Annotation Type XmlElement



  • @Retention(RUNTIME)
    @Target({FIELD,METHOD,PARAMETER})
    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:

    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" minOccurs="0"/>
           </sequence>
         </xs:complexType>
       

    Example 2: 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" minOccurs="0"/>
           </sequence>
         </xs:complexType>
       

    Example 3: Map a field to a nillable, required element.

         //Example: Code fragment
         public class USPrice {
            @XmlElement(nillable=true, required=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" minOccurs="1"/>
           </sequence>
         </xs:complexType>
       

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

    • Optional Element Summary

      Optional Elements 
      Modifier and Type Optional Element Description
      String defaultValue
      Default value of this element.
      String name
      Name of the XML Schema element.
      String namespace
      XML target namespace of the XML Schema element.
      boolean nillable
      Customize the element declaration to be nillable.
      boolean required
      Customize the element declaration to be required.
      Class type
      The Java class being referenced.
    • Element Detail

      • name

        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

        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.

        Default:
        false
      • required

        boolean required
        Customize the element declaration to be required.

        If required() is true, then Javabean property is mapped to an XML schema element declaration with minOccurs="1". maxOccurs is "1" for a single valued property and "unbounded" for a multivalued property.

        If required() is false, then the Javabean property is mapped to XML Schema element declaration with minOccurs="0". maxOccurs is "1" for a single valued property and "unbounded" for a multivalued property.

        Default:
        false
      • namespace

        String namespace
        XML target namespace of the XML Schema element.

        If the value is "##default", then the namespace is determined as follows:

        1. If the enclosing package has XmlSchema annotation, and its elementFormDefault is QUALIFIED, then the namespace of the enclosing class.
        2. Otherwise '' (which produces unqualified element in the default namespace.
        Default:
        "##default"
      • defaultValue

        String defaultValue
        Default value of this element.
