| <div class="block">Maps a JavaBean property to a XML element derived from property name. |
| |
| <p> <b>Usage</b> |
| <p> |
| <code>@XmlElement</code> annotation can be used with the following program |
| elements: |
| <ul> |
| <li> a JavaBean property </li> |
| <li> non static, non transient field </li> |
| <li> within <a href="XmlElements.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlElements</code></a> |
| </ul> |
| |
| The usage is subject to the following constraints: |
| <ul> |
| <li> This annotation can be used with 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="XmlElementWrapper.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlElementWrapper</code></a>, |
| <a href="adapters/XmlJavaTypeAdapter.html" title="annotation in jakarta.xml.bind.annotation.adapters"><code>XmlJavaTypeAdapter</code></a></li> |
| <li> 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 <a href="XmlElements.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlElements</code></a> then, |
| <code>@XmlElement.type()</code> must be DEFAULT.class since the |
| collection item type is already known. </li> |
| </ul> |
| |
| <p> |
| 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. |
| |
| <p> |
| <b>Example 1: </b> Map a public non static non final field to local |
| element |
| <pre> |
| //Example: Code fragment |
| public class USPrice { |
| @XmlElement(name="itemprice") |
| public java.math.BigDecimal price; |
| } |
| <code> |
| |
| <!-- Example: Local XML Schema element --> |
| <xs:complexType name="USPrice"/> |
| <xs:sequence> |
| <xs:element name="itemprice" type="xs:decimal" minOccurs="0"/> |
| </sequence> |
| </xs:complexType> |
| </code></pre> |
| <p> |
| |
| <b> Example 2: </b> Map a field to a nillable element. |
| <pre> |
| //Example: Code fragment |
| public class USPrice { |
| @XmlElement(nillable=true) |
| public java.math.BigDecimal price; |
| } |
| <code> |
| |
| <!-- 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> |
| </code></pre> |
| <p> |
| <b> Example 3: </b> Map a field to a nillable, required element. |
| <pre> |
| //Example: Code fragment |
| public class USPrice { |
| @XmlElement(nillable=true, required=true) |
| public java.math.BigDecimal price; |
| } |
| <code> |
| |
| <!-- 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> |
| </code></pre> |
| |
| <p> <b>Example 4: </b>Map a JavaBean property to an XML element |
| with anonymous type.</p> |
| <p> |
| See Example 6 in @<a href="XmlType.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlType</code></a>.</div> |
