Interface MappingContext<E extends PersistentEntity<?,P>,P extends PersistentProperty<P>>

All Known Implementing Classes:

AbstractMappingContext

public interface MappingContext<E extends PersistentEntity<?,P>,P extends PersistentProperty<P>>

This interface defines the overall context including all known PersistentEntity instances and methods to obtain instances on demand. it is used internally to establish associations between entities and also at runtime to obtain entities by name.
