我有一个同步可观测值和10个其他异步可观测值,它们取决于同步可观测值。如何将它们压缩在一起并得到最终结果?邮编仅接受9个参数..如果我必须将其拆分为2个邮编,那么由于我只有1个同步可观察到的东西,因此该怎么做。请帮忙。 下面是代码:这里的帐户是同步的。
Observable aObservable = getAObservable(accountId);
Account account = aObservable.toBlocking().single();
Observable<List<C>> cObservable = getCObservable(saleInfo);
Observable<B> bObservable = getBObservable(account);
Observable<D> dObservable = getDObservable(account);
Observable<E> eObservable = getEObservable(account);
Observable<F> fObservable = getFObservable(account);
Observable<G> gObservable = getGObservable(account);
Observable<H> hObservable = getHObservable(account);
Observable<I> iObservable = getIObservable(account);
Observable<J> jObservable = getJObservable(account);
Observable<SaleFile> observable =
Observable.zip(
cObservable,
bObservable,
dObservable,
eObservable,
fObservable,
gObservable,
hObservable,
iObservable,
jObservable,
(o1, o2, o3, o4, o5, o6, o7, o8, o9) ->
new SaleFile()
.withA(account)
.withB(o1)
.withC(o2)
.withD(o3)
.withE(o4)
.withF(o5)
.withG(o6)
.withH(o7)
.withI(o8)
.withJ(o9));
return observable.toBlocking().single();
答案 0 :(得分:0)
正如我在评论中提到的那样:您可以将压缩分为2个可观察对象,然后再次将其压缩。因此,它看起来像:
Observable<TmpObjectForFirstSeven> zip1 = Observable.zip(
observable1,
observable2,
observable3,
observable4,
observable5,
observable6,
observable7,
{(o1, o2, o3, o4, o5, o6, o7) ->
new TmpObjectForFirstSeven(o1, o2, o3, o4, o5, o6, o7)
}
)
Observable<TmpObjectForFirstThree> zip2 = Observable.zip(
observable8,
observable9,
observable10,
{(o8, o9, o10) ->
new TmpObjectForSecondThree(o8, o9, o10)
}
)
Observable<SaleFile> observable = Observable.zip(
zip1,
zip2,
{(tmpForSeven, tmpForThree) ->
new SaleFile().withA(account)
.withB(tmpForSeven.o1())
.withC(tmpForSeven.o2())
.withD(tmpForSeven.o3())
.withE(tmpForSeven.o4())
.withF(tmpForSeven.o5())
.withG(tmpForSeven.o6())
.withH(tmpForSeven.o7())
.withI(tmpForThree.o8())
.withJ(tmpForThree.o9()))
}
)
TmpObjectForFirstThree
和TmpObjectForFirstSeven
是一些只有3和7个字段的数据类。
