| <div class="block"><p> |
| Maps a JavaBean property to a XML attribute. |
| |
| <p> <b>Usage</b> </p> |
| <p> |
| The <code>@XmlAttribute</code> annotation can be used with the |
| following program elements: |
| <ul> |
| <li> JavaBean property </li> |
| <li> field </li> |
| </ul> |
| |
| <p> A static final field is mapped to a XML fixed attribute. |
| |
| <p>See "Package Specification" in jakarta.xml.bind.package javadoc for |
| additional common information.</p> |
| |
| The usage is subject to the following constraints: |
| <ul> |
| <li> If type of the field or the property is a collection |
| type, then the collection item type must be mapped to schema |
| simple type. |
| <pre> |
| // Examples |
| @XmlAttribute List<Integer> items; //legal |
| @XmlAttribute List<Bar> foo; // illegal if Bar does not map to a schema simple type |
| </pre> |
| </li> |
| <li> 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. |
| <pre> |
| // Examples |
| @XmlAttribute int foo; // legal |
| @XmlAttribute Foo foo; // illegal if Foo does not map to a schema simple type |
| </pre> |
| </li> |
| <li> This annotation can be used with the following annotations: |
| <a href="XmlID.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlID</code></a>, |
| <a href="XmlIDREF.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlIDREF</code></a>, |
| <a href="XmlList.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlList</code></a>, |
| <a href="XmlSchemaType.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlSchemaType</code></a>, |
| <a href="XmlValue.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlValue</code></a>, |
| <a href="XmlAttachmentRef.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlAttachmentRef</code></a>, |
| <a href="XmlMimeType.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlMimeType</code></a>, |
| <a href="XmlInlineBinaryData.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlInlineBinaryData</code></a>, |
| <a href="adapters/XmlJavaTypeAdapter.html" title="annotation in jakarta.xml.bind.annotation.adapters"><code>XmlJavaTypeAdapter</code></a>.</li> |
| </ul> |
| |
| <p> <b>Example 1: </b>Map a JavaBean property to an XML attribute.</p> |
| <pre> |
| //Example: Code fragment |
| public class USPrice { |
| @XmlAttribute |
| public java.math.BigDecimal getPrice() {...} ; |
| public void setPrice(java.math.BigDecimal ) {...}; |
| } |
| <code> |
| |
| <!-- Example: XML Schema fragment --> |
| <xs:complexType name="USPrice"> |
| <xs:sequence> |
| </xs:sequence> |
| <xs:attribute name="price" type="xs:decimal"/> |
| </xs:complexType> |
| </code></pre> |
| |
| <p> <b>Example 2: </b>Map a JavaBean property to an XML attribute with anonymous type.</p> |
| See Example 7 in @<a href="XmlType.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlType</code></a>. |
| |
| <p> <b>Example 3: </b>Map a JavaBean collection property to an XML attribute.</p> |
| <pre> |
| // Example: Code fragment |
| class Foo { |
| ... |
| @XmlAttribute List<Integer> items; |
| } |
| <code> |
