      • configureAnnotation

        void configureAnnotation​(AnnotationNode an)
      • invalidateCallSites

      • getInvokeSpecialHandle

        Object getInvokeSpecialHandle​(Method m,
                                      Object receiver)
        Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead
        Returns:
        null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call
      • invokeHandle

        Object invokeHandle​(Object handle,

      • getVersion

        int getVersion()
        Gives the version the plugin is made for

                                      Class<?> callerClass)
        Check whether invoking AccessibleObject.setAccessible(boolean) on the accessible object will be completed successfully
        Parameters:
        accessibleObject - the accessible object to check
        callerClass - the callerClass to invoke setAccessible
        Returns:
