Interface Bind.MapWithModificationListener<K,V>

Type Parameters:

K - key type in map

V - value type in map

All Superinterfaces:

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

All Known Implementing Classes:

BTreeMap, HTreeMap

Enclosing class:

Bind

public static interface Bind.MapWithModificationListener<K,V>
extends ConcurrentMap<K,V>

Primary Maps must provide notifications when it is modified. So Primary Maps must implement this interface to allow registering callback listeners.
