Interface MapComponentMapping

All Known Subinterfaces:

MapKeyMapping

All Known Implementing Classes:

AbstractDirectMapping, AggregateCollectionMapping, AggregateObjectMapping, DirectMapMapping, DirectToFieldMapping, DirectToXMLTypeMapping, EISDirectMapping, ManyToManyMapping, ManyToOneMapping, OneToManyMapping, OneToOneMapping, UnidirectionalOneToManyMapping, XMLBinaryDataMapping, XMLDirectMapping, XMLFragmentMapping

public interface MapComponentMapping

A MapComponentMapping is any mapping that can be used as the key or the value in a mapping that uses a MappedKeyMapContainerPolicy. This interface is generally implemented by mappings that provide the value in a mapping to a Map. Mappings that provide the key generally implement sub-interface MapKeyMapping
