The supported languages are defined in treeprocessor.xconf or cocoon.xconf, and the interpreted sitemap is "only" a particular pipeline assembly language implemented using this framework, but we could implement others like Berin's proposal or Daniela Gehle's flowmap (go back to october 2001 in the archives to find them). Having this clear in mind, there's no problem to speak of "interpreted sitemap". >Moreover, I'd love to be able to decide what to use (interpreted or >compiled) from cocoon.xconf.... or, in case the treeprocessor ends up >faster all the time, simply blast the compiled version and get rid of >that stupid javac! > The Processor used by Cocoon is a regular component : just change the class of the <sitemap> in cocoon.xconf and you're done ! And if we decide to blast the compiled version, we just have to change the default class in cocoon.roles. But let's both live together until we're sure the interpreted version is bug-free. >What do you think? > Sounds good :) However, I'd like to propose some package renaming to better organize things (inspired by some off-list discussion with Vadim) : - org.apache.cocoon.components.treeprocessor : the TreeProcessor framework - org.apache.cocoon.sitemap : classes common to both implementations - org.apache.cocoon.sitemap.java : classes specific to the compiled version - org.apache.cocoon.sitemap.tree : classes specific to the tree-based version Vadim proposed to insert "processor" before sitemap (i.e. "org.apache.cocoon.processor.sitemap") to outline the fact that sitemap is only one implementations of Processor among others, but I don't think such a depth is necessary unless we think to have more than a dozen different languages ;) And also, we should start discussing the integration of schecoon and interpreted sitemap, and more generally about Processor implementations that coexist in the system. I was thinking about some ProcessorManager or ProcessorSelector that any xxmap ('xx' = 'flow', 'site' or something else) could query to get others xxmaps (e.g. a sitemap calling a flowmap). I don't have clear thoughts about that, but it seems to me it should be able to discriminate Processor instances by the language (xxmap), the source file that defines it and the mount path (since a subsitemap behaviour depends on its parents). Thoughts ?
