public static interface Spliterator.OfDouble implements OfPrimitive<Double, DoubleConsumer, Spliterator.OfDouble>

Known Indirect Subclasses

Spliterators.AbstractDoubleSpliterator

A Spliterator specialized for double values.

Inherited Constant Summary

From interface java.util.Spliterator

int	CONCURRENT	Characteristic value signifying that the element source may be safely concurrently modified (allowing additions, replacements, and/or removals) by multiple threads without external synchronization.
int	DISTINCT	Characteristic value signifying that, for each pair of encountered elements `x, y`, `!x.equals(y)`.
int	IMMUTABLE	Characteristic value signifying that the element source cannot be structurally modified; that is, elements cannot be added, replaced, or removed, so such changes cannot occur during traversal.
int	NONNULL	Characteristic value signifying that the source guarantees that encountered elements will not be `null`.
int	ORDERED	Characteristic value signifying that an encounter order is defined for elements.
int	SIZED	Characteristic value signifying that the value returned from `estimateSize()` prior to traversal or splitting represents a finite size that, in the absence of structural source modification, represents an exact count of the number of elements that would be encountered by a complete traversal.
int	SORTED	Characteristic value signifying that encounter order follows a defined sort order.
int	SUBSIZED	Characteristic value signifying that all Spliterators resulting from `trySplit()` will be both `SIZED` and `SUBSIZED`.

Inherited Method Summary

From interface java.util.Spliterator.OfPrimitive

void	forEachRemaining(DoubleConsumer action) Performs the given action for each remaining element, sequentially in the current thread, until all elements have been processed or the action throws an exception.
abstract boolean	tryAdvance(DoubleConsumer action) If a remaining element exists, performs the given action on it, returning `true`; else returns `false`.
abstract T_SPLITR	trySplit() If this spliterator can be partitioned, returns a Spliterator covering elements, that will, upon return from this method, not be covered by this Spliterator.

From interface java.util.Spliterator

abstract int	characteristics() Returns a set of characteristics of this Spliterator and its elements.
abstract long	estimateSize() Returns an estimate of the number of elements that would be encountered by a `forEachRemaining(Consumer)` traversal, or returns `Long.MAX_VALUE` if infinite, unknown, or too expensive to compute.
void	forEachRemaining(Consumer<? super T> action) Performs the given action for each remaining element, sequentially in the current thread, until all elements have been processed or the action throws an exception.
Comparator<? super T>	getComparator() If this Spliterator's source is `SORTED` by a `Comparator`, returns that `Comparator`.
long	getExactSizeIfKnown() Convenience method that returns `estimateSize()` if this Spliterator is `SIZED`, else `-1`.
boolean	hasCharacteristics(int characteristics) Returns `true` if this Spliterator's `characteristics()` contain all of the given characteristics.
abstract boolean	tryAdvance(Consumer<? super T> action) If a remaining element exists, performs the given action on it, returning `true`; else returns `false`.
abstract Spliterator<Double>	trySplit() If this spliterator can be partitioned, returns a Spliterator covering elements, that will, upon return from this method, not be covered by this Spliterator.

public abstract Spliterator.OfDouble trySplit ()

If this spliterator can be partitioned, returns a Spliterator covering elements, that will, upon return from this method, not be covered by this Spliterator.

If this Spliterator is ORDERED, the returned Spliterator must cover a strict prefix of the elements.

Unless this Spliterator covers an infinite number of elements, repeated calls to trySplit() must eventually return null. Upon non-null return:

the value reported for estimateSize() before splitting, must, after splitting, be greater than or equal to estimateSize() for this and the returned Spliterator; and
if this Spliterator is SUBSIZED, then estimateSize() for this spliterator before splitting must be equal to the sum of estimateSize() for this and the returned Spliterator after splitting.

This method may return null for any reason, including emptiness, inability to split after traversal has commenced, data structure constraints, and efficiency considerations.

Returns

a Spliterator covering some portion of the elements, or null if this spliterator cannot be split
