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 Function3 is used by injectIntoWith(). In the injectIntoWith() method the block takes the injected
argument as the first argument, the current item of the collection as the second argument, and the specified
parameter for the third argument. The result of each subsequent iteration is passed in as the first argument.
