public class StandardServiceAdapter

extends AbstractService

implements ServiceAdapter

StandardServiceAdapter is a base class for providing an interface for use by clients which provides access to one or more other Services not known to those clients. In other words, a client will invoke a business method on a ServiceAdapter, which will then access other Services (not known to the client) to fulfull the request. This class can be extended to add business-level methods specific to the Service it adapts.

It can also be used by ServiceConnectors to define dependencies on other required Services.
