Summary
| Public methods |
| open Unit |
Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
|
| open Unit |
Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
|
| open Long! |
Returns the next element in the iteration.
|
| abstract Long |
Returns the next long element in the iteration.

Public methods
forEachRemaining
open fun forEachRemaining(action: Consumer<in Long!>): Unit
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 collection 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.
| Parameters |
action |
Consumer<in Long!>: The action to be performed for each element |
| Exceptions |
java.lang.NullPointerException |
if the specified action is null |
forEachRemaining
open fun forEachRemaining(action: LongConsumer!): Unit
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 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.
| Parameters |
action |
LongConsumer!: The action to be performed for each element |
| Exceptions |
java.lang.NullPointerException |
if the specified action is null |
next
open fun next(): Long!
Returns the next element in the iteration.
| Return |
Long! |
the next element in the iteration |
| Exceptions |
java.util.NoSuchElementException |
if the iteration has no more elements |
nextLong
abstract fun nextLong(): Long
Returns the next long element in the iteration.
| Return |
Long |
the next long element in the iteration |
| Exceptions |
java.util.NoSuchElementException |
if the iteration has no more elements |
