    • isInitialized

      public abstract boolean isInitialized(Object entity)
      A nullable planning variable and PlanningListVariable are always considered initialized.
      Parameters:
      entity - never null
      Returns:
      true if the variable on that entity is initialized

    • isGenuineAndUninitialized

      public boolean isGenuineAndUninitialized(Object entity)
      Specified by:
      isGenuineAndUninitialized in class VariableDescriptor<Solution_>

    • isReinitializable

      public boolean isReinitializable(Object entity)
      Decides whether an entity is eligible for initialization. This is not an opposite of isInitialized() because even a PlanningVariable.nullable() variable, which is always considered initialized, is reinitializable if its value is null.
