Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
(package private) final class	MildKeys.EntryItr	Iterator that iterates over reachable entries in the map.
(package private) final class	MildKeys.KeyItr	Iterator that iterates over reachable keys in the map.
(package private) static class	MildKeys.Soft<T>	Soft key that maintains a constant hash and uses referential equality.
