Interface Spliterator.OfPrimitive<T, T_CONS, T_SPLITR extends Spliterator.OfPrimitive<T,T_CONS,T_SPLITR>>

Type Parameters:
T - the type of elements returned by this Spliterator. The type must be a wrapper type for a primitive type, such as Integer for the primitive int type.
T_CONS - the type of primitive consumer. The type must be a primitive specialization of Consumer for T, such as IntConsumer for Integer.
T_SPLITR - the type of primitive Spliterator. The type must be a primitive specialization of Spliterator for T, such as Spliterator.OfInt for Integer.
All Superinterfaces:
Spliterator<T>
All Known Subinterfaces:
Spliterator.OfDouble, Spliterator.OfInt, Spliterator.OfLong
All Known Implementing Classes:
Spliterators.AbstractDoubleSpliterator, Spliterators.AbstractIntSpliterator, Spliterators.AbstractLongSpliterator
Enclosing interface:
Spliterator<T>
public static interface Spliterator.OfPrimitive<T, T_CONS, T_SPLITR extends Spliterator.OfPrimitive<T,T_CONS,T_SPLITR>> extends Spliterator<T>
A Spliterator specialized for primitive values.

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(T_CONS 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(T_CONS action)
If a remaining element exists, performs the given action on it, returning true; else returns false.

Methods declared in interface Spliterator

characteristics, estimateSize, forEachRemaining, getComparator, getExactSizeIfKnown, hasCharacteristics, tryAdvance, 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 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.
default Comparator<? super T> 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.
boolean tryAdvance(Consumer<? super T> action)
If a remaining element exists: performs the given action on it, returning true; else returns false.
Spliterator<T> 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.

Method Details

tryAdvance

boolean tryAdvance(T_CONS 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.

Parameters:
action - The action
Returns:
false if no remaining elements existed upon entry to this method, else true.
Throws:
NullPointerException - if the specified action is null

forEachRemaining

default void forEachRemaining(T_CONS 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.

Implementation Requirements:
The default implementation repeatedly invokes tryAdvance(T_CONS) until it returns false. It should be overridden whenever possible.
Parameters:
action - The action
Throws:
NullPointerException - if the specified action is null
