WebIn the inheritance hierarchy below Iterable you find three traits: Seq, Set, and Map. Seq and Map implement the PartialFunction trait with its apply and isDefinedAt methods, each implemented differently. Set gets its apply method from GenSetLike.. For sequences, apply is positional indexing, where elements are always numbered from 0.That is, Seq(1, 2, …
