- ## Method Details

  - ### getState

    public final Acceptor.AcceptorState getState()

  - ### run

    public void run()
    Specified by:
      `run` in interface `Runnable`

  - ### stop

    @Deprecated public void stop(int waitSeconds)
    Deprecated.
    Unused. Will be remove in Tomcat 11 onwards.
    Signals the Acceptor to stop, optionally waiting for that stop process to complete before returning. If a wait is requested and the stop does not complete in that time a warning will be logged.
    Parameters:
      `waitSeconds` - The time to wait in seconds. Use a value less than zero for no wait.

  - ### stopMillis

    public void stopMillis(int waitMilliseconds)

  - ### handleExceptionWithDelay

    protected int handleExceptionWithDelay(int currentErrorDelay)
    Handles exceptions where a delay is required to prevent a Thread from entering a tight loop which will consume CPU and may also trigger large amounts of logging. For example, this can happen if the ulimit for open files is reached.
    Parameters:
      `currentErrorDelay` - The current delay being applied on failure
    Returns:
      The delay to apply on the next failure
