## Class CustomShadowVariableDemand

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

- All Implemented Interfaces:
    Demand<SingletonInverseVariableSupply>

      public class CustomShadowVariableDemand
      extends Object
      implements Demand<SingletonInverseVariableSupply>

  Unlike other `Demand`s, 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.
