public abstract class MessageProcessorPollingOverride
extends Object

Extension point to hook extra functionality to a message processor polling component. Implementation registered with Poll will be called on each execution to provide an interceptor which will then be called on several execution checkpoints. Note that while this class should be threadsafe, interceptors returned will be scoped on a single execution, and hence may carry state.
