Examples of com.netflix.eventbus.impl.EventBusImpl$ConsumerQueueSupplier$ConsumerQueue

com.netflix.eventbus.impl.EventBusImpl
This is a stripped down version of {@link BlockingQueue} to only expose methods that are required by the{@link EventConsumer}. The intention of stripping down the functionality is to have more control over the queue implementation which in turn completely supplies the batching strategy. If the consumer starts using other methods of the {@link BlockingQueue} our batching may completely break. Using {@link BlockingQueue} willmean implementing methods that we never use.
