PrimitiveIterator.OfLong

AI-generated Key Takeaways

• PrimitiveIterator.OfLong is a specialized iterator for handling long values in Java.

• It provides methods like nextLong() to retrieve the next long element and forEachRemaining() to process remaining elements.

• This iterator inherits functionalities from PrimitiveIterator and Iterator interfaces, offering methods for iteration control and element access.

• nextLong() throws NoSuchElementException if there are no more elements, while forEachRemaining() can relay exceptions thrown by the provided action.

public static interface PrimitiveIterator.OfLong implements PrimitiveIterator<Long, LongConsumer>

An Iterator specialized for long values.

Public Method Summary

void	forEachRemaining(LongConsumer action) Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
void	forEachRemaining(Consumer<? super Long> action)
Long	next() Returns the next element in the iteration.
abstract long	nextLong() Returns the next long element in the iteration.

Inherited Method Summary

From interface java.util.PrimitiveIterator

abstract void

forEachRemaining(LongConsumer 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.

From interface java.util.Iterator

void	forEachRemaining(Consumer<? super E> action) Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
abstract boolean	hasNext() Returns true if the iteration has more elements.
abstract Long	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by this iterator (optional operation).

Public Methods

public void forEachRemaining (LongConsumer action)

Performs the given action for each remaining element until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration, if that order is specified. Exceptions thrown by the action are relayed to the caller.

Parameters

action	The action to be performed for each element

Throws

NullPointerException	if the specified action is null

public void forEachRemaining (Consumer<? super Long> action)

Parameters

action

public Long next ()

Returns the next element in the iteration.

Returns

• the next element in the iteration

public abstract long nextLong ()

Returns the next long element in the iteration.

Returns

• the next long element in the iteration

Throws

NoSuchElementException	if the iteration has no more elements
