类 FilterOperator

java.lang.Object

org.apache.iotdb.spark.tsfile.qp.common.Operator

org.apache.iotdb.spark.tsfile.qp.common.FilterOperator

所有已实现的接口:

Comparable<FilterOperator>

直接已知子类:

BasicOperator

public class FilterOperator
extends Operator
implements Comparable<FilterOperator>

This class is for filter operator and implements Operator .
it may consist of more than two child FilterOperator, but if it's not leaf operator, the relation is same among all of its children.(AND or OR). It's identified by tokenType.
