void |
IntStream.IntMapMultiConsumer.accept(int value,
IntConsumer ic)
Replaces the given
value with zero or more values by feeding the mapped
values to the ic consumer. |
void |
IntStream.forEach(IntConsumer action)
Performs an action for each element of this stream.
|
void |
IntStream.forEachOrdered(IntConsumer action)
Performs an action for each element of this stream, guaranteeing that
each element is processed in encounter order for streams that have a
defined encounter order.
|
IntStream |
IntStream.peek(IntConsumer action)
Returns a stream consisting of the elements of this stream, additionally
performing the provided action on each element as elements are consumed
from the resulting stream.
