Examples of org.apache.camel.impl.EventDrivenPollingConsumer

org.apache.camel.impl.EventDrivenPollingConsumer
A default implementation of the {@link org.apache.camel.PollingConsumer} which uses the normalasynchronous consumer mechanism along with a {@link BlockingQueue} to allowthe caller to pull messages on demand. @version
