CopyOnWriteStateMap.StateMapEntry (Flink : Runtime 2.1.0 API)

java.lang.Object
- org.apache.flink.runtime.state.heap.CopyOnWriteStateMap.StateMapEntry<K,N,S>

Type Parameters:

K - type of key.

N - type of namespace.

S - type of state.

All Implemented Interfaces:

StateEntry<K,N,S>

Enclosing class:

CopyOnWriteStateMap<K,N,S>
```
@VisibleForTesting
protected static class CopyOnWriteStateMap.StateMapEntry<K,N,S>
extends Object
implements StateEntry<K,N,S>
```
One entry in the CopyOnWriteStateMap. This is a triplet of key, namespace, and state. Thereby, key and namespace together serve as a composite key for the state. This class also contains some management meta data for copy-on-write, a pointer to link other CopyOnWriteStateMap.StateMapEntrys to a list, and cached hash code.
