- org.opendaylight.yangtools.util.UnmodifiableMap<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Implemented Interfaces:

Map<K,V>, Immutable, MutationBehaviour<Immutable>
```
@Beta
public final class UnmodifiableMap<K,V>
extends Object
implements Map<K,V>, Immutable
```
An unmodifiable view over a Map. Unlike the view returned via Collections.unmodifiableMap(Map), this class checks its argument to ensure multiple encapsulation does not occur.
This class checks the argument so it prevents multiple encapsulation. Subclasses of ImmutableMap are also recognized and not encapsulated.

public static <K,V> @NonNull Map<K,V> of(@NonNull Map<K,V> map)
```
    Create an unmodifiable view of the target Map. If the map is known to be unmodifiable, that same instance is returned. Otherwise an unmodifiable view of the map will be returned.
    
    Parameters:
    
    map - Target map
    
    Returns:
    
    An unmodifiable view of the map
    
    Throws:
    
    NullPointerException - if map is null
