public void close()
```
    When no longer needed, close should be called to free resources.

    close in interface AutoCloseable
  - addListener
```
public void addListener(L listener,
                        boolean synchronous)
                 throws IllegalStateException
```
    Adds a listener.
    
    Parameters:
    
    synchronous - When true, listener will be called synchronously by the I/O thread; when false, listener will be called asynchronously by a separate thread.
    
    Throws:
    
    IllegalStateException - If the listener has already been added
  - removeListener
```
public boolean removeListener(L listener)
```
    Removes a listener.
    
    Returns:
    
    true if the listener was found
  - enqueueEvent
```
public Future<?> enqueueEvent(ConcurrentListenerManager.Event<? super L> event)
```
    Enqueues a new event to all listener event queues. If the caller needs to wait until the event has been handled by each of the listeners, then call .get() on the returned Future.
