public abstract static class IntBigSpliterators.LateBindingSizeIndexBasedSpliterator
extends IntBigSpliterators.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).
