Example 1 with ConnectionPoolWaitQueueEnteredEvent

use of com.mongodb.event.ConnectionPoolWaitQueueEnteredEvent in project mongo-java-driver by mongodb.

the class DefaultConnectionPool method get.

@Override

    try {
        if (waitQueueSize.incrementAndGet() > settings.getMaxWaitQueueSize()) {
            throw createWaitQueueFullException();
