java.lang.Object
io.github.kosmx.emotes.common.tools.BiMap<L,R>
Type Parameters:
L -
R -
All Implemented Interfaces:
Iterable<it.unimi.dsi.fastutil.Pair<L,R>>, Collection<it.unimi.dsi.fastutil.Pair<L,R>>
public class BiMap<L,R> extends Object implements Collection<it.unimi.dsi.fastutil.Pair<L,R>>
Bi-directional hash-map. Both L and R has to implement Object.hashCode() and Object.equals(Object) functions it can not be checked automatically, but DON'T forget it
