      protected Default(MethodDescription instrumentedMethod, List<? extends TypeDescription> initialTypes, List<? extends TypeDescription> preMethodTypes, List<? extends TypeDescription> postMethodTypes)
      Creates a new default meta data handler that recomputes the space requirements of an instrumented method.
      Parameters:
      instrumentedMethod - The instrumented method.
      initialTypes - A list of virtual method arguments that are explicitly added before any code execution.
      preMethodTypes - A list of virtual method arguments that are available before the instrumented method is executed.
      postMethodTypes - A list of virtual method arguments that are available after the instrumented method has completed.

      protected static Advice.MethodSizeHandler.ForInstrumentedMethod of(MethodDescription instrumentedMethod, List<? extends TypeDescription> initialTypes, List<? extends TypeDescription> preMethodTypes, List<? extends TypeDescription> postMethodTypes, boolean copyArguments, int writerFlags)
      Creates a method size handler applicable for the given instrumented method.
      Parameters:
      instrumentedMethod - The instrumented method.
      initialTypes - A list of virtual method arguments that are explicitly added before any code execution.
      preMethodTypes - A list of virtual method arguments that are available before the instrumented method is executed.
      postMethodTypes - A list of virtual method arguments that are available after the instrumented method has completed.
      copyArguments - true if the original arguments are copied before invoking the instrumented method.
      writerFlags - The flags supplied to the ASM class writer.
      Returns:
      An appropriate method size handler.

    • bindEnter

      public Advice.MethodSizeHandler.ForAdvice bindEnter(MethodDescription.TypeToken typeToken)

      Parameters:
      typeToken - The type token representing the enter advice.
      Returns:
      A method size handler for the enter advice.

    • requireStackSize
