Class ColOrCol

java.lang.Object
  org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression
      org.apache.hadoop.hive.ql.exec.vector.expressions.ColOrCol

All Implemented Interfaces:

Serializable

public class ColOrCol
extends VectorExpression

This class performs OR expression on two input columns and stores, the boolean output in a separate output column. The boolean values are supposed to be represented as 0/1 in a long vector.
