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 PartitionMutableCollection is the result of splitting a mutable collection into two mutable collections 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.
