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

    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).

      • trySplit

        public IntSpliterator trySplit()
        Throws:
        java.lang.IndexOutOfBoundsException - if the return of computeSplitPoint() was < pos or > {@link #getMaxPos()}.
        Implementation Specification:
        This implementation always returns a prefix of the elements, in order to comply with the Spliterator.ORDERED property. This means this current iterator does not need to to update what getMaxPos() returns in response to this method (but it may do "book-keeping" on it based on binding strategy).

        The split point is computed by computeSplitPoint(); see that method for details.
