示例1: handleDefaultChild
import org.dmg.pmml.tree.Node; //导入方法依赖的package包/类
private Trail handleDefaultChild(Trail trail, Node node, EvaluationContext context){
// "The defaultChild missing value strategy requires the presence of the defaultChild attribute in every non-leaf Node"
String defaultChild = node.getDefaultChild();
if(defaultChild == null){
throw new MissingAttributeException(node, PMMLAttributes.NODE_DEFAULTCHILD);
