Phase 4 (page under construction)
Provide support for high level metadata.
Annotations
The following annotations will be targetted in this phase:
| Annotation | Package | Type | Field | Method |
|---|---|---|---|---|
| XmlElementWrapper |
X | X | ||
| XmlList |
X | X | ||
| XmlValue |
X | X | ||
| XmlMixed |

Example: XmlElementWrapper
Java Metadata
The following example will demonstrate how an XmlElementWrapper annotation can be applied:
org.example.Employee.java
package org.example; import javax.xml.bind.annotation.XmlElementWrapper; public class Employee { @XmlElementWrapper(name="my-digits", nillable=true, required=true) public int[] digits; }
XML Metadata
xml-element-wrapper
If this is present in the XML then it completely replaces the corresponding annotation.
org/example/eclipselink-oxm.xml
This XML file represents metadata overrides for the "org.example.Employee" class.
<?xml version="1.0" encoding="US-ASCII"?> <xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"> <java-types> <java-type name="org.example.Employee"> <java-attributes> <xml-element-wrapper java-attribute="digits" name="my-digits" nillable="true" required="true"/> </java-attributes> </java-type> </java-types> </xml-bindings>
