Methods

Modifier and Type Method Description
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.
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.
default Double next()

Returns the next element in the iteration.
double nextDouble()

Returns the next double element in the iteration.

Methods declared in interface java.util.Iterator

hasNext, remove

Methods

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 interface PrimitiveIterator<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 interface Iterator<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 interface Iterator<Double>
Implementation Requirements:
If the action is an instance of DoubleConsumer then it is cast to DoubleConsumer and passed to forEachRemaining(java.util.function.DoubleConsumer); otherwise the action is adapted to an instance of DoubleConsumer, by boxing the argument of DoubleConsumer, and then passed to forEachRemaining(java.util.function.DoubleConsumer).
Parameters:
action - The action to be performed for each element
