Method Summary

Modifier and Type	Method and Description
void	forEachRemaining(LongConsumer action) Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
Long	next() Implementation Requirements: The default implementation boxes the result of calling nextLong(), and returns that boxed result.
long	nextLong() Returns the next long element in the iteration.

Method Detail

nextLong

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

forEachRemaining

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.

The behavior of an iterator is unspecified if the action modifies the underlying source of elements in any way (even by calling the remove method or other mutator methods of Iterator subtypes), unless an overriding class has specified a concurrent modification policy.

Subsequent behavior of an iterator is unspecified if the action throws an exception.

Implementation Requirements:

The default implementation behaves as if:

     while (hasNext())
         action.accept(nextLong());
 

Specified by:

forEachRemaining in interface PrimitiveIterator<Long,LongConsumer>

Parameters:

action - The action to be performed for each element

Throws:

NullPointerException - if the specified action is null

next

Long next()

Implementation Requirements:
The default implementation boxes the result of calling nextLong(), and returns that boxed result.

Specified by:

next in interface Iterator<Long>
