# EIS Composite Direct Collection Mapping

An EIS composite direct collection mapping maps a collection of Java attributes directly to an EIS record according to its descriptor's record type, as shown in Table 56-3.

Table 56-3 EIS Composite Direct Collection Mapping by EIS Record Type

EIS Record Type | Mapping Behavior
--- | ---
Indexed | Maps directly to a subrecord in the indexed recordFoot 1 .
Mapped | Maps directly to a subrecord in the mapped recordFootref 1.
XML | Maps directly to an attribute or text node in the XML recordFoot 2 .

Footnote 1 See also "Composite EIS Mappings".

Footnote 2 See also "XML Composite Direct Collection Mapping".

Figure 56-5 illustrates a composite direct collection mapping between `Order` class attribute `items` and an XML record. The `Order` attribute `items` is a collection type (such as `Vector`). It is mapped to an XML record composed of an `order` element that contains a sequence of `item` elements.
