@Retention(value=RUNTIME)
 @Target(value={FIELD,METHOD})
public @interface XmlElements

A container for multiple @XmlElement annotations. Multiple annotations of the same type are not allowed on a program element. This annotation therefore serves as a container annotation for multiple @XmlElements as follows:

 @XmlElements({ @XmlElement(...),@XmlElement(...) })
 

The @XmlElements annnotation can be used with the following program elements:

• a JavaBean property
• non static, non transient field

This annotation is intended for annotation a JavaBean collection property (e.g. List).

Usage

The usage is subject to the following constraints:

• This annotation can be used with the following annotations: @XmlIDREF, @XmlElementWrapper.
• If @XmlIDREF is also specified on the JavaBean property, then each @XmlElement.type() must contain a JavaBean property annotated with @XmlID.

See "Package Specification" in javax.xml.bind.package javadoc for additional common information.

Example 1: Map to a list of elements

 
 // Mapped code fragment
 public class Foo {
 @XmlElements(
 @XmlElement(name="A", type=Integer.class),
 @XmlElement(name="B", type=Float.class)
 }
 public List items;
 }
 <!-- XML Representation for a List of {1,2.5} 
 XML output is not wrapped using another element -->
 ...
 <A> 1 </A>
 <B> 2.5 </B>
 ...
 <!-- XML Schema fragment -->
 <xs:complexType name="Foo">
 <xs:sequence>
 <xs:choice minOccurs="0" maxOccurs="unbounded">
 <xs:element name="A" type="xs:int"/>
 <xs:element name="B" type="xs:float"/>
 <xs:choice>
 </xs:sequence>
 </xs:complexType>
 

Example 2: Map to a list of elements wrapped with another element

 
 // Mapped code fragment
 public class Foo {
 @XmlElementWrapper(name="bar")
 @XmlElements(
 @XmlElement(name="A", type=Integer.class),
 @XmlElement(name="B", type=Float.class)
 }
 public List items;
 }
 <!-- XML Schema fragment -->
 <xs:complexType name="Foo">
 <xs:sequence>
 <xs:element name="bar">
 <xs:complexType>
 <xs:choice minOccurs="0" maxOccurs="unbounded">
 <xs:element name="A" type="xs:int"/>
 <xs:element name="B" type="xs:float"/>
 </xs:choice>
 </xs:complexType>
 </xs:element>
 </xs:sequence>
 </xs:complexType>
 

Example 3: Change element name based on type using an adapter.

 class Foo {
 @XmlJavaTypeAdapter(QtoPAdapter.class)
 @XmlElements({
 @XmlElement(name="A",type=PX.class),
 @XmlElement(name="B",type=PY.class)
 })
 Q bar;
 }
 
 @XmlType abstract class P {...}
 @XmlType(name="PX") class PX extends P {...}
 @XmlType(name="PY") class PY extends P {...}
 <!-- XML Schema fragment -->
 <xs:complexType name="Foo">
 <xs:sequence>
 <xs:element name="bar">
 <xs:complexType>
 <xs:choice minOccurs="0" maxOccurs="unbounded">
 <xs:element name="A" type="PX"/>
 <xs:element name="B" type="PY"/>
 </xs:choice>
 </xs:complexType>
 </xs:element>
 </xs:sequence>
 </xs:complexType>
