Public methods

forEachRemaining

Added in API level 24
void forEachRemaining (LongConsumer action)

对每个剩余元素执行给定操作,直到处理完所有元素或操作抛出异常。 如果指定了该顺序,则按迭代顺序执行操作。 该操作引发的异常会中继给调用者。

实现要求:
  • 默认实现的行为如下:

    while (hasNext())
             action.accept(nextLong());
     
Parameters
action LongConsumer: The action to be performed for each element
Throws
NullPointerException if the specified action is null

forEachRemaining

Added in API level 24
void forEachRemaining (Consumer<? super Long> action)

实现要求:
  • If the action is an instance of LongConsumer then it is cast to LongConsumer and passed to forEachRemaining(T_CONS); otherwise the action is adapted to an instance of LongConsumer, by boxing the argument of LongConsumer, and then passed to forEachRemaining(T_CONS).
Parameters
action Consumer

next

Added in API level 24
Long next ()

返回迭代中的下一个元素。

实现要求:
  • The default implementation boxes the result of calling nextLong(), and returns that boxed result.
Returns
Long the next element in the iteration

nextLong

Added in API level 24
long nextLong ()

返回迭代中的下一个 long元素。

Returns
long the next long element in the iteration
Throws
NoSuchElementException if the iteration has no more elements

Hooray!
