How to do common pipelines?
Hello,
Would like to use a pipeline, p, which is commonly used by other
pipelines, p1, p2, p3.
How could one achieve in p1, a call to common pipeline p, and then
continue the processing into pipeline.
(It sounds more like a functional call. In function parlance, it is
equivalent to a function calling another function within itself and
continuing forward after the function returns).
Thanks

Thanks David and Ross.
I could make the pipelines work. It works great!
For others, like me, here is a simplified explanation.
For making a common pipeline PipeP define:
<map:resource name="PipeP">
.... put your pipeline here....
</map:resource>
In the pipeline P1 or P2 or P3 then you can call:
<map:call name="PipeP"/>
anywhere in between
and it will execute the common pipline PipeP.
Good feature !
Praveen

As Ross said, see the Forrest core sitemaps,
e.g.
]$ cd $FORREST_HOME/main/webapp
]$ grep "map:call" *.xmap
There are many examples of this.
See the documentation about sitemaps
http://forrest.apache.org/docs/sitemap-explain.html
and others.
See "map:resource" to define various resources,
and then "map:call" to use them.

Ross,
I want to take this example to the next level.
Redirecting the pipeline at the top with map:generate does work.
How to do it in between too? So, from P1 I call pipeline P, transform with
mytest.xsl and then how do I call pipeline Q?
I would want something like this :
<map:match pattern="**P1.xml">
<map:generate src="cocoon:/P.xml"/>
<map:transform src="mytest.xsl"/>
<map:transform src="cocoon:/Q.xml"/>
<map:serialize type="xml"/>
</map:match>
<map:match pattern="Q.xml">
<map:generate src="test.xml"/>
<map:transform src="test2.xsl"/>
<map:serialize type="xml"/>
</map:match>
If this can be made to work, I do not have to repeat code for piplines P
and Q and all the other piplines which need slightly modiefied transforms
but for P and Q's portion itself.

Thanks. It does work.
For others, like me :) , here is simple example that I could make work:
<map:match pattern="**P1.xml">
<map:generate src="cocoon:/P.xml"/>
<map:serialize type="xml"/>
</map:match>
This example would call the P pipeline from P1 pipeline.
thanks

Use the "cocoon:" protocol. See the forrest sitemaps for loads of
exampls, e.g.
