Class LongScalarDivideLongColumn

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

All Implemented Interfaces:

Serializable

public class LongScalarDivideLongColumn
extends VectorExpression

This operation is handled as a special case because Hive long/long division returns double. This file is thus not generated from a template like the other arithmetic operations are.
