All Known Implementing Classes:

public interface ServiceAdapter

extends Service

ServiceAdapter is a Service that defines 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 interface can be extended to add business-level methods specific to the Service it adapts.

In addition, a ServiceAdapter may define dependencies on other required Services, which can enable a ServiceConnector to offer conditional support for the Service implemented by the ServiceAdapter.
