  • Method Details

    • resourceChanged

      protected void resourceChanged(org.eclipse.core.resources.IResourceChangeEvent event)
      Notifies that the outline page is affected in some way by the given resource change event.

      Note: This method may be called in any thread. The event object (and the delta within it) is valid only for the duration of the invocation of this method.

      This implementation schedules a full refresh of the outline page's tree viewer in the UI thread.

      Specified by:
      resourceChanged in class ResourceChangeListenerContribution
      Parameters:
      event - never null

    • affects

      protected boolean affects(org.eclipse.core.resources.IResourceChangeEvent event, Object inputElement)
      Returns whether the given resource change event affects the outline's input element.

      This implementation checks whether the given resource change event affects problem markers attached to the corresponding resource of the input element. It uses hasProblemMarkerChanges(IResourceDelta) to check the corresponding resource delta. The corresponding resource is determined as follows:

      • If the input element is an IResource, the corresponding resource is the element itself.
      • Otherwise, if the input element could be adapted to an IElement through the content adapter, the corresponding resource is obtained via Elements.getResource(IElement).
      • Otherwise, the input element is adapted to an IResource via ResourceUtil.getResource(Object).
      Specified by:
      affects in class ResourceChangeListenerContribution
      Parameters:
      event - never null
      inputElement - never null
      Returns:
      true if the given resource change event affects the outline's input element, and false otherwise

    • hasProblemMarkerChanges

      protected boolean hasProblemMarkerChanges(org.eclipse.core.resources.IResourceDelta delta)
      Returns whether the given resource delta describes problem marker changes.
      Parameters:
      delta - the resource delta (never null)
      Returns:
      true if the given resource delta describes problem marker changes, and false otherwise

    • getContentAdapter

      protected IContentAdapter getContentAdapter()
      Returns the installed content adapter, or a NullContentAdapter if none.

      This implementation returns the content adapter provided by the outline page, if the outline page is an IContentAdapterProvider.

      Returns:
      an IContentAdapter (never null)
