com.volantis.mcs.repository.RepositoryEnumeration
This interface should be implemented by those classes which represent a set of results from a database query. It is very similar to the standard java.util.Enumeration and java.util.Iterator class except that the methods can all throw RepositoryExceptions and it has an extra method, close, which must be called when the results have been read. @volantis-api-include-in PublicAPI @volantis-api-include-in ProfessionalServicesAPI @volantis-api-include-in InternalAPI @mock.generate
