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, javax.xml.bind.annotation.adapters.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>
