Description copied from interface: GracefulShutdownHook

Execute shutdown tasks for the service that implements this interface.

Warning:

• This method is called from another thread so the class that implements GracefulShutdownHook must be thread-safe.
• The server shutdown is waiting for this method call to complete. Blocking this method will block the server shutdown!

Specified by:

doGracefulShutdown in interface GracefulShutdownHook

Throws:

Exception

triggerShutdown

protected void triggerShutdown()

Overrides:

triggerShutdown in class com.google.common.util.concurrent.AbstractExecutionThreadService
