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.
