public class TriMap<T1,T2,T3> extends java.lang.Object
TriMap is a triple-directional map. It is intended to hold items, T1, T2, and T3, that have a 1-1 relationship and it is desired to look up item T1 from T2 or T3, T2 from T1 or T2, or T3 from T1 or T2. If a new item is inserted that already exists in the map the add will fail

entrySet
public java.util.Set<TriMap.Entry<T1,T2,T3>> entrySet()
entrySet returns a Set of Entry objects from the tri-maps. It is intended to be used when iterating over the tri-maps. It works very similarly (same syntax) as the HashMap.entrySet(). However, the returned Set is independent of the contents of the tri-map. Thus, if you modify the returned Set, you will NOT modify the underlying tri-maps
