PrimitiveIterator.OfDouble

public static interface PrimitiveIterator.OfDouble
implements PrimitiveIterator<Double, DoubleConsumer>

java.util.PrimitiveIterator.OfDouble

一个专门用于 double值的Iterator。

Summary

Public methods
default void forEachRemaining(Consumer<? super Double> action)

default void forEachRemaining(DoubleConsumer 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。
default Double next()

返回迭代中的下一个元素。
abstract double nextDouble()

返回迭代中的下一个 double元素。

Public methods

forEachRemaining

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

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

forEachRemaining

Added in API level 24 
void forEachRemaining (DoubleConsumer 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(nextDouble());
Parameters
action DoubleConsumer: The action to be performed for each element
Throws
NullPointerException if the specified action is null

next

Added in API level 24 
Double next ()

返回迭代中的下一个元素。

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

nextDouble

Added in API level 24 
double nextDouble ()

返回迭代中的下一个 double元素。

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