Class DefaultMarkerBehavior


  • public class DefaultMarkerBehavior
    extends java.lang.Object
    The default implementation for the DiagramBehavior behavior extension that controls how markers are handled in the editor. Clients may subclass to change the marker behavior; use DiagramBehavior.createMarkerBehavior() to return the instance that shall be used.
    Note that there is always a 1:1 relation with a DiagramBehavior.
    Since:
    0.9
    • Method Detail

      • initialize

        public void initialize()
        Initializes this marker behavior extension. The default implementation simply registers an adapter that updates the markers when EMF objects change.
      • getProblemIndicationAdapter

        public org.eclipse.emf.ecore.util.EContentAdapter getProblemIndicationAdapter()
        Returns the adapter that is installed for updating the markers.
        Returns:
        the problemIndicationAdapter
      • disableProblemIndicationUpdate

        public void disableProblemIndicationUpdate()
        Can be called to (temporarily) disable the marker update adapter, so that mass changes do not result in a bunch of notifications and cause performance penalties.
        See Also:
        enableProblemIndicationUpdate()
      • enableProblemIndicationUpdate

        public void enableProblemIndicationUpdate()
        Can be called to enable the marker update adapter again after it has been disabled with disableProblemIndicationUpdate(). The default implementation also triggers an update of the markers.
      • analyzeResourceProblems

        public org.eclipse.emf.common.util.Diagnostic analyzeResourceProblems​(org.eclipse.emf.ecore.resource.Resource resource,
                                                                              java.lang.Exception exception)
        Returns a diagnostic describing the errors and warnings listed in the resource and the specified exception (if any).
        Parameters:
        resource - the resource to analyze
        exception - forwarded as data object to the BasicDiagnostic
        Returns:
        a new Diagnostic for the given resource
      • dispose

        public void dispose()
        Called to dispose this instance when the editor is closed. The default implementation simply disables the marker update adapter and removes it from the resource set and clears its member variables.
