    Modifier and Type | Method | Description
    --- | --- | ---
    `Acceptor.AcceptorState` | `getState()` |
    `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.
    `void` | `run()` |
    `void` | `stop​(int waitSeconds)` | Signals the Acceptor to stop, optionally waiting for that stop process to complete before returning.

- - ### Field Detail

    - #### state

          protected volatile Acceptor.AcceptorState state

  - ### Constructor Detail

    - #### Acceptor

          public Acceptor​(AbstractEndpoint<?,​U> endpoint)

  - ### Method Detail

    - #### getState

          public final Acceptor.AcceptorState getState()

    - #### run

          public void run()

      Specified by:
        `run` in interface `Runnable`

    - #### stop

          public void stop​(int waitSeconds)

      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.

    - #### 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
