Subject [jira] Updated: (COCOON3-8) Add a Digester processor Finisher for the Pipeline
Date Fri, 31 Oct 2008 19:23:44 GMT


Simone Tripodi updated COCOON3-8:

    Attachment: DigesterFinisherWithBetwixtTest.patch

The second attached patch shows how the DigesterFinisher works also with the Betwixt's BeanReader,
being a Digester extension.
Basically contains the same code of the first patch, the test case has changed.

> The Pipeline is useful not only to stream XML to an OutputStream, but also to implement
efficient XML processors; an hypothetical scenario can be an XML -> DB pipeline, with intermediary
transformations and validation.
> The Apache community owns an extraordinary XML Processor called Digester - informations
can be found on
> The Digester itself is an org.xml.sax.helpers.DefaultHandler extension, so it can be
easily integrated in the pipeline's flow.
> It have to be a finisher, and not an intermediary component, because the Digester is
focused on XML -> Java Objects, so it doesn't make sense transforming XML to POJOs and
 than XML again
