Hi,
Re: Bugzilla [Bug 12227]
FYI, this patch implements "pipeline-hints" as discussed on cocoon-dev
mailing-list.
Breifly, "pipeline-hints" is the ability to provide
"hints" to pipelines to indicate that certain behavior
is desired when adding a pipeline-component to the pipeline. This hint
takes the form of an extra "hintParam" Parameters Object in the "set" and
"add" methods of the ProcessingPipeline interface.
This patch provides a first stage implementation (and does yet fully
implement the planned syntax as Proposed by Sylvain Wallez below). But
can easily be extended to do so.
This patch also alters the caching-point pipeline implementation so that
it accepts caching-points "hints" to indicate manual caching points!
so that <map:transform src="../simple-samples2html.xsl" hint="caching-point"/>
will hint to the pipleline that this is a manual caching point.
Of course, pipeline implementations which do not support certain hints
silently ignore them.
What do you guys think?
Regards,
Michael Melhem
