Examples with TerminateCallback org.apache.bookkeeper.mledger.AsyncCallbacks.TerminateCallback used on opensource projects

Example 1 with TerminateCallback

use of org.apache.bookkeeper.mledger.AsyncCallbacks.TerminateCallback in project incubator-pulsar by apache.

the class PersistentTopic method terminate.

public CompletableFuture<MessageId> terminate() {
    CompletableFuture<MessageId> future = new CompletableFuture<>();
    ledger.asyncTerminate(new TerminateCallback() {

        @Override
        public void terminateComplete(Position lastCommittedPosition, Object ctx) {
            producers.forEach(Producer::disconnect);
            subscriptions.forEach((name, sub) -> sub.topicTerminated());
            PositionImpl lastPosition = (PositionImpl) lastCommittedPosition;
            MessageId messageId = new MessageIdImpl(lastPosition.getLedgerId(), lastPosition.getEntryId(), -1);
            log.info("[{}] Topic terminated at {}", getName(), messageId);
            future.complete(messageId);
        }

        @Override
        public void terminateFailed(ManagedLedgerException exception, Object ctx) {
            future.completeExceptionally(exception);
        }
    }, null);
    return future;
}

Example 2 with TerminateCallback

use of org.apache.bookkeeper.mledger.AsyncCallbacks.TerminateCallback in project incubator-pulsar by apache.

the class ManagedLedgerImpl method terminate.

@Override
public Position terminate() throws InterruptedException, ManagedLedgerException {
    final CountDownLatch counter = new CountDownLatch(1);
    class Result {

        Position lastPosition = null;

        ManagedLedgerException exception = null;
    }
    final Result result = new Result();
    asyncTerminate(new TerminateCallback() {

        @Override
        public void terminateComplete(Position lastPosition, Object ctx) {
            result.lastPosition = lastPosition;
            counter.countDown();
        }

        @Override
        public void terminateFailed(ManagedLedgerException exception, Object ctx) {
            result.exception = exception;
            counter.countDown();
        }
    }, null);
    if (!counter.await(AsyncOperationTimeoutSeconds, TimeUnit.SECONDS)) {
        throw new ManagedLedgerException("Timeout during managed ledger terminate");
    }
    if (result.exception != null) {
        log.error("[{}] Error terminating managed ledger", name, result.exception);
        throw result.exception;
    }
    return result.lastPosition;
}
