Methods

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

Methods

trySplit

Spliterator.OfDouble trySplit()

Description copied from interface: Spliterator

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 Spliterator.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.

Specified by:: trySplit in interface Spliterator<Double>
Specified by:: trySplit in interface Spliterator.OfPrimitive<Double,DoubleConsumer,Spliterator.OfDouble>
Returns:: a Spliterator covering some portion of the elements, or null if this spliterator cannot be split

tryAdvance

boolean tryAdvance(DoubleConsumer action)

Description copied from interface: Spliterator.OfPrimitive

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.

Specified by:: tryAdvance in interface Spliterator.OfPrimitive<Double,DoubleConsumer,Spliterator.OfDouble>
Parameters:: action - The action
Returns:: false if no remaining elements existed upon entry to this method, else true.

forEachRemaining

default void forEachRemaining(DoubleConsumer action)

Description copied from interface: Spliterator.OfPrimitive

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.

Specified by:: forEachRemaining in interface Spliterator.OfPrimitive<Double,DoubleConsumer,Spliterator.OfDouble>
Parameters:: action - The action

tryAdvance

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

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 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 tryAdvance(java.util.function.DoubleConsumer).
Parameters:: action - The action
Returns:: false if no remaining elements existed upon entry to this method, else true.

forEachRemaining

default void forEachRemaining(Consumer<? super Double> action)

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 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 forEachRemaining(java.util.function.DoubleConsumer).
Parameters:: action - The action
