    • JavaElementDelta

      public JavaElementDelta​(IJavaElement element)
      Creates the root delta. To create the nested delta hierarchies use the following convenience methods. The root delta can be created at any level (for example: project, package root, package fragment...).

      • changed(IJavaElement)
      • moved(IJavaElement, IJavaElement)
      • removed(IJavaElement)
