27/**
28 * This class is intended to handle <long> element.
29 * This element specifies {@code long} values.
30 * The class {@link Long} is used as wrapper for these values.
31 * The result value is created from text of the body of this element.
32 * The body parsing is described in the class {@link StringElementHandler}.
33 * For example:<pre>
34 * &lt;long&gt;0xFFFF&lt;/long&gt;</pre>
35 * is shortcut to<pre>
36 * &lt;method name="decode" class="java.lang.Long"&gt;
37 *     &lt;string&gt;0xFFFF&lt;/string&gt;
38 * &lt;/method&gt;</pre>
39 * which is equivalent to {@code Long.decode("0xFFFF")} in Java code.
40 * <p>The following attribute is supported:
41 * <dl>
42 * <dt>id
43 * <dd>the identifier of the variable that is intended to store the result
44 * </dl>
