Method Details
nextLong
long nextLong()
long
element in the iteration.- Returns:
- the next
long
element in the iteration - Throws:
-
NoSuchElementException
- if the iteration has no more elements
forEachRemaining
default void forEachRemaining(LongConsumer action)
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.
- Specified by:
-
forEachRemaining
in interfacePrimitiveIterator<Long,
LongConsumer> - Implementation Requirements:
-
The default implementation behaves as if:
while (hasNext()) action.accept(nextLong());
- Parameters:
-
action
- The action to be performed for each element
next
default Long next()
- Specified by:
-
next
in interfaceIterator<Long>
- Implementation Requirements:
- The default implementation boxes the result of calling
nextLong()
, and returns that boxed result. - Returns:
- the next element in the iteration
forEachRemaining
default void forEachRemaining(Consumer<? super Long> action)
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.
- Specified by:
-
forEachRemaining
in interfaceIterator<Long>
- Implementation Requirements:
- If the action is an instance of
LongConsumer
then it is cast toLongConsumer
and passed toforEachRemaining(java.util.function.LongConsumer)
; otherwise the action is adapted to an instance ofLongConsumer
, by boxing the argument ofLongConsumer
, and then passed toforEachRemaining(java.util.function.LongConsumer)
. - Parameters:
-
action
- The action to be performed for each element
