RxJava可觀察與去年狀態

Question

我開始與RxJava，我想創建一個可觀察，可以節省最後狀態...

在RxSwift，這將是變量（https://github.com/ReactiveX/RxSwift/blob/master/Documentation/GettingStarted.md#variables），但我不能發現RxJava的equivalente ...

我發現周圍的工作，但它的很多的樣板代碼

private boolean isGettingCompanies = false; 

public boolean isGettingCompanies() { 
    return isGettingCompanies; 
} 

private void setIsGettingCompanies(boolean isGettingCompanies) { 
    this.isGettingCompanies = isGettingCompanies; 
    isGettingCompaniesPublishSubject.onNext(isGettingCompanies); 
} 

private final PublishSubject<Boolean> isGettingCompaniesPublishSubject = PublishSubject.create(); 

public Observable<Boolean> isGettingCompaniesPublishSubject() { 
    return isGettingCompaniesPublishSubject.asObservable(); 
} 

的RxSwift當量在該

private(set) var isGettingCompanies: Variable = Variable(false) 

你能幫我嗎？由於

BehaviorSubject有值（）方法，它返回它的當前值

final BehaviorSubject<Boolean> subject = BehaviorSubject.<Boolean>create(false); 
final Boolean value = subject.getValue();
