PrimitiveIterator
implements
Iterator<T>
java.util.PrimitiveIterator<T, T_CONS> |
A base type for primitive specializations of Iterator
. Specialized
subtypes are provided for OfInt
, OfLong
, and
OfDouble
values.
The specialized subtype default implementations of Iterator#next
and Iterator#forEachRemaining(java.util.function.Consumer)
box
primitive values to instances of their corresponding wrapper class. Such
boxing may offset any advantages gained when using the primitive
specializations. To avoid boxing, the corresponding primitive-based methods
should be used. For example, PrimitiveIterator.OfInt#nextInt()
and
PrimitiveIterator.OfInt#forEachRemaining(java.util.function.IntConsumer)
should be used in preference to PrimitiveIterator.OfInt#next()
and
PrimitiveIterator.OfInt#forEachRemaining(java.util.function.Consumer)
.
Iteration of primitive values using boxing-based methods
Iterator#next
and
Iterator#forEachRemaining(java.util.function.Consumer)
,
does not affect the order in which the values, transformed to boxed values,
are encountered.

forEachRemaining(T_CONS action)
Performs the given action for each remaining element, in the order elements occur when iterating, until all elements have been processed or the action throws an exception. |

public abstract void forEachRemaining (T_CONS action)
Performs the given action for each remaining element, in the order elements occur when iterating, until all elements have been processed or the action throws an exception. Errors or runtime exceptions thrown by the action are relayed to the caller.
