如何使用第四个源扩展 Observables.combineLatest() ？

发布于 01-09 04:01 字数 1922 浏览 5 评论 0原文

想象一下，有两个带有字符串的 BehaviourSubject：

private val subjectLocationA = BehaviorSubject.createDefault("London")
private val subjectLocationB = BehaviorSubject.createDefault("Paris")

我是否更新了每个位置

subjectLocationA.onNext("Denver")

一个枚举类

@Serializable
enum class ActiveLocationList(@StringRes val value: Int) {
    ALL_LOCATION("all"),
    MY_FAVLOCATION("favorites")
}

，然后我在 Observable 中使用了

val settingsActiveLocationList: Observable<ActiveLocationList>

：我将上面的 Subjects 和 Observables< /code> via combineLatest()：

Observables.combineLatest(
            subjectLocationA,
            subjectLocationB,
            settingsActiveLocationList,
        ).switchMap { (locationA, locationB, activeLocationList) ->
            //..
            }

现在我想根据上面的示例扩展第三个位置主题 subjectLocationC。但我即将扩展 mergeLatest:

Observables.combineLatest(
            subjectLocationA,
            subjectLocationB,
            subjectLocationC,
            settingsActiveLocationList,
        ).switchMap { (locationA, locationB, locationC, activeLocationList) ->
        //..

IDE 抱怨

类型不匹配。

必需：（类型变量（T1），类型变量（T2），类型变量（T3））→类型变量（R）

发现：可观察

并且

无法推断此参数的类型。请明确指定。

根据 Observables 实现，除其他外

fun <T1 : Any, T2 : Any, T3 : Any> combineLatest

，

inline fun <T1 : Any, T2 : Any, T3 : Any, T4 : Any, R : Any> combineLatest

但没有介于两者之间？！我想我需要

fun <T1 : Any, T2 : Any, T3 : Any, T4 : Any> combineLatest

还是我错了？也许有解决方法吗？我缺少什么？

原文

Imagine there are two BehaviourSubject with Strings:

private val subjectLocationA = BehaviorSubject.createDefault("London")
private val subjectLocationB = BehaviorSubject.createDefault("Paris")

were I update location each like

subjectLocationA.onNext("Denver")

Then I have a enum class

@Serializable
enum class ActiveLocationList(@StringRes val value: Int) {
    ALL_LOCATION("all"),
    MY_FAVLOCATION("favorites")
}

used in a Observable:

val settingsActiveLocationList: Observable<ActiveLocationList>

I combine the above Subjects and Observables via combineLatest():

Observables.combineLatest(
            subjectLocationA,
            subjectLocationB,
            settingsActiveLocationList,
        ).switchMap { (locationA, locationB, activeLocationList) ->
            //..
            }

Now I would like to extend a third location subject subjectLocationC according to above example. But I am about to extend the combineLatest:

Observables.combineLatest(
            subjectLocationA,
            subjectLocationB,
            subjectLocationC,
            settingsActiveLocationList,
        ).switchMap { (locationA, locationB, locationC, activeLocationList) ->
        //..

IDE complains with

Type mismatch.

Required: (TypeVariable(T1), TypeVariable(T2), TypeVariable(T3)) → TypeVariable(R)

Found: Observable

and

Cannot infer a type for this parameter. Please specify it explicitly.

According to the Observables implementation says amongst others

fun <T1 : Any, T2 : Any, T3 : Any> combineLatest

and

inline fun <T1 : Any, T2 : Any, T3 : Any, T4 : Any, R : Any> combineLatest

but nothing in between?! I think I would need

fun <T1 : Any, T2 : Any, T3 : Any, T4 : Any> combineLatest

or am I wrong? Is there a workaround maybe? What am I missing?
