Annotation Type RequestParameterMap

@Target(value={TYPE,METHOD,PARAMETER,FIELD})
 @Qualifier
 @Retention(value=RUNTIME)
public @interface RequestParameterMap

The presence of this annotation (along with @Inject) on a field of type Map<String, String> causes the map returned from ExternalContext.getRequestParameterMap() to be injected as the value of that field.
