/**
 * Annotation that specifies that a method in an event class should be used to
 * filter out events.
 * <p>
 * For the method to be valid it must return a {@code SettingControl} and only have one
 * parameter, which should be a non-abstract subclass of {@link SettingControl}
 * <p>
 * The return value of the method specifies whether the event is to be
 * written to the Flight Recorder system or not.
 * <p>
 * The following example shows how to annotate a method in an event class.
 *
 * <pre>
 * <code>
 * class HelloWorld extend Event {
 *
 *   {@literal @}Label("Message");
 *   String message;
 *
 *   {@literal @}SettingDefinition;
 *   {@literal @}Label("Message Filter");
 *   public boolean filter(RegExpControl regExp) {
 *     return regExp.matches(message);
 *   }
 * }
 * </code>
 * </pre>
 *
 * For an example of how the setting controls are defined, see
 * {@link SettingControl}.
 *
 * @see SettingControl
