public class UnifiedMapWithHashingStrategy<K,V> extends AbstractMutableMap<K,V> implements Externalizable, BatchIterable<V>
The difference between UnifiedMap and UnifiedMapWithHashingStrategy is that a HashingStrategy based UnifiedMap does not rely on the hashCode or equality of the object at the key, but instead relies on a HashingStrategy implementation provided by a developer to compute the hashCode and equals for the objects stored in the map.
Constructor | Description |
---|---|
UnifiedMapWithHashingStrategy() |
Deprecated.
No argument default constructor used for serialization. Instantiating an UnifiedMapWithHashingStrategyMultimap with
this constructor will have a null hashingStrategy and throw NullPointerException when used.
