Hi Upayavira,
I missed your email somehow. Yep this one is used by the Lucene block.
It depends on a link view being available in the sitemap and crawls
cocoon over http. I had started implementing a publisher block in the
same vein as the Lucene block because I couldn't really see how to
achieve it the way we discussed a few weeks back, i.e. within the VM,
without first changing a lot internals. This patch is a step toward
that.
I haven't had time to continue with it unfortunately. Also, the boss
decided on our current publisher - that depends on incompatible usage of
cocoon internals - as we already put some effort into that. But I can't
see how I could change the code easily so that it integrates with the
current cocoon. I hope to continue with the cocoon publisher block in
the fall. Sorry, I should have let you know what was happening before
especially because you showed so much interest before.
In a nutshell the idea I had for the Publisher interface:
interface Publisher extends SingleThreaded {
/**
* parametrize the publisher with the location where
* from where to start publishing and the depth to publish
* to.
*/
void publish(URL url, int depth);
/**
* after parametrizing the publisher as above, obtain a
* an iterator of Publications on the publish path.
*/
Iterator iterator();
}
This interface is inspired by the CocoonCrawler interface that I found
very elegantly allows client code control over it through the iterator.
The Iterator could hold Publication objects:
Interface Publication {
Long lastModifiedDate();
Long lastPublicationDate();
void publish();
}
The publisher could eventually also have an implementation that
processes directly on the Cocoon object instead of over http. That were
my initial ideas about that I haven't been able to continue yet. Off
course it could be implemented in a hundred other ways equally elegant
:)
Regards,
Unico
