Modifier and Type	Class and Description
private static class	FXCollections.CheckedObservableMap.CheckedEntrySet.CheckedEntry<K,V,T> 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.
