java.lang.Object

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

org.apache.hadoop.hive.ql.exec.vector.expressions.gen.IfExprTimestampScalarScalar

All Implemented Interfaces:

Serializable

public class IfExprTimestampScalarScalar
extends VectorExpression

Compute IF(expr1, expr2, expr3) for 3 input expressions. The first is always a boolean (LongColumnVector). The second is a constant value. The third is a constant value.
