    • Dependence

      public Dependence(PDGNode src, PDGNode dst)
      Creates a new object that represents a dependence edge. This method is not intended to be invoked by clients.
      Parameters:
      src - the source node
      dst - the destination node

  • Method Details

    • isDependence

      public boolean isDependence()
      Tests if this edge represents a dependence.
      Specified by:
      isDependence in interface DependencyGraphEdge
      Returns:
      true if this is a dependence edge, otherwise false
