private static class Collections.UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableEntry

extends Object

implements Map.Entry

This "wrapper class" serves two purposes: it prevents the client from modifying the backing Map, by short-circuiting the setValue method, and it protects the backing Map against an ill-behaved Map.Entry that attempts to modify another Map Entry when asked to perform an equality check.
