Examples of org.apache.qpid.qmf2.common.NotifierWrapper

org.apache.qpid.qmf2.console.Console
Implementation of QmfEventListener that wraps a Notifier instance. This class populates the WorkItem queue then invokes the Notifier's indication() method to notify clients of available data.
This approach allows us to support two separate asynchronous notification APIs without too much effort. @author Fraser Adams
