Annotation Type XmlElementWrapper

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

Generates a wrapper element around XML representation. This is primarily intended to be used to produce a wrapper XML element around collections. The annotation therefore supports two forms of serialization shown below.

    //Example: code fragment
      int[] names;

    // XML Serialization Form 1 (Unwrapped collection)
    <names> ... </names>
    <names> ... </names>
 
    // XML Serialization Form 2 ( Wrapped collection )
    <wrapperElement>
       <names> value-of-item </names>
       <names> value-of-item </names>
       ....
    </wrapperElement>
 

The two serialized XML forms allow a null collection to be represented either by absence or presence of an element with a nillable attribute.

Usage

The @XmlElementWrapper annotation can be used with the following program elements:

• JavaBean property
• non static, non transient field

The usage is subject to the following constraints:

• The property must be a collection property
• This annotation can be used with the following annotations: XmlElement, XmlElements, XmlElementRef, XmlElementRefs, XmlJavaTypeAdapter
.

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

Optional Element Summary

java.lang.String	name Name of the XML wrapper element.
java.lang.String	namespace XML target namespace of the XML wrapper element.
boolean	nillable If true, the absence of the collection is represented by using xsi:nil='true'.

name

public abstract java.lang.String name

Name of the XML wrapper element. By default, the XML wrapper element name is derived from the JavaBean property name.

Default:

"##default"

namespace

public abstract java.lang.String namespace

XML target namespace of the XML wrapper element. namespace() must be a valid namespace URI. The default XML namespace is the XML namespace of the enclosing class of the Javabean property.

Default:

"##default"

nillable

public abstract boolean nillable

If true, the absence of the collection is represented by using xsi:nil='true'. Otherwise, it is represented by the absence of the element.

Default:

false
