Spark 연구 노트 5: 주요 공장 유형 Native Manager(오리지널)

Native Manager는 현재 주로 플래시 스크린 플러그인(org.jive software.spark.plugin.flashing) 서비스를 위한 것으로 주로 NativeHandler 목록을 조작하고 NativeHandler 인터페이스의 주요 실현 유형은 FlashingHandler, FlashingHandler의 정의이다.

public class FlashingHandler implements NativeHandler {
    private FlashWindow flasher;

    public FlashingHandler() {
        flasher = new FlashWindow();
    }

    @Override
    public void flashWindow(Window window) {
        FlashingPreference preference = (FlashingPreference) SparkManager.getPreferenceManager().getPreference(FlashingPreference.NAMESPACE);
        if (preference.getPreferences().isFlashingEnabled()) {
            if (preference.getPreferences().getFlashingType().equals(FlashingPreferences.TYPE_CONTINOUS)) {
                flasher.startFlashing(window);
            }
            else if (preference.getPreferences().getFlashingType().equals(FlashingPreferences.TYPE_TEMPORARY)) {
                flasher.flash(window, 1500, 5);
            }
        }
    }

 
실제로 전체 프로젝트의 Native Manager가 실례화된 적이 없다는 것은 정말 이상한 일이지만, 이런 종류는 특별히 중요한 것이 아니다.
