> Make subclassing a PK Generator easier
> --------------------------------------
>
> Key: CAY-2889
> URL: https://issues.apache.org/jira/browse/CAY-2889
> Project: Cayenne
> Issue Type: Improvement
> Components: Core Library
> Reporter: Michael Ray Gentry
> Priority: Minor
> Fix For: Undefined future
>
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> The *{{MySQLPkGenerator}}* makes two *{{super}}* calls that make subclassing
> more difficult:
> # super.pkSelectString(entityName)
> # super.pkUpdateString(entityName)
> The *{{super.}}* prefix should be removed to make it easier to subclass
> *{{MySQLPkGenerator}}* since *{{pkSelectString}}* and *{{pkUpdateString}}*
> are only implemented in the superclass ({*}{{JdbcPkGenerator}}{*}) and will
> get called by default since *{{MySQLPkGenerator}}* lacks those methods, but
> if someone subclasses *{{MySQLPkGenerator}}* and adds *{{pkSelectString}}*
> and/or *{{pkUpdateString}}* then the custom subclass methods will handle that
> logic instead of *{{JdbcPkGenerator}}* once the *{{super.}}* prefix is
> removed.
> See the developer mailing list conversation started by Robert Decker on April
> 30, 2025.
> Additionally, check the other PK Generator classes to see if they suffer from
> this issue.
