public class EISDirectMapping
extends AbstractDirectMapping
implements EISMapping

EIS Direct Mappings map a simple Java attribute to and from an EIS Record according to its descriptor's record type.

Record Type	Description
Indexed	Ordered collection of record elements. The indexed record EIS format enables Java class attribute values to be retreived by position or index.
Mapped	Key-value map based representation of record elements. The mapped record EIS format enables Java class attribute values to be retreived by an object key.
XML	Record/Map representation of an XML DOM element.

writeValueIntoRow

protected void writeValueIntoRow(org.eclipse.persistence.internal.sessions.AbstractRecord row,
                                 org.eclipse.persistence.internal.helper.DatabaseField field,
                                 java.lang.Object fieldValue)

Description copied from class: AbstractColumnMapping

INTERNAL:

Specified by:
