Phase 10 - XmlRegistry (page under construction)

Provide support for ObjectFactory methods.

Annotations

The following annotations will be targetted in this phase:

Annotation XML Metadata Tag Package Type Field Method
XmlElementDecl xml-element-decl     X X
XmlRegistry xml-registry   X    

Example: XmlRegistry and XmlElementDecl Annotations

Java Metadata

The following example will demonstrate how the XmlRegistry and XmlElementDecl annotations can be applied:

org.example.ObjectFactory.java

package org.example;
 
@javax.xml.bind.annotation.XmlRegistry
class ObjectFactory {
    @javax.xml.bind.annotation.XmlElementDecl(name="foo")
    javax.xml.bind.JAXBElement<String> createFoo(String s) { return "fooAsString"; }
}

XML Metadata

xml-registry

If this is present in XML, the corresponding annotation will be ignored, and the true/false value set in XML used instead.

xml-element-decl

If this is present in XML, the corresponding annotation will be completely replaced.

org/example/eclipselink-oxm.xml

This XML file represents metadata overrides for the "org.example" package. 

<?xml version="1.0" encoding="US-ASCII"?>
<xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm">
    <xml-registries>
        <xml-registry name="org.example.ObjectFactory">
            <xml-element-decl name="foo" />
        </xml-registry>
    </xml-registries>
</xml-bindings>
