> Improve type safety of RelJson API using generics
> -------------------------------------------------
>
> Key: CALCITE-7617
> URL: https://issues.apache.org/jira/browse/CALCITE-7617
> Project: Calcite
> Issue Type: Task
> Components: core
> Reporter: Stamatis Zampetakis
> Assignee: Stamatis Zampetakis
> Priority: Minor
> Fix For: 1.43.0
>
>
> The {{RelJson#typeNameToClass}} and {{RelJson#getConstructor}} APIs use raw
> types (Class, Constructor) leading to unchecked casts that may lead to
> unpredictable runtime failures.
> The APIs were meant to work only with sub-classes of the {{RelNode}}
> interface so we can improve type safety by introducing generic types in the
> signatures of the methods. Doing this the code becomes more safer & and more
> readable; redundant casts can be removed and various runtime crashes can now
> be caught during compilation.
> {{RelJson}} is an internal API so the change should not affect end-users.
