Subject [VOTE] new switch-style selector
Date Mon, 15 Apr 2002 21:16:58 GMT
Hi team,

Marcus Crafter proposed a while ago a new style of Selector that would 
allow to factorize some common computation for all <map:when> cases 
instead of starting from scratch a each case as it is today. This is 
especially useful when the data that has to be tested is costly to 
obtain compared to the time of the actual test (e.g. select on a user 
role that is fetched in a database).

All this is decribed in and

Marcus originally called it "ContextualizableSelector", but this seemed 
inappropriate since there are already many Context objects around in 
Cocoon. So a better name came which was "SwitchStyleSelector" for its 
analogy with the switch construct in Java, whereas the current Selector 
is more analogous to if/else-if constructs.

So there are two questions :

- do you want this new style of selector ?

- do you have a better name than "SwitchStyleSelector" ?
I personally don't have ;)
