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