Class CastLongToDecimal

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

All Implemented Interfaces:

Serializable

public class CastLongToDecimal
extends FuncLongToDecimal

To be used to cast long and boolean to decimal. This works for boolean too because boolean is encoded as 0 for false and 1 for true.
