      name - mandatory label name, should be unique, or the method will throw an exception.
      Returns:
      the newly created label

      Returns:
      the newly created label

    • create

      IJavaLabel create()
      Create an unnamed label with no offset.
      Returns:
      the newly created label

    • getLabels

      List<IJavaLabel> getLabels()
      Get the list of labels defined by the factory.
      Returns:
      defined labels

    • recordTrampoline

      void recordTrampoline(int trampoAddr, int targetAddr)
      Record a trampoline relationship between two addresses.
      Parameters:
      trampoAddr - trampoline address
      targetAddr - target address

    • checkEquivalence

      boolean checkEquivalence(IJavaLabel label1, IJavaLabel label2)
      Determine whether two labels refer to equivalent locations.
      Parameters:
      label1 - first label
      label2 - second label
      Returns:
      true if the labels are equivalent
