Examples of com.google.common.util.concurrent.Service.start()

com.google.common.util.concurrent.Service.start()
If the service state is {@link State#NEW}, this initiates service startup and returns immediately. If the service has already been started, this method returns immediately without taking action. A stopped service may not be restarted. @return a future for the startup result, regardless of whether this callinitiated startup. Calling {@link ListenableFuture#get} will blockuntil the service has finished starting, and returns one of {@link State#RUNNING}, {@link State#STOPPING} or {@link State#TERMINATED}. If the service fails to start, {@link ListenableFuture#get} will throw an{@link ExecutionException}, and the service's state will be {@link State#FAILED}. If it has already finished starting, {@link ListenableFuture#get} returns immediately. Cancelling the returnedfuture is unsupported and always returns {@code false}.
