PartAndFilterExprRewriter (TiKV Java Client 3.3.5 API)

```
public class PartAndFilterExprRewriter
extends DefaultVisitor<Expression,Void>
```
PartAndFilterExprRewriter takes partition expression as an input. Rewriting rule is based on the type of partition expression. 1. If partition expression is a columnRef, no rewriting will be performed. 2. If partition expression is year and the expression to be rewritten in the form of y < '1995-10-10' then its right hand child will be replaced with "1995". 3. If partition expression is year and the expression to be rewritten in the form of year(y) < '1995' then its left hand child will be replaced with y.
