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 BiMap API.


     A BiMap is a map that allows users to look up key-value pairs from either direction. Uniqueness is enforced on both the keys and values.


    This package contains 3 interfaces:

    
    
  •  BiMap - contains the common API for Mutable and Immutable BiMap. 
    • 
    
  •  MutableBiMap - a BiMap whose contents can be altered after initialization. 
    • 
    
  •  ImmutableBiMap - a BiMap whose contents cannot be altered after initialization.
