| * The annotation used to declare a Servlet {@link javax.servlet.Filter}. <br> |
| * <br> |
| * |
| * This annotation will be processed by the container during deployment, the |
| * Filter class in which it is found will be created as per the configuration |
| * and applied to the URL patterns, {@link javax.servlet.Servlet}s and |
| * {@link javax.servlet.DispatcherType}s.<br> |
| * <br> |
| * |
| * If the name attribute is not defined, the fully qualified name of the class |
| * is used.<br> |
| * <br> |
| * |
| * At least one URL pattern MUST be declared in either the {@code value} or |
| * {@code urlPattern} attribute of the annotation, but not both.<br> |
| * <br> |
| * |
| * The {@code value} attribute is recommended for use when the URL pattern is |
| * the only attribute being set, otherwise the {@code urlPattern} attribute |
| * should be used.<br> |
| * <br> |
| * |
| * The annotated class MUST implement {@link javax.servlet.Filter}. |
| * |
| * E.g. |
| * |
| * <code>@WebFilter("/path/*")</code><br> |
| * <code>public class AnExampleFilter implements Filter { ... </code><br> |
| * |
| * @since Servlet 3.0 (Section 8.1.2) |
