      com.metamatrix.dqp.embedded.services.EmbeddedConfigurationService

All Implemented Interfaces:

ApplicationService, ClassLoaderManager, ConfigurationService

public class EmbeddedConfigurationService
extends EmbeddedBaseDQPService
implements ConfigurationService

A File based configuration service implementation Implementation notes - While loading the VDBs also keep track of Connector Bindings loaded separately - While loading the VDBs also keep track of Connector types loaded separately - The above list also should contain the list from server config file. - Onlu used get, save, delete of any configuration on public api
