PrimitiveIterator

public interface PrimitiveIterator
implements Iterator<T>

java.util.PrimitiveIterator<T, T_CONS>


A base type for primitive specializations of Iterator. Specialized subtypes are provided for int, long, and double values.

The specialized subtype default implementations of Iterator.next() and Iterator.forEachRemaining(java.util.function.Consumer) box primitive values to instances of their corresponding wrapper class. Such boxing may offset any advantages gained when using the primitive specializations. To avoid boxing, the corresponding primitive-based methods should be used. For example, PrimitiveIterator.OfInt.nextInt() and PrimitiveIterator.OfInt.forEachRemaining(java.util.function.IntConsumer) should be used in preference to PrimitiveIterator.OfInt.next() and Iterator.forEachRemaining(java.util.function.Consumer).

Iteration of primitive values using boxing-based methods next() and forEachRemaining(), does not affect the order in which the values, transformed to boxed values, are encountered.

Summary

Nested classes

interface PrimitiveIterator.OfDouble

An Iterator specialized for double values. 

interface PrimitiveIterator.OfInt

An Iterator specialized for int values. 

interface PrimitiveIterator.OfLong

An Iterator specialized for long values. 

Public methods

abstract void forEachRemaining(T_CONS action)

Performs the given action for each remaining element, in the order elements occur when iterating, until all elements have been processed or the action throws an exception.

Inherited methods

Public methods

forEachRemaining

added in API level 24
public abstract void forEachRemaining (T_CONS action)

Performs the given action for each remaining element, in the order elements occur when iterating, until all elements have been processed or the action throws an exception. Errors or runtime exceptions thrown by the action are relayed to the caller.

Parameters
action T_CONS: The action to be performed for each element

Throws
NullPointerException if the specified action is null
