new de2ae7fd3d Reorganizes MetadataConstraints (#4852)
de2ae7fd3d is described below
commit de2ae7fd3dc1b8b39e012c213b9c9e05dd78509e
Author: Kevin Rathbun <krath...@apache.org>
AuthorDate: Mon Sep 16 10:26:00 2024 -0400
Reorganizes MetadataConstraints (#4852)
- new class `BulkFileColData` to store the data needed to validate a
BulkFileColumn update
Changes to check():
- now uses switch instead of if
- validation logic of each column now done in separate methods
- removed unnecessary checks and simplified logic where applicable (e.g.,
if checks that would never be true, same check done more than once)
- violations are no longer added to and returned by `validate` methods,
only added to. Avoids confusion with how the methods should be used.
- initialized violations at start as a list instead of dealing with
null. Null added extra unnecessary complexity.
