+/**
+ * This class is intended to handle <field> element.
+ * This element simplifies access to the fields.
+ * If the {@code class} attribute is specified
+ * this element accesses static field of specified class.
+ * This element defines getter if it contains no argument.
+ * It returns the value of the field in this case.
+ * For example:<pre>
+ * &lt;field name="TYPE" class="java.lang.Long"/&gt;</pre>
+ * is equivalent to {@code Long.TYPE} in Java code.
+ * This element defines setter if it contains one argument.
+ * It does not return the value of the field in this case.
+ * For example:<pre>
+ * &lt;field name="id"&gt;&lt;int&gt;0&lt;/int&gt;&lt;/field&gt;</pre>
+ * is equivalent to {@code id = 0} in Java code.
+ * <p>The following attributes are supported:
+ * <dl>
+ * <dt>name
+ * <dd>the field name
+ * <dt>class
+ * <dd>the type is used for static fields only
+ * <dt>id
+ * <dd>the identifier of the variable that is intended to store the result
+ * </dl>
