Barcode

org.appliedtopology.tda4j.barcode.Barcode
object Barcode

Stateless: every method here is a pure function of its arguments, so this is an object, not a class you instantiate per call (as it was before, Barcode[F, A]().method(...), with no state ever carried between the construction and the one call).
