Examples of org.apache.openjpa.conf.OpenJPAConfiguration

org.apache.openjpa.conf.OpenJPAConfiguration
Defines the properties necessary to configure runtime properties and connect to a data source. There is a 1-1 relation between a configuration and a {@link BrokerFactory}. All setter methods that take primitive parameters also have wrapper setter with the appropriate primitive wrapper. This is so the interface can be in accordance with the J2EE Connector Architecture. @author Marc Prud'hommeaux @author Abe White @see Configuration
