Phase 6 - Substitution Groups (page under construction)
Provide support for substitution groups.
Annotations
The following annotations will be targeted in this phase:
Annotation | XML Metadata Tag | Package | Type | Field | Method |
---|---|---|---|---|---|
XmlElements | xml-elements | X | X | ||
XmlElementRef | xml-element-ref | X | X | ||
XmlElementRefs | xml-element-refs | X |
X |
Example: XmlElements annotation
Java Metadata
The following example will demonstrate how the XmlElements annotation can be applied:
org.example.Foo.java
package org.example; @javax.xml.bind.annotation.XmlRootElement public class Foo { @javax.xml.bind.annotation.XmlElementWrapper(name="items") @javax.xml.bind.annotation.XmlElements({ @javax.xml.bind.annotation.XmlElement(name="A", type=Integer.class), @javax.xml.bind.annotation.XmlElement(name="B", type=Float.class) }) public java.util.List items; }
XML Metadata
xml-elements
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.Foo
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.Foo"> <xml-root-element name="foo"/> <java-attributes> <xml-elements java-attribute="items"> <xml-element java-attribute="A" type="java.lang.Integer" /> <xml-element java-attribute="B" type="java.lang.Float" /> </xml-elements> </java-attributes> </java-type> </java-types> </xml-bindings>
Example: XmlElementRef annotation
Java Metadata
The following example will demonstrate how the XmlElementRef annotation can be applied:
org.example.Foos.java
package org.example; @javax.xml.bind.annotation.XmlRootElement public class Foos { @javax.xml.bind.annotation.XmlElementWrapper(name="items") @javax.xml.bind.annotation.XmlElementRef(type=Bar.class) public java.util.List<Bar> items; }
org.example.Bar.java
package org.example; @javax.xml.bind.annotation.XmlRootElement(name="foobar") public class Bar { public int id; }
XML Metadata
xml-element-ref
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.Foos
and org.example.Bar
classes.
<?xml version="1.0" encoding="US-ASCII"?> <xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"> <java-types> <java-type name="org.eclipse.persistence.testing.jaxb.externalizedmetadata.xmlelementref.Foos"> <xml-root-element name="foos" /> <java-attributes> <xml-element-ref java-attribute="items" type="org.eclipse.persistence.testing.jaxb.externalizedmetadata.xmlelementref.Bar" > <xml-element-wrapper name="items" /> </xml-element-ref> </java-attributes> </java-type> <java-type name="org.eclipse.persistence.testing.jaxb.externalizedmetadata.xmlelementref.Bar"> <xml-root-element name="foobar" /> </java-type> </java-types> </xml-bindings>
