public class DataStoreHelperMetaData extends java.lang.Object
This class provides metadata information for DataStoreHelpers. DataStoreHelperMetaData can be used to retrieve static information about the database and JDBC driver. Setter methods are provided only for the DataStoreHelper class to use in initializing the DataStoreHelperMetaData. The setter methods must never be used directly by the application.
