Comparing CBLQuery objects

[Jordan Wood]

I would like to take two CBLQuery objects and find out if they represent the same query on a view. I can compare the parameters that are important to me (startKey, endKey, groupLevel, mapOnly), but I can't check that the two queries actually reference the same view, since I see no way to find out what view created a query from the query object.

Is there a better way for me to compare two queries that have been created with separate calls to [myView createQuery]? Can I get the name of the view that created a CBLQuery? I am using this to update a set of CBLLiveQuery objects that my app keeps.

No, there isn’t an accessor for that. It seems like a reasonable thing to add, so you can file an issue on Github to request it.
As a workaround, you can make a data structure that maps query objects to views, for instance a custom class that has a query property and a view property, or an NSMapTable whose keys are query objects.
