public abstract static class LongSpliterators.LateBindingSizeIndexBasedSpliterator
extends LongSpliterators.AbstractIndexBasedSpliterator
A skeletal implementation for a spliterator backed by an index based data store. High performance concrete implementations (like the main Spliterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.

This class implements a late binding strategy. On a new, non-split instance, the max pos will track the given data store (usually it's size, hence the class' name). On the first split, the last index will be read from the backing data store one last time and then be fixed for the remaining duration of this instance.
The returned split should should also be have a constant maxPos.

As the abstract methods in this class are used in inner loops, it is generally a good idea to override the class as final as to encourage the JVM to inline them (or alternatively, override the abstract methods as final).
