Hi.,
I had same problem earlier..but after little bit of
"code" reading..this is what i come up with..
Ofcourse, this explanation is purely my understanding
and it may be true to core...
1. The "inherited", we are talking about really doesnt
exist. From the code perspective, the sub sitemaps are
independent of main sitemap.
2. If u look at some of the components of c2 (like
transformers) with perspective of pure objects living
in the environment pool to be accessed ans requested
to do some job, then all the sitemaps could use them
irrespective of the fact that they are defined in THAT
particular sitemap file or not. Defining them only
ensures that they WILL be created and made accessible.
3. On the other hand. Some of the components(from
sitemap file perspective) like matcher is not really
like the point2. The matcher functionality requires
code & logic to be embedded into generated sitemap
java file. Hence these type of "components" need to be
mentioned so that that the code generation framework
takes care of it.
This is what my understanding. Correct me if u have
any points towards this.
