Combine filter and map in Xtend collections

Question

Given some iterable variable v and a type T I often find myself writing code such as

v.filter[it instanceof T].map[it as T]

Does there exist some helper which does the same functionality in a single step?

Answer 1

You may want to use v.filter(T) (or the legacy syntax v.filter(typeof(T))) which is Xtend's syntax for the Java equivalent v.filter(T.class).
