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