Inherited functions

From class Adapter

`Unit`	`bindViewHolder(@NonNull holder: VH, position: Int)` This method internally calls `onBindViewHolder(ViewHolder, int)` to update the `ViewHolder` contents with the item at the given position and also sets up some private fields to be used by RecyclerView. Adapters that merge other adapters should use `bindViewHolder(ViewHolder, int)` when calling nested adapters so that RecyclerView can track which adapter bound the `ViewHolder` to return the correct position from `ViewHolder#getBindingAdapterPosition()` method. They should also override the `findRelativeAdapterPositionIn(Adapter, ViewHolder, int)` method.
`VH`	`createViewHolder(@NonNull parent: ViewGroup, viewType: Int)` This method calls `onCreateViewHolder(ViewGroup, int)` to create a new `ViewHolder` and initializes some private fields to be used by RecyclerView.
`Int`	`findRelativeAdapterPositionIn(@NonNull adapter: RecyclerView.Adapter<out RecyclerView.ViewHolder!>, @NonNull viewHolder: RecyclerView.ViewHolder, localPosition: Int)` Returns the position of the given `ViewHolder` in the given `Adapter`. If the given `Adapter` is not part of this `Adapter`, `RecyclerView#NO_POSITION` is returned.
`Long`	`getItemId(position: Int)` Return the stable ID for the item at `position`. If `hasStableIds()` would return false this method should return `NO_ID`. The default implementation of this method returns `NO_ID`.
`Int`	`getItemViewType(position: Int)` Return the view type of the item at `position` for the purposes of view recycling. The default implementation of this method returns 0, making the assumption of a single view type for the adapter. Unlike ListView adapters, types need not be contiguous. Consider using id resources to uniquely identify item view types.
`RecyclerView.Adapter.StateRestorationPolicy`	`getStateRestorationPolicy()` Returns when this Adapter wants to restore the state.
`Boolean`	`hasObservers()` Returns true if one or more observers are attached to this adapter.
`Boolean`	`hasStableIds()` Returns true if this adapter publishes a unique `long` value that can act as a key for the item at a given position in the data set. If that item is relocated in the data set, the ID returned for that item should be the same.
`Unit`	`notifyDataSetChanged()` Notify any registered observers that the data set has changed. There are two dif
