Re: Getting list of Pages containing a specific annotation

[Howard Lewis Ship <hl...@gmail.com>]

Part of Tapestry's goals it to support very large applications with,
potentially, hundreds or even thousands of individual pages. To
support that goal, Tapestry is very lazy and does not attempt to load
pages (or transform their classes) until needed.

However, you can get a list of page names as suggested below and you
can get the non-enhanced class via the standard means, and use that to
check to annotations. It won't be as seamless if a class is added or
changed (or has annotations removed) but may get the job done for you.

Another technique I use is to leverage sub-packages and associate
behavior with all pages in a sub-folder. In this way, you can make
assumptions about incoming requests or even pages without having the
load the class and access the annotations.  Without knowing more about
what you are trying to accomplish I can't really get more specific
than that.
