Interface IElementDeltaBuilder

All Known Implementing Classes:
ElementDelta.Builder
public interface IElementDeltaBuilder
Builds an IElementDelta tree based on elementary changes.

Note that, despite having a dependency on IResourceDelta and IMarkerDelta, this interface can be used even when org.eclipse.core.resources bundle is not available. This is based on the "outward impression" of late resolution of symbolic references a JVM must provide according to the JVMS.

      IElementDeltaBuilder added(IElement element, long flags)
      Informs this builder that an element has been added.
      Parameters:
      element - the added element (not null)

      this builder

    • removed

      default IElementDeltaBuilder removed(IElement element)
      Has the same effect as removed(element, 0).
      Parameters:
      element - the removed element (not null)

    • removed

      IElementDeltaBuilder removed(IElement element, long flags)
      Informs this builder that an element has been removed.
      Parameters:
      element - the removed element (not null)

      Returns:
      this builder

    • changed

      IElementDeltaBuilder changed(IElement element, long flags)
      Informs this builder that an element has been changed.
      Parameters:
      element - the changed element (not null)
      flags - delta flags
      Returns:
      this builder

    • movedFrom

      IElementDeltaBuilder movedFrom(IElement movedFromElement, IElement movedToElement)
      Informs this builder that an element has been removed as it has moved to a new location.
      Parameters:
      movedFromElement - the element before it was moved to its current location (not null)
      movedToElement - the element in its new location (not null)
      Returns:
      this builder

    • movedTo

      IElementDeltaBuilder movedTo(IElement movedToElement, IElement movedFromElement)
      Informs this builder that an element has been added as it has moved from an old location.
      Parameters:
      movedToElement - the element in its new location (not null)
      movedFromElement - the element before it was moved to its current location (not null)
      Returns:
      this builder

    • markersChanged

      IElementDeltaBuilder markersChanged(IElement element, org.eclipse.core.resources.IMarkerDelta[] markerDeltas)
      Informs this builder about changes to markers on the given element's corresponding resource.
      Parameters:
      element - the element with changed markers (not null)
      markerDeltas - the marker deltas for the element (not null, not empty)
      Returns:
      this builder

    • addResourceDelta

      IElementDeltaBuilder addResourceDelta(IElement element, org.eclipse.core.resources.IResourceDelta resourceDelta)
      Informs this builder about changes to children of the given element's corresponding resource that cannot be described in terms of element deltas.
      Parameters:
      element - the element with a resource change (not null)
      resourceDelta - the resource delta for the element (not null)
      Returns:
      this builder

    • getDelta

      IElementDelta getDelta()
      Returns the root of the built delta tree. The delta tree describes the net result of all changes reported to this builder up to now. There is no requirement for the returned delta object to reflect subsequent changes reported to this builder; a new instance may be returned each time this method is invoked.
      Returns:
      the root of the built delta tree, or null if none
