- All Implemented Interfaces:
Serializable
,Cloneable
,MapComponentMapping
,MapKeyMapping
- Direct Known Subclasses:
DirectToFieldMapping
,EISDirectMapping
,XMLDirectMapping
Purpose: Maps an attribute to the corresponding database field type.
The list of field types that are supported by EclipseLink's direct to field mapping
is dependent on the relational database being used.
A converter can be used to convert between the object and data type if they do not match.
