user3762200 :
I'm using RxJava and I want to combine 12 different observables using the operator combineLatest.
I saw a function prototype that takes a list of observables and an implementation of FuncN but I'm not sure how to do this, I'm having trouble implementing the call method.
Can someone show me an example?
Egor Neliuba :
There is a combineLatest that takes a List of observables. Here's an example on how to use it:
List<Observable<?>> list = Arrays.asList(Observable.just(1), Observable.just("2"));
Observable.combineLatest(list, new FuncN<String>() {
@Override
public String call(Object... args) {
String concat = "";
for (Object value : args) {
if (value instanceof Integer) {
concat += (Integer) value;
} else if (value instanceof String) {
concat += (String) value;
}
}
return concat;
}
});
