> Introduce a base abstract VectorExpression to eliminate further code
> duplications

> Key: HIVE-21465

> Project: Hive

>
> In vectorized expressions, from time to time, I see a similar/same logic to
> be repeated, which always consists of some stuff like:
> 1. some inner loops (even the comments are the same)
> {code}
> grep -iRH "Set isNull before call in case it changes it mind" | grep
> "ql/src/java/org/apache/hadoop/hive/ql/exec/vector/expressions/"
> {code}
> 2. call to an actual "business logic" function ==> 1 line which could be
> abstracted... and it has been abstracted in hive codebase in n different
> cases.
> However, an abstract BaseVectorExpression would not force anybody to extend
> it instead of VectorExpression and not copy the code again, but it could be a
> good start and an example.
