FRP - Functional Reactive Programming
- 2. いいか?みんな (?д? ) (| y |) v方侏プログラミングの勣殆をリアクティブプログラミングに栽わせると v方侏 (?д?) リアクティブ 棕| y |棕 FRPになるのだ ( ?д?) FRP (棕棕

- 5. Java Objective-C FRP RxJava compile 'com.netflix.rxjava:rxjava-core:+' ReactiveCocoa pod 'ReactiveCocoa'
- 7. ( ) Pull java.lang.Iterable, RACSequence(ReactiveCocoa) Push rx.Observable(RxJava), RACSignal(ReactiveCocoa) Push
- 10. (Java) ViewObservable.input(mEditText, false) .subscribe(new Action1<String>() { @Override public void call(String s) { Log.d("LOG", "New value: " + s); } }, new Action1<Throwable>() { @Override public void call(Throwable t) { Log.d("LOG", "Error: " + t.getMessage()); } }, new Action0() { Override public void call() { Log.d("LOG", "Completed."); } });
