> Issue Type: Improvement

> Reporter: Diego Ceccarelli
> Priority: Minor
> Fix For: 7.0
>
>
> This patch -adds a {{prepare}} and a {{finish}} method to the interface of
> {{DocTransformer}}- allowing a developer to perform actions before/after a
> doc transformer is applied to a result set. My use case was to benchmark the
> performance of a transformer, since transformer time is not part of
> {{QTime}}.
