public abstract static class ByteSpliterators.AbstractIndexBasedSpliterator
extends AbstractByteSpliterator
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 is only appropriate for sequences that are at most Integer.MAX_VALUE long. If your backing data store can be bigger then this, consider the equivalently named class in the type specific BigSpliterators class.

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).

      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.
