Method Detail
-
nextLong
long nextLong()
Returns the nextlongelement in the iteration.- Returns:
- the next
longelement in the iteration - Throws:
NoSuchElementException- if the iteration has no more elements
-
forEachRemaining
default 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.- Specified by:
forEachRemainingin 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- Throws:
NullPointerException- if the specified action is null
-
next
default Long next()
Returns the next element in the iteration.- Specified by:
nextin 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)
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
removemethod or other mutator methods ofIteratorsubtypes), 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:
forEachRemainingin interfaceIterator<Long>- Implementation Requirements:
- If the action is an instance of
LongConsumerthen it is cast toLongConsumerand 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
