Method Detail

shutdown

public abstract ManagedChannel shutdown()

Initiates an orderly shutdown in which preexisting calls continue but new calls are immediately cancelled.

isShutdown

public abstract boolean isShutdown()

Returns whether the channel is shutdown. Shutdown channels immediately cancel any new calls, but may still have some calls being processed.

See Also:

shutdown(), isTerminated()

isTerminated

public abstract boolean isTerminated()

Returns whether the channel is terminated. Terminated channels have no running calls and relevant resources released (like TCP connections).

See Also:

isShutdown()

shutdownNow

public abstract ManagedChannel shutdownNow()

Initiates a forceful shutdown in which preexisting and new calls are cancelled. Although forceful, the shutdown process is still not instantaneous; isTerminated() will likely return false immediately after this method returns.

awaitTermination

public abstract boolean awaitTermination(long timeout,
                                         TimeUnit unit)
                                  throws InterruptedException

Waits for the channel to become terminated, giving up if the timeout is reached.

Returns:

whether the channel is terminated, as would be done by isTerminated().

Throws:

InterruptedException
