示例1: BNLJoinExec
import org.apache.tajo.engine.planner.logical.JoinNode; //导入方法依赖的package包/类
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'
hasJoinQual = true;
} else {
hasJoinQual = false;
}
this.leftTupleSlots = new ArrayList<Tuple>(TUPLE_SLOT_SIZE);
this.rightTupleSlots = new ArrayList<Tuple>(TUPLE_SLOT_SIZE);
this.leftIterator = leftTupleSlots.iterator();
this.rightIterator = rightTupleSlots.iterator();
this.rightEnd = false;
this.leftEnd = false;
// for projection
