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.

This package contains interfaces for set API which enhance the performance and functionality of Set. 

     This package contains 6 interfaces:

    
  
  •  FixedSizeSet - a set that may be mutated, but cannot grow or shrink in size. 
    • 
  
  •  ImmutableSet - the non-modifiable equivalent interface to MutableSet. 
    • 
  
  •  MutableSet - an implementation of a JCF Set which provides internal iterator methods matching the Smalltalk Collection protocol. 
    • 
  
  •  Pool - locates an object in the pool which is equal to key. 
    • 
  
  •  SetIterable - a read-only Set API, with the minor exception inherited from Iterable (iterable.iterator().remove()). 
    • 
  
  •  UnsortedSetIterable - an iterable whose items are unique. 
    •
