    Modifier and Type
    Method
    Description
    protected static final 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 final void
    registerBreakpoint(String sourceName, int lineNumber)
     
    protected static final void
    removeBreakpoint(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 final 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"

      Parameters:
      b - is Debug enabled?
