The query execution engine creates proxy instances of that interface at runtime for each element returned and forwards calls to the exposed methods to the target object.
NOTE: Declaring a method in your `Repository` that overrides a base method (e.g. declared in `CrudRepository`, a store-specific repository interface, or the `Simple…Repository`) results in a call to the base method regardless of the declared return type.
