    • Method Detail

      • installDerivedState

        void installDerivedState​(org.eclipse.emf.ecore.resource.Resource resource,
                         org.eclipse.emf.common.notify.Notification event,
                         boolean preLinkingPhase)
        callback to do modifications when and before getContents is called the first time on a resource.
        Parameters:
        resource - the resource to install derived state on
        event - the model change event, can be null.
        preLinkingPhase - whether the call is done in a pre-linking phase. During this phase clients may not do linking which relies on indexed information, because the index might not be fully computed yet.

      • discardDerivedState

        void discardDerivedState​(org.eclipse.emf.ecore.resource.Resource resource,
                         org.eclipse.emf.common.notify.Notification event)
        is called when the resource is updated. Clients should revert all the changes they did during #installDerivedState(Resource, boolean)
        Parameters:
        resource - the resource to discard derived state on
        event - the model change event, can be null.

      • isAffected

        boolean isAffected​(org.eclipse.emf.ecore.resource.Resource resource,
                   org.eclipse.emf.common.notify.Notification event)
        Checks if model change event affects derived state of the given resource.
        Parameters:
        resource - the resource to install derived state on
        event - the model change event.
        Returns:
        true if derived state should be recomputed for the given resource, false if this model changes doesn't affect derived state.
