipse.emf.ecore.EObject referenceObject,
                                                     Class<T> ownerType)
        Returns owner for given object.
        Parameters:
        referenceObject - the object to get owner for (not null)
        ownerType - the owner type (not null)
        Returns:
        the owner object for what back reference was registered or null if there is no back reference.

      • getReference

        org.eclipse.emf.ecore.EReference getReference​(org.eclipse.emf.ecore.EObject referenceObject)
        Returns reference which holds reference to external property
        Parameters:
        referenceObject - the object to get owner for (not null)
        Returns:
        the owner reference for what back reference object was registered or null if there is no back reference.

      • registerExternalProperty

        void registerExternalProperty​(org.eclipse.emf.ecore.EObject owner,
                              org.eclipse.emf.ecore.EReference reference,
                              org.eclipse.emf.ecore.EObject externalProperty)
        Registers back reference to owner from referenceObject. You can get owner object for referenceObject calling #getOwner(EObject). Reference object can have only one owner object. Consequent calls change owner to last called value.
        Parameters:
        owner - the owner object (not null)
        reference - the object feature which holds reference to external property (not null)
        externalProperty - the referenced object, can be proxy (not null)

      • unregisterExternalProperty

        void unregisterExternalProperty​(org.eclipse.emf.ecore.EObject externalProperty)
        Unregisters back reference from referenceObject.
        Parameters:
        externalProperty - the referenced object, can be proxy (not null)

      • unregisterExternalProperty

        void unregisterExternalProperty​(org.eclipse.emf.common.util.URI deassociatedUri)
        Unregisters back reference from referenceObject by URI.
        Parameters:
        deassociatedUri - Usually deassociated objects lack the resource, so normal resolving won't work for them. So one need to supply the URI of the object being just removed.
