Field Detail

metamodelMap

private Map<String,javax.persistence.metamodel.Metamodel> metamodelMap

Map of Entity Metadata.

persistenceUnitMetadataMap

private Map<String,PersistenceUnitMetadata> persistenceUnitMetadataMap

Map of Persistence Unit Metadata.

logger

private static org.slf4j.Logger logger

The Constant log.

metaModelBuilder

private Map<String,MetaModelBuilder> metaModelBuilder

clazzToPuMap

private Map<String,List<String>> clazzToPuMap

Collection instance to hold clazz's full name to persistence unit mapping. Valid Assumption: 1 class can belong to 1 pu only. Reason is @table needs to give pu name!
