PrimitiveIterator
implements
Iterator<T>
java.util.PrimitiveIterator<T, T_CONS> |
Known Indirect Subclasses |
A base type for primitive specializations of Iterator
. Specialized
subtypes are provided for int
, long
, and
double
values.
The specialized subtype default implementations of next()
and 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, nextInt()
and
forEachRemaining(java.util.function.IntConsumer)
should be used in preference to next()
and
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.

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.
