      Modifier and Type Method Description
      protected static void clearAllBreakpoints()  
      static boolean isDebugMode()
      Returns current debug mode.
      Holds lazy initialized internal reference to improve performance.
      Therefore you can't change System property "mvel.debugger" after isDebugMode is called at least once.

      To update debug mode at runtime use setDebugMode(boolean)
      static void receiveBreakpoints()
      Notify remote debugger that runtime is ready to get latest breakpoint information
      protected static void registerBreakpoint​(java.lang.String sourceName, int lineNumber)  
      protected static void removeBreakpoint​(java.lang.String sourceName, int lineNumber)  
      static void setDebugMode​(boolean b)
      Sets debug mode on/off.
      Updates local MVELDebugHandler property and System property "mvel.debugger"

      There's no need to ever call this method unless you write junit tests!
      protected static void setOnBreakReturn​(int value)

      • isDebugMode

        public static boolean isDebugMode()
        Returns current debug mode.
        Holds lazy initialized internal reference to improve performance.
        Therefore you can't change System property "mvel.debugger" after isDebugMode is called at least once.

        To update debug mode at runtime use setDebugMode(boolean)
        Returns:
        true if debug mode is enabled.

      • setDebugMode

        public static void setDebugMode​(boolean b)
        Sets debug mode on/off.
        Updates local MVELDebugHandler property and System property "mvel.debugger"

        There's no need to ever call this method unless you write junit tests!
        Parameters:
        b - is Debug enabled?
