Class ArrayMap<K,V>

java.lang.Object

com.jcabi.immutable.ArrayMap<K,V>

Type Parameters:

K - Map key type

V - Value key type

All Implemented Interfaces:

ConcurrentMap<K,V>, Map<K,V>

@Immutable
 @Loggable(value=1)
public final class ArrayMap<K,V>
extends Object
implements ConcurrentMap<K,V>

Map on top of array.

This class is truly immutable. This means that it never changes its encapsulated values and is annotated with @Immutable annotation.

Limitation: Encapsulated objects with exposed mutators can mutate their state.
