EIS Transformation Mapping

A transformation EIS mapping lets you create a custom mapping, where one or more fields in an EIS record can be used to create the object to be stored in a Java class's attribute.

Table 56-8 summarizes the behavior of this mapping depending on the EIS record type you are using.

Table 56-8 EIS Transformation Mapping by EIS Record Type

EIS Record Type	Mapping Behavior
Indexed	.The field transformer adds data to the indexed record (you have access to the indexed record in the attribute transformer).
Mapped	.The field transformer adds data to the mapped record (you have access to the mapped record in the attribute transformer).
XML	.The field transformer adds data to the XML record (you have access to the XML record in the attribute transformer).

As Figure 56-12 illustrates, you configure the transformation mapping with an oracle.toplink.mappings.transformers.AttributeTransformer instance to perform the XML instance-to-Java attribute transformation at unmarshall time. In this example, the AttributeTransformer combines two XML text nodes into a single Java object.
