Class IntSpliterators.AbstractIndexBasedSpliterator
- All Implemented Interfaces:
IntSpliterator
,java.util.Spliterator<java.lang.Integer>
,java.util.Spliterator.OfInt
,java.util.Spliterator.OfPrimitive<java.lang.Integer,java.util.function.IntConsumer,java.util.Spliterator.OfInt>
- Direct Known Subclasses:
IntSpliterators.EarlyBindingSizeIndexBasedSpliterator
,IntSpliterators.LateBindingSizeIndexBasedSpliterator
- Enclosing class:
- IntSpliterators
public abstract static class IntSpliterators.AbstractIndexBasedSpliterator extends AbstractIntSpliterator
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).

skip
public long skip(long n)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
- 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.
