Field Summary

Fields declared in interface Spliterator

CONCURRENT, DISTINCT, IMMUTABLE, NONNULL, ORDERED, SIZED, SORTED, SUBSIZED

Modifier and Type	Field	Description
static final 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.
static final int	DISTINCT	Characteristic value signifying that, for each pair of encountered elements x, y, !x.equals(y).
static final 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.
static final int	NONNULL	Characteristic value signifying that the source guarantees that encountered elements will not be null.
static final int	ORDERED	Characteristic value signifying that an encounter order is defined for elements.
static final 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.
static final int	SORTED	Characteristic value signifying that encounter order follows a defined sort order.
static final int	SUBSIZED	Characteristic value signifying that all Spliterators resulting from trySplit() will be both Spliterator.SIZED and Spliterator.SUBSIZED.

Method Summary

Modifier and Type	Method	Description
default void	forEachRemaining(Consumer<? super Double> 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.
default boolean	tryAdvance(Consumer<? super Double> action)	If a remaining element exists: performs the given action on it, returning true; else returns false.

Methods declared in interface Spliterator

characteristics, estimateSize, getComparator, getExactSizeIfKnown, hasCharacteristics, trySplit

Modifier and Type	Method	Description
int	characteristics()	Returns a set of characteristics of this Spliterator and its elements.
long	estimateSize()	Returns an estimate of the number of elements that would be encountered by a Spliterator.forEachRemaining(Consumer) traversal, or returns Long.MAX_VALUE if infinite, unknown, or too expensive to compute.
default Comparator<? super Double>	getComparator()	If this Spliterator's source is Spliterator.SORTED by a Comparator, returns that Comparator.
default long	getExactSizeIfKnown()	Convenience method that returns Spliterator.estimateSize() if this Spliterator is Spliterator.SIZED, else -1.
default boolean	hasCharacteristics(int characteristics)	Returns true if this Spliterator's Spliterator.characteristics() contain all of the given characteristics.
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.

Methods declared in interface Spliterator.OfPrimitive

forEachRemaining, tryAdvance

Modifier and Type	Method	Description
default 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.
boolean	tryAdvance(DoubleConsumer action)	If a remaining element exists, performs the given action on it, returning true; else returns false.

Method Details

tryAdvance

default boolean tryAdvance(Consumer<? super Double> action)

If a remaining element exists: performs the given action on it, returning true; else returns false. If this Spliterator is Spliterator.ORDERED the action is performed on the next element in encounter order. Exceptions thrown by the action are relayed to the caller.

Subsequent behavior of a spliterator is unspecified if the action throws an exception.

Specified by:

tryAdvance in interface Spliterator<Double>

Implementation Requirements:

If the action is an instance of DoubleConsumer then it is cast to DoubleConsumer and passed to Spliterator.OfPrimitive.tryAdvance(java.util.function.DoubleConsumer); otherwise the action is adapted to an instance of DoubleConsumer, by boxing the argument of DoubleConsumer, and then passed to Spliterator.OfPrimitive.tryAdvance(java.util.function.DoubleConsumer).

Parameters:

action - The action whose operation is performed at-most once

Returns:

false if no remaining elements existed upon entry to this method, else true.

forEachRemaining

default void forEachRemaining(Consumer<? super Double> 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. If this Spliterator is Spliterator.ORDERED, actions are performed in encounter order. Exceptions thrown by the action are relayed to the caller.

Subsequent behavior of a spliterator is unspecified if the action throws an exception.

Specified by:

forEachRemaining in interface Spliterator<Double>

Implementation Requirements:

If the action is an instance of DoubleConsumer then it is cast to DoubleConsumer and passed to Spliterator.OfPrimitive.forEachRemaining(java.util.function.DoubleConsumer); otherwise the action is adapted to an instance of DoubleConsumer, by boxing the argument of DoubleConsumer, and then passed to Spliterator.OfPrimitive.forEachRemaining(java.util.function.DoubleConsumer).

Parameters:

action - The action
