trySplit

Spliterator.OfDouble trySplit()

从接口复制的说明: 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.

指定者:

trySplit 在接口中 Spliterator<Double>

指定者:

trySplit 在接口中 Spliterator.OfPrimitive<Double,DoubleConsumer,Spliterator.OfDouble>

返回:

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

tryAdvance

boolean tryAdvance(DoubleConsumer action)

从接口复制的说明: 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.

指定者:

tryAdvance 在接口中 Spliterator.OfPrimitive<Double,DoubleConsumer,Spliterator.OfDouble>

参数:

action - The action

返回:

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

forEachRemaining

default void forEachRemaining(DoubleConsumer action)

从接口复制的说明: 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.

指定者:

forEachRemaining 在接口中 Spliterator.OfPrimitive<Double,DoubleConsumer,Spliterator.OfDouble>

参数:

action - The action

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.

指定者:

tryAdvance 在接口中 Spliterator<Double>

参数:

action - The action

返回:

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.

指定者:

forEachRemaining 在接口中 Spliterator<Double>

参数:

action - The action
