using array of object in firebase -

-

firebase recommended storing data in object .

but found hard fit want.

 - want size of object.  - first object  - , last object.

does firebase support on object?

it's not easy retrieve size of object without storing (and updating) separately @ moment.

you can retrieve first object in list using ref.startat().limit(1) , last object using ref.endat().limit(1).

i understand in c# class passed reference. mean when store said class in list stored reference well, or better said c# style "pointer" of sorts? mean list n elements of class not take memory n times size of class n times size of reference class? or thinking wrong? you're right. if create n elements of class t, , class t uses, say, 10 bytes, takes on order of 10*n memory. if store in list<t> , still have 10*n memory objects, plus n times size of c# reference , list overhead. if store same elements in 2 lists, have 10*n objects, plus 2*n references, , 2 times list overhead. they're pointing @ same underlying objects.
