public class DirectMapMapping
extends DirectCollectionMapping
implements MapComponentMapping

Mapping for a collection of key-value pairs. The key and value must be simple types (String, Number, Date, etc.) and stored in a single table along with a foreign key to the source object. A converter can be used on the key and value if the desired object types do not match the data types.
