javax.xml.bind.annotation

Annotation Type XmlAttribute


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

    Maps a JavaBean property to a XML attribute.

    Usage

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

    • JavaBean property
    • field

    A static final field is mapped to a XML fixed attribute.

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

    The usage is subject to the following constraints:
    • If type of the field or the property is a collection type, then the collection item type must be mapped to schema simple type.
           // Examples
           @XmlAttribute List<Integer> items; //legal
           @XmlAttribute List<Bar> foo; // illegal if Bar does not map to a schema simple type
       
    • If the type of the field or the property is a non collection type, then the type of the property or field must map to a simple schema type.
           // Examples
           @XmlAttribute int foo; // legal
           @XmlAttribute Foo foo; // illegal if Foo does not map to a schema simple type
       
    • This annotation can be used with the following annotations: XmlID, XmlIDREF, XmlList, XmlSchemaType, XmlValue, XmlAttachmentRef, XmlMimeType, XmlInlineBinaryData, XmlJavaTypeAdapter.

    Example 1: Map a JavaBean property to an XML attribute.

         //Example: Code fragment
         public class USPrice {
             @XmlAttribute
             public java.math.BigDecimal getPrice() {...} ;
             public void setPrice(java.math.BigDecimal ) {...};
         }
    
         <!-- Example: XML Schema fragment -->
         <xs:complexType name="USPrice">
           <xs:sequence>
           </xs:sequence>
           <xs:attribute name="price" type="xs:decimal"/>
         </xs:complexType>
     

    Example 2: Map a JavaBean property to an XML attribute with anonymous type.

    See Example 7 in @XmlType.

    Example 3: Map a JavaBean collection property to an XML attribute.

         // Example: Code fragment
         class Foo {
             ...
             @XmlAttribute List<Integer> items;
         }
    
         <!-- Example: XML Schema fragment -->
         <xs:complexType name="foo">
           ...
           <xs:attribute name="items">
             <xs:simpleType>
               <xs:list itemType="xs:int"/>
             </xs:simpleType>
         </xs:complexType>
