OrderedMapAdapter(Map<Object, Object>): void
https://github.com/eclipse/eclipse-collections/eclipse-collections: 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.
