StatefulVariableListener (OptaPlanner distribution 7.71.0.Final API)

All Superinterfaces:

AutoCloseable, Closeable, Supply, VariableListener<Entity_>, VariableListener<Entity_>

All Known Subinterfaces:

SourcedVariableListener<Entity_>

All Known Implementing Classes:

ExternalizedAnchorVariableSupply, ExternalizedCollectionInverseVariableSupply, ExternalizedSingletonInverseVariableSupply
```
@Deprecated
public interface StatefulVariableListener<Entity_>
extends VariableListener<Entity_>
```
Deprecated.
VariableListener can now be stateful too.

A stateful VariableListener, often used to externalize data for a Supply from the domain model itself.
