− | In most cases, EclipseLink can determine the target format in the XML document. However, there are cases where you must specify which one of a number of possible targets EclipseLink should use. For example, a <tt>java.util.Calendar</tt> could be marshalled to a schema <tt>date</tt>, <tt>time</tt>, or <tt>dateTime</tt> node, or a <tt>byte[]</tt> could be marshalled to a schema <tt>hexBinary</tt> or <tt>base64Binary</tt> node.

When EclipseLink unmarshalls the XML document, it tries each of the union types until it can make a successful conversion. The first schema type in the union is <tt>xsd:decimal</tt>. Because "10.5" is a valid decimal, EclipseLink converts the value to the appropriate type. If the <tt>Object</tt> attribute is specific enough to trigger an appropriate value, EclipseLink will use that type instead. Otherwise, EclipseLink uses a default (in this case <tt>BigDecimal</tt>). You can override this behavior in Java code.

| + | |
− | If the type of a node is not defined in your XML schema, you can configure an XML direct mapping to use the <tt>xsi:type</tt> attribute to provide type information.
| + | |
− | | + | |
− | Given the XML schema fragment in the [[#Example 58-22|Schema for XML Direct Mapping with Simple Type Translator]] example, the [[#Figure 58-13|Java Class for XML Direct Mapping with Simple Type Translator]] figure illustrates a Java class that can be mapped to a corresponding XML document.
