  • Method Details

    • checkPort

      public final String checkPort() throws Exception
      Description copied from class: PortMonitor
      Checks the port. This may take arbitrarily long to complete, and any timeout should be provided externally and call the cancel method. If any error occurs, must throw an exception.
      Specified by:
      checkPort in class PortMonitor
      the message indicating success
      See Also:
    • cancel

      public void cancel()
      Description copied from class: PortMonitor

      Cancels this port method on a best effort basis. This will not necessarily cause the checkPort method to return immediately. This should only be used once the result of checkPort is no longer relevant, such as after a timeout. Some monitors may still perform their task arbitrarily long after cancel has been called.

      It is critical that subclass implementations of this method not block in any way.
