Interface Unmodifiable
- All Known Implementing Classes:
- UnmodifiableBag,- UnmodifiableBidiMap,- UnmodifiableBoundedCollection,- UnmodifiableCollection,- UnmodifiableEntrySet,- UnmodifiableIterator,- UnmodifiableList,- UnmodifiableListIterator,- UnmodifiableMap,- UnmodifiableMapEntry,- UnmodifiableMapIterator,- UnmodifiableMultiSet,- UnmodifiableMultiValuedMap,- UnmodifiableNavigableSet,- UnmodifiableOrderedBidiMap,- UnmodifiableOrderedMap,- UnmodifiableOrderedMapIterator,- UnmodifiableQueue,- UnmodifiableSet,- UnmodifiableSortedBag,- UnmodifiableSortedBidiMap,- UnmodifiableSortedMap,- UnmodifiableSortedSet,- UnmodifiableTrie
public interface Unmodifiable
Marker interface for collections, maps and iterators that are unmodifiable.
 
This interface enables testing such as:
 if (coll instanceof Unmodifiable) {
   coll = new ArrayList(coll);
 }
 // now we know coll is modifiable
 
 
 Of course all this only works if you use the Unmodifiable classes defined
 in this library. If you use the JDK unmodifiable class via java.util Collections
 then the interface won't be there.
