All Implemented Interfaces:

Disposable, Initialisable, Lifecycle, LifecycleStateEnabled, Startable, Stoppable, MessageSource, Connectable, MessageReceiver

public abstract class TransactedPollingMessageReceiver
extends AbstractPollingMessageReceiver

The TransactedPollingMessageReceiver is an abstract receiver that handles polling and transaction management. Derived implementations of these class must be thread safe as several threads can be started at once for an improved throughput.
