Class FXCollections.CheckedObservableMap.CheckedEntrySet.CheckedEntry<K,V,T>

java.lang.Object

javafx.collections.FXCollections.CheckedObservableMap.CheckedEntrySet.CheckedEntry<K,V,T>

All Implemented Interfaces:

java.util.Map.Entry<K,V>

Enclosing class:

FXCollections.CheckedObservableMap.CheckedEntrySet<K,V>

private static class FXCollections.CheckedObservableMap.CheckedEntrySet.CheckedEntry<K,V,T>
extends java.lang.Object
implements java.util.Map.Entry<K,V>

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.
