Method Detail

createDelegatingProxy

public static java.lang.Object createDelegatingProxy(java.lang.String type,
                                                     ServiceModel serviceModel,
                                                     java.lang.String delegationMethodName,
                                                     ServicePoint servicePoint)

Creates a class that implements the service interface. Implements a private synchronized method, _service(), that constructs the service as needed, and has each service interface method re-invoke on _service(). Adds a toString() method if the service interface does not define toString().

createOuterProxy

public static RegistryShutdownListener createOuterProxy(java.lang.Object delegate,
                                                        ServicePoint servicePoint)

Constructs an outer proxy (for the threaded or pooled service). The outer proxy listens to the shutdown coordinator, and delegates from the declared interface (which may in fact be a bean) to the service interface.

The outer proxy is a RegistryShutdownListener; it can be registered for notifications and will respond by throwing an exception when service methods are invoked.

Parameters:

delegate - An object, implementing the service interface, that the proxy should delegate to.

servicePoint - for which the proxy is being constructed
