public class DefaultValueHelper
extends Object

Assigns the defined default value(s). This class is intended to support interactive configuration. Otherwise, please rely on the reasoning capabilities. Instances of this class are intended for reuse, so call initialize(IDecisionVariable) before use (alternatively DefaultValueHelper(IDecisionVariable) for creation) and clear() after use.
