//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.
The @XmlElementWrapper annotation can be used with the following program elements:
The usage is subject to the following constraints:
See "Package Specification" in javax.xml.bind.package javadoc for additional common information.
|Modifier and Type||Optional Element and Description|
Name of the XML wrapper element.
XML target namespace of the XML wrapper element.
If true, the absence of the collection is represented by using xsi:nil='true'.
Customize the wrapper element declaration to be required.
public abstract String name
public abstract String namespace
If the value is "##default", then the namespace is determined as follows:
public abstract boolean nillable
public abstract boolean required
If required() is true, then the corresponding generated XML schema element declaration will have minOccurs="1", to indicate that the wrapper element is always expected.
Note that this only affects the schema generation, and not the unmarshalling or marshalling capability. This is simply a mechanism to let users express their application constraints better.
