org.eclipse.persistence.mappings.DirectToFieldMapping

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. @see org.eclipse.persistence.mappings.converters.Converter @see org.eclipse.persistence.mappings.converters.ObjectTypeConverter @see org.eclipse.persistence.mappings.converters.TypeConversionConverter @see org.eclipse.persistence.mappings.converters.SerializedObjectConverter @author Sati @since TopLink/Java 1.0

     * INTERNAL:
     * Set the DatabaseField that will represent the key in a DirectMapMapping.
