Class IfExprVarCharScalarStringGroupColumn

java.lang.Object

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.IfExprStringScalarStringGroupColumn

org.apache.hadoop.hive.ql.exec.vector.expressions.IfExprVarCharScalarStringGroupColumn

All Implemented Interfaces:

Serializable

public class IfExprVarCharScalarStringGroupColumn
extends IfExprStringScalarStringGroupColumn

Compute IF(expr1, expr2, expr3) for 3 input column expressions. The first is always a boolean (LongColumnVector). The second is a string scalar. The third is a string column or non-constant expression result.
