All Implemented Interfaces:

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.

Oracle TopLink 10g Release 2 (10.1.3)

Method Detail

isEISMapping

public boolean isEISMapping()

INTERNAL:

Overrides:

isEISMapping in class DatabaseMapping

setXPath

public void setXPath(java.lang.String xpathString)

Set the Mapping field name attribute to the given XPath String.

Parameters:

xpathString - String

getXPath

public java.lang.String getXPath()

Get the XPath String associated with this Mapping

Returns:

String the XPath String associated with this Mapping

setFieldName

public void setFieldName(java.lang.String fieldName)

PUBLIC: Set the field name in the mapping.

writeValueIntoRow

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

Specified by:

writeValueIntoRow in class AbstractDirectMapping

writeFromObjectIntoRow

public void writeFromObjectIntoRow(java.lang.Object object,
                                   org.eclipse.persistence.internal.sessions.AbstractRecord row,
                                   org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: We override this method in order to set the session on the record if the data format is XML. Get a value from the object and set that in the respective field of the row.

Overrides:

writeFromObjectIntoRow in class AbstractDirectMapping
