所有已实现的接口:

ExporterListener

public class InjvmExporterListener
extends ExporterListenerAdapter

The InjvmExporterListener class is an implementation of the ExporterListenerAdapter abstract class,

which is used to listen for changes to the InjvmExporter instances.

It maintains two ConcurrentHashMaps, one to keep track of the ExporterChangeListeners registered for each service,

and another to keep track of the currently exported services and their associated Exporter instances.

It overrides the exported and unexported methods to add or remove the corresponding Exporter instances to/from

the exporters ConcurrentHashMap, and to notify all registered ExporterChangeListeners of the change.

It also provides methods to add or remove ExporterChangeListeners for a specific service, and to retrieve the

currently exported Exporter instance for a given service.
