JENA-1228: Expose each optimization transform step as a protected method.
> Allow application code to replace part of the standard "Optimize" sequence.
> ---------------------------------------------------------------------------
>
> Key: JENA-1228
> URL: https://issues.apache.org/jira/browse/JENA-1228
> Project: Apache Jena
> Issue Type: Improvement
> Reporter: Andy Seaborne
> Priority: Minor
>
> A different optimization step can be installed with a global change:
> {noformat}
> Optimize.setFactory((cxt)->new MyNewOptimize(cxt)) ;
> {noformat}
> or on a specific {{Context}}:
> {noformat}
> Optimize.RewriterFactory f = (cxt)->new OptimizeTQ(cxt) ;
> context.set(ARQConstants.sysOptimizerFactory, f) ;
> {noformat}
> This is a complete replacement.
> This JIRA is to allow specific steps to be replaced. This would be quite
> useful for development when specific transforms are being fixed or improved.
> One way to do this is to make {{Optimize}} have protected methods for each
> optimization step thereby exposing the standard policy with the possibility
> of different transforms within that policy.
> Thus:
> {noformat}
> class MyNewOptimize extends Optimize
> {noformat}
