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
