示例1: BNLJoinExec
import org.apache.tajo.engine.planner.logical.JoinNode; //導入方法依賴的package包/類
public BNLJoinExec(final TaskAttemptContext context, final JoinNode plan,
final PhysicalExec leftExec, PhysicalExec rightExec) {
super(context, plan.getInSchema(), plan.getOutSchema(), leftExec, rightExec);
this.plan = plan;
this.joinQual = plan.getJoinQual();
if (joinQual != null) { // if join type is not 'cross join'
