`abstract boolean`	`isTerminated()` Returns whether the server is terminated.
`abstract Server`	`shutdown()` Initiates an orderly shutdown in which preexisting calls continue but new calls are rejected.

public Server()
```
- Method Detail
  - start
```
public abstract Server start()
                      throws IOException
```
    Bind and start the server. After this call returns, clients may begin connecting to the listening socket(s).
    
    Returns:
    
    this object
    
    Throws:
    
    IllegalStateException - if already started or shut down
    
    IOException - if unable to bind
    
    Since:
    
    1.0.0
  - getPort
```
public int getPort()
```
    Returns the port number the server is listening on. This can return -1 if there is no actual port or the result otherwise does not make sense. Result is undefined after the server is terminated. If there are multiple possible ports, this will return one arbitrarily. Implementations are encouraged to return the same port on each call.
    
    Throws:
    
    IllegalStateException - if the server has not yet been started.
    
    Since:
    
    1.0.0

    getListenSockets()
  - getListenSockets
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/5332")
public List<? extends SocketAddress> getListenSockets()
```
    Returns a list of listening sockets for this server. May be different than the originally requested sockets (e.g. listening on port '0' may end up listening on a different port). The list is unmodifiable.
    
    Throws:
    
    IllegalStateException - if the server has not yet been started.
    
    Since:
    
    1.19.0
  - getServices
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2222")
public List<ServerServiceDefinition> getServices()
```
    Returns all services registered with the server, or an empty list if not supported by the implementation.
    
    Since:
    
    1.1.0
  - getImmutableServices
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2222")
public List<ServerServiceDefinition> getImmutableServices()
```
    Returns immutable services registered with the server, or an empty list if not supported by the implementation.
    
    Since:
    
    1.1.0
  - getMutableServices
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2222")
public List<ServerServiceDefinition> getMutableServices()
```
    Returns mutable services registered with the server, or an empty list if not supported by the implementation.
    
    Since:
    
    1.1.0
  - shutdown
```
public abstract Server shutdown()
```
    Initiates an orderly shutdown in which preexisting calls continue but new calls are rejected. After this call returns, this server has released the listening socket(s) and may be reused by another server.
    Note that this method will not wait for preexisting calls to finish before returning. awaitTermination() or awaitTermination(long, TimeUnit) needs to be called to wait for existing calls to finish.
    Calling this method before start() will shut down and terminate the server like normal, but prevents starting the server in the future.
    
    Returns:
    
    this object
    
    Since:
    
    1.0.0
  - shutdownNow
```
public abstract Server shutdownNow()
```
    Initiates a forceful shutdown in which preexisting and new calls are rejected. Although forceful, the shutdown process is still not instantaneous; isTerminated() will likely return false immediately after this method returns. After this call returns, this server has released the listening socket(s) and may be reused by another server.
    Calling this method before start() will shut down and terminate the server like normal, but prevents starting the server in the future.
    
    Returns:
    
    this object
    
    Since:
    
    1.0.0
  - isShutdown
```
public abstract boolean isShutdown()
```
    Returns whether the server is shutdown. Shutdown servers reject any new calls, but may still have some calls being processed.
    
    Since:
    
    1.0.0
    
    See Also:
    
    shutdown(), isTerminated()
  - isTerminated
```
public abstract boolean isTerminated()
```
    Returns whether the server is terminated. Terminated servers have no running calls and relevant resources released (like TCP connections).
    
    Since:
    
    1.0.0
    
    See Also:
    
    isShutdown()
  - awaitTermination
```
public abstract boolean awaitTermination(long timeout,
                                         TimeUnit unit)
                                  throws InterruptedException
```
    Waits for the server to become terminated, giving up if the timeout is reached.
    Calling this method before start() or shutdown() is permitted and does not change its behavior.
    
    Returns:
    
    whether the server is terminated, as would be done by isTerminated().
    
    Throws:
    
    InterruptedException
  - awaitTermination
```
public abstract void awaitTermination()
                               throws InterruptedException
```
    Waits for the server to become terminated.
    Calling this method before start() or shutdown() is permitted and does not change its behavior.
    
    Throws:
    
    InterruptedException
    
    Since:
    
    1.0.0
