Examples of com.sun.sgs.service.DataService

com.sun.sgs.service.DataService
Provides facilities for services to manage access to shared, persistent objects. In addition to the methods provided by {@link DataManager}, this interface includes methods for an additional set of service bindings. These service bindings are intended to by used by services to support their needs to store objects persistently. The objects associated with service bindings are independent of the objects bound through methods defined on DataManager. Services should insure that they use unique names for service bindings by using their class or package name as the prefix for the name.
