Graceful

Enclosing interface:

Graceful
```
public abstract static class Graceful.Shutdown
extends java.lang.Object
implements Graceful
```
A utility class to assist implementing the Graceful interface. The isShutdownDone() method should be implemented to check if the CompletableFuture returned by shutdown() should be completed or not. The check() method should be called when any state is changed which may complete the shutdown.

    Description copied from interface: Graceful
    
    Shutdown the component. When this method returns, the component should not accept any new load.
    
    Specified by:
    
    shutdown in interface Graceful
    
    Returns:
    
    A future that is completed once all load on the component is completed
  - isShutdown
```
public boolean isShutdown()
```
    Specified by:
    
    isShutdown in interface Graceful
    
    Returns:
    
    True if Graceful.shutdown() has been called.
  - check
```
public void check()
```
    This method should be called whenever the components state has been updated. If shutdown() has been called, then isShutdownDone() is called by this method and if it returns true then the Future returned by shutdown() is completed.
  - cancel
```
public void cancel()
```
  - isShutdownDone
```
public abstract boolean isShutdownDone()
```
    Returns:
    
    True if the component is shutdown and has no remaining load.
