wow or normal?!

[Marc Logemann <de...@logemann.info>]

Hi,

i am quite astonished that velocity is able to determine
the Type of a collection at runtime. When doing #foreach
on a collection type, i dont need to cast anything and can
just start of by doing $collection.specificTypeAttribute.

Can somebody explain me whats going on inside velocity? This
really surprised me and i must say: well done.

Thx for infos

Normal!

Take a look at the code - basically, it just looks to see what the 2nd arg
to #foreach() is (Collection, [], iterator, enumerator) and just deals with
it accordingly.

This allows you to keep the implementation of your data model free from how
the designer uses it (for most cases...)
