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 - Factory method
Java Metadata
The following example will demonstrate how the XmlRegistry and XmlElementDecl annotations can be applied:
org.example.ObjectFactory.java
package org.example; import javax.xml.bind.JAXBElement; import javax.xml.bind.annotation.XmlElementDecl; import javax.xml.bind.annotation.XmlRegistry; import javax.xml.namespace.QName; @XmlRegistry class ObjectFactory { @XmlElementDecl(name="foo") JAXBElement<String> createFoo(String s) { return new JAXBElement<String>(new QName("foo"), String.class, "Foo"); } }
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>
Example: XmlRegistry and XmlElementDecl Annotations - Element declaration with non local scope
Java Metadata
The following example will demonstrate how the XmlRegistry and XmlElementDecl annotations can be applied in the case where one or more xml-element-decl
declarations define a non-local scope:
org.example.ObjectFactory.java
package org.example; import javax.xml.bind.JAXBElement; import javax.xml.bind.annotation.XmlElementDecl; import javax.xml.bind.annotation.XmlRegistry; import javax.xml.namespace.QName; @XmlRegistry public class ObjectFactory { @XmlElementDecl(scope=FooBar.class,name="foo") JAXBElement<String> createFooBarFoo(String s) { return new JAXBElement<String>(new QName("foo"), String.class, FooBar.class, "FooBarFoo"); } @XmlElementDecl(scope=FooBar.class,name="bar") JAXBElement createFooBarBar(String s) { return new JAXBElement<String>(new QName("bar"), String.class, FooBar.class, "FooBarBar"); } @XmlElementDecl(name="foo") JAXBElement createFoo(Integer i) { return new JAXBElement<Integer>(new QName("foo"), Integer.class, Integer.parseInt("66")); }
org.example.FooBar.java
package org.example; import javax.xml.bind.annotation.XmlElementRef; import javax.xml.bind.annotation.XmlElementRefs; import javax.xml.bind.JAXBElement; class FooBar { @XmlElementRefs({ @XmlElementRef(name="foo",type=JAXBElement.class), @XmlElementRef(name="bar",type=JAXBElement.class) }) List<JAXBElement<String>> fooOrBar; }
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.
