Uses of IntFunction in java.util.stream
Modifier and TypeMethodDescriptionIntStream.flatMap
(IntFunction<? extends IntStream> mapper) Returns a stream consisting of the results of replacing each element of this stream with the contents of a mapped stream produced by applying the provided mapping function to each element.<U> Stream<U>
IntStream.mapToObj
(IntFunction<? extends U> mapper) Returns an object-valuedStream
consisting of the results of applying the given function to the elements of this stream.<A> A[]
Stream.toArray
(IntFunction<A[]> generator) Returns an array containing the elements of this stream, using the providedgenerator
function to allocate the returned array, as well as any additional arrays that might be required for a partitioned execution or for resizing.
