      protected void generateMopCalls(LinkedList<MethodNode> methods, boolean useThis)
      Generates a Meta Object Protocol method that is used to call a non-public method or to make a call to super.
      Parameters:
      methods - list of methods a MOP call method should be generated for
      useThis - indicates if "this" should be used for the name and call

    • getMopMethodName

      public static String getMopMethodName(MethodNode method, boolean useThis)
      Creates a MOP method name from a method.
      Parameters:
      method - the method to be called by the mop method
      useThis - if true, then it is a call on "this", "super" else
      Returns:
      the mop method name

    • isMopMethod

      public static boolean isMopMethod(String methodName)
      Determines if a method is a MOP method. This is done by the method name. If the name starts with "this$" or "super$" but does not contain "$dist$", then it is an MOP method.
      Parameters:
      methodName - name of the method to test
      Returns:
      true if the method is a MOP method

    • equalParameterTypes

      @Deprecated public static boolean equalParameterTypes(Parameter[] p1, Parameter[] p2)
      Deprecated.
      Use ParameterUtils.parametersEqual(Parameter[], Parameter[]) instead
      Checks if two parameter arrays are equal.
      Parameters:
      p1 - first parameter array
      p2 - second parameter array
      Returns:
      true if parameters are equal
