Class DirectToFieldMapping

java.lang.Object

oracle.toplink.essentials.mappings.DatabaseMapping

oracle.toplink.essentials.mappings.foundation.AbstractDirectMapping

oracle.toplink.essentials.mappings.DirectToFieldMapping

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, RelationalMapping

public class DirectToFieldMapping
extends AbstractDirectMapping
implements RelationalMapping

Purpose: Maps an attribute to the corresponding database field type. The list of field types that are supported by TopLink'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.

Since:

TopLink/Java 1.0
