abstract class KVStoreView[T] extends Iterable[T]
A configurable view that allows iterating over values in a KVStore.
The different methods can be used to configure the behavior of the iterator. Calling the same method multiple times is allowed; the most recent value will be used.
The iterators returned by this view are of type KVStoreIterator; they auto-close
when used in a for loop that exhausts their contents, but when used manually, they need
to be closed explicitly unless all elements are read.

- def parent(value: AnyRef): KVStoreView[T]
Defines the value of the parent index when iterating over a child index.
Defines the value of the parent index when iterating over a child index. Only elements that match the parent index's value will be included in the iteration.
Required for iterating over child indices, will generate an error if iterating over a parent-less index.
- def reverse(): KVStoreView[T]
Reverses the order of iteration.
Reverses the order of iteration. By default, iterates in ascending order.
- def skip(n: Long): KVStoreView[T]
Skips a number of elements at the start of iteration.
Skips a number of elements at the start of iteration. Skipped elements are not accounted when using
