@samtstern There are some Auth lint errors exists that's why Trivis CI failed.

@PatilShreyas thanks for this! Just a few comments.

+     *
+     * @param newQuery is a new updated query.
+     */
+    public abstract void updateQuery(@NonNull Query newQuery);


Should this be added in BaseObservableSnapshotArray instead? It seems a bit strange that this would be the only method defined on ObservableSnapshotArray

Because BaseObservableSnapshotArray is inherited in both ObservableSnapshotArray of Firestore as well as Firebase realtime database too. And most importantly, the Query class of both databases are not the same.

Firestore Query Class: com.google.firebase.firestore.Query

Firebase Query Class: com.google.firebase.database.Query

If we add this method in BaseObservableSnapshotArray then Query parameter will be different for them. What else can we do here?

I would say let's just not make this part of the base class at all, it can just be something implemented in each of the Array classes.

That will also allow us to give the indexed version a better name: updateKeyQuery()

We have instantiated FirestoreArray by its superclass references in Adapter classes. So, Will it be fine them to be instantiated as Array classes?

Fine 😃. Okay then 👍 .

I have some questions.

If I instantiate mSnapshots as FirebaseArray' as then how to take care of FirebaseIndexArray`?

How could we know that when to call updateQuery() or updateKeyQuery()?
In FirebaseRecyclerAdapter if I create an instance of FirebaseArray then we can't instantiate FirebaseIndexArray. How to do it?

Oh no that is a problem ... any ideas? I don't know why I am so opposed to adding updateQuery to the ObservabeSnapshotArray classes ... it just feels wrong. But maybe that is the best way.

I also thought a lot about it before implementation in ObservableSnapshotArray class. But I can't find anything helpful.

I had one idea. But that idea was not much good to implement. Means, it's not good practice to implement. I had idea to use instanceof to check whether it's instance of Firebase array or index array. We will check it in our method and by casting we will call array class method. That was the idea.

Why is this lint suppression added in this PR when nothing else about this file changed?

Because it caused an error when I run the command gradlew assembleDebug proguard-tests:build check

When I checked that class, it's showing me the red line under return statement showing a suggestion to add this line.

Ok I am fine with this, although I bet if we revert the unrelated changes in this PR, this will go away.

Can you explain why we need all of these kotlin changes in this PR? Are they related?

No. I just updated it as it's on my system.

Ok let's revert these changes since they are not related to the feature.

@PatilShreyas ok I did some thinking and experimenting. First I found better words to explain myself :-) the reason I am not comfortable with updateQuery on ObservableSnapshotArray is because that class previous did not know that Query existed at all.

Second I think it may be better to structure this as setOptions where instead of just replacing the query you replace the whole options object you used to start the Adapter. Here's an example of how that might look (for RTDB only):

What do you think?

PatilShreyas · 2019-07-26T00:22:56Z

Right @samtstern!

@samtstern I have merged your PR and make changes as you suggested. Also implemented in Firestore adapter. Also, tested updateOptions on adapter.
