FastStream
If true is specified to consumeToCalculate causes
operations which would not normally know their length prior to a
terminal operation being applied, to cache their result under the assumption
that the stream is about to be fully consumed.
knownLength in interface FastStream<V>consumeToCalculate - If the caller intends to consume the entire stream via Iterable.forEach(java.util.function.Consumer<? super T>) after calling.public K getKey()
public V[] toArray(V[] arr)
FastStreamT[].toArray in interface FastStream<V>arr - The template array to use. If the array is large enough
to fit all elements in the stream, this will be used with
a single null element after the last element.T[].
