Class Unmodifiables.UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableEntry<K,V>
java.lang.Object
bb.util.Unmodifiables.UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableEntry<K,V>
- All Implemented Interfaces:
- Map.Entry<K,V>
- Enclosing class:
- Unmodifiables.UnmodifiableMap.UnmodifiableEntrySet<K,V>
private static class Unmodifiables.UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableEntry<K,V>
- extends Object
- implements 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.
