Annotation Type XmlElement

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

Maps a JavaBean property to a XML element derived from property name.

Usage

@XmlElement annotation can be used with the following program elements:

• a JavaBean property
• non static, non transient field
• within XmlElements

The usage is subject to the following constraints:

• This annotation can be used with following annotations: XmlID, XmlIDREF, XmlList, XmlSchemaType, XmlValue, XmlAttachmentRef, XmlMimeType, XmlInlineBinaryData, XmlJavaTypeAdapter
• if the type of JavaBean property is a collection type of array, an indexed property, or a parameterized list, and this annotation is used with XmlElements then, @XmlElement.type() must be DEFAULT.class since the collection item type is already known.

A JavaBean property, when annotated with @XmlElement annotation is mapped to a local element in the XML Schema complex type to which the containing class is mapped.

Example 1: Map a public non static non final field to local element

     //Example: Code fragment
     public class USPrice {
         @XmlElement(name="itemprice")
         public java.math.BigDecimal price;
     }

     <!-- Example: Local XML Schema element -->
     <xs:complexType name="USPrice"/>
       <xs:sequence>
         <xs:element name="itemprice" type="xs:decimal"/>
       </sequence>
     </xs:complexType>
   

Example 2: Associate a global element with XML Schema type to which the class is mapped.

Note to Reviewers: Moved to XmlRootElement

Example 3: Map a field to a nillable element.

 
     //Example: Code fragment
     public class USPrice {
         @XmlElement(nillable=true)
         public java.math.BigDecimal price;
     }

     <!-- Example: Local XML Schema element -->
     <xs:complexType name="USPrice">
       <xs:sequence>
         <xs:element name="price" type="xs:decimal" nillable="true"/>
       </sequence>
     </xs:complexType>
   

Example 4: Map a JavaBean property to an XML element with anonymous type.

Optional Element Summary

java.lang.String	defaultValue Default value of this element.
java.lang.String	name Name of the XML Schema element.
java.lang.String	namespace Specifies the XML target namespace of the XML Schema element.
boolean	nillable Customize the element declaration to be nillable.
java.lang.Class	type The Java class being referenced.

name

public abstract java.lang.String name

Name of the XML Schema element.

If the value is "##default", then element name is derived from the JavaBean property name.

Default:

"##default"

nillable

public abstract boolean nillable

Customize the element declaration to be nillable.

If nillable() is true, then the JavaBean property is mapped to a XML Schema nillable element declaration.

If nillable() is false and the JavaBean property type is a collection type, then the JavaBean property is mapped to repeating occurance.

Otherwise, the JavaBean property is mapped to an an XML Schema element declaration with occurance range of 0..1.

Default:

false

namespace

public abstract java.lang.String namespace

Specifies the XML target namespace of the XML Schema element.

If the value is "##default", then the namespace is the namespace of the containing class. Otherwise, it must be a valid namespace URI.

Default:

"##default"

defaultValue

public abstract java.lang.String defaultValue

Default value of this element.
