Annotation Type SettingDefinition

@Retention(RUNTIME)
@Target(METHOD)
public @interface SettingDefinition

Annotation that signifies that a method in an event class should be used to filter out events.

For the method to be valid it must return a boolean and only have one parameter, which should be a non-abstract subclass of SettingControl

The return value of the method should signify if the event should be committed or not.

Example.

 
 class HelloWorld extend Event {

   @Label("Message");
   String message;

   @SettingDefinition;
   @Label("Message Filter");
   public boolean filter(RegExpControl regExp) {
     return regExp.matches(message);
   }
 }
 
 

For an example of how setting controls can be defined see SettingControl.
