DatabaseResources
abstract public class DatabaseResources extends DbQueryManager implements ResourceFinder,ResourceWriter(Code)
This class offers ResourceFinder and ResourceWriter capabilities for resources that are stored in a database. The relevant database is specified through a Datasource/code> instance at construction. While the table can be configured through the TABLE_RESOURCES configuration setting, the structure of the table is fixed. It can be installed with the install() method and removed with the remove() method. The latter will implicitely erase all the resources that have been stored in the database table. author:    Geert Bevin (gbevin[remove] at uwyn dot com) version:    $Revision: 3634 $ See Also:   com.uwyn.rife.resources.ResourceFinder since:    1.0
