CustomShadowVariableDemand (OptaPlanner distribution 8.10.0.Final API)

java.lang.Object
- org.optaplanner.core.impl.domain.variable.custom.CustomShadowVariableDemand<Solution_>

All Implemented Interfaces:

Demand<Solution_,SingletonInverseVariableSupply>
```
public class CustomShadowVariableDemand<Solution_>
extends Object
implements Demand<Solution_,SingletonInverseVariableSupply>
```
Unlike other Demands, a custom demand isn't equalized based on its sources, but based on its target. Therefore a custom shadow variable cannot be reused by built-in systems.
