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

Direct Known Subclasses:

ScalarNullOrCol

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. The first input column field is reused from VectorExpression.
