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
