public class JPADSGenerator
extends java.lang.Object getDataSourceConfigFromJPAClass(String className) - generates configuration for JPA 1.0 data source. Processes only annotated classes (does not support entity mapping specified in external XML file). Class has to be annotated with one of these annotations: Entity, MappedSuperclass, Embeddable. generateFromPersistenceUnit (String persistenceUnitName) - generates configuration for JPA 2.0 data source for all entities mapped in specified persistence unit. This method requires JPA 2.0. Make sure you use JPA provider with JPA 2.0 implementation.dsTypeForJavaType method description for supported types.| Modifier and Type | Method and Description |
|---|---|
static java.util.Map | generateFromPersistenceUnit(java.lang.String persistenceUnitName) Generates data source configurations for all entities mapped in specified persistent unit. Works only with JPA 2.0 implementation. |
static java.util.Map | getDataSourceConfigFromJPAClass(java.lang.String className) Returns data source configuration for specified class. |
static java.util.Map | getDataSourceConfigFromJPAClass(java.lang.String className, boolean extended) Returns data source configuration for specified class. |
static java.util.Map | getDataSourceConfigFromMetamodel(java.lang.String className, EntityManager em) Returns data source configuration for specified class. Plural fields (one-to-many relations) will be generated. Works only with JPA 2.0 implementation. |
static java.util.Map | getDataSourceConfigFromMetamodel(java.lang.String className, EntityManager em, boolean generateRelations, boolean extended) Returns data source configuration for specified class. Works only with JPA 2.0 implementation. |
