Class ServiceDispatcher

java.lang.Object

nl.nn.adapterframework.receivers.ServiceDispatcher

public class ServiceDispatcher
extends Object

Singleton class that knows about the ServiceListeners that are active.
This class is to be used as a facade for different services that implement the ServiceClient interface.
This class is exposed as a webservice, to be able to provide a single point of entry to all adapters that have a ServiceListener as a IReceiver.
