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).

Description copied from interface:IntSpliterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling
IntSpliterator.tryAdvance(java.util.function.Consumer<? super java.lang.Integer>)
forn
times (possibly stopping ifIntSpliterator.tryAdvance(java.util.function.Consumer<? super java.lang.Integer>)
returns false). The action called will do nothing; elements will be discarded.- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
Spliterator.tryAdvance(java.util.function.Consumer<? super T>)
-
trySplit
public IntSpliterator trySplit()
- Throws:
java.lang.IndexOutOfBoundsException
- if the return ofcomputeSplitPoint()
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 whatgetMaxPos()
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.
