Example 1 with ObjectPool

use of io.grpc.internal.ObjectPool in project grpc-java by grpc.

the class InProcessServerTest method serverHoldsRefToScheduler.

@Test

            count++;
            return ses;
        }

        @Override
        public ScheduledExecutorService returnObject(Object returned) {
            count--;

        }
    }
    RefCountingObjectPool pool = new RefCountingObjectPool();
