PrimitiveIterator
public
interface
PrimitiveIterator
implements
Iterator<T>
java.util.PrimitiveIterator<T, T_CONS> |
A base type for primitive specializations of Iterator
. Specialized
subtypes are provided for int
, long
, and
double
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
next()
and
forEachRemaining()
,
does not affect the order in which the values, transformed to boxed values,
are encountered.

forEachRemaining
public abstract void forEachRemaining (T_CONS 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
source of elements 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.
