https://github.com/eclipse/eclipse-collections/eclipse-collections-api: Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API and set of utility classes that work with any JDK compatible Collections, Arrays, Maps or Strings. The iteration protocol was inspired by the Smalltalk collection framework.

A PartitionIterable is the result of splitting an iterable into two iterables based on a Predicate.  The results that
answer true for the Predicate will be returned from the getSelected() method and the results that answer false for the
predicate will be returned from the getRejected() method.
