RxJava可观察与去年状态

Question

我开始与RxJava，我想创建一个可观察，可以节省最后状态...

在RxSwift，这将是变量（https://github.com/ReactiveX/RxSwift/blob/master/Documentation/GettingStarted.md#variables），但我不能发现RxJava的equivalente ...

我发现周围的工作，但它的很多的样板代码

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当量在该

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

你能帮我吗？由于

BehaviorSubject有值（）方法，它返回它的当前值

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