General talk about software patterns

[Holger Mügge <muegge AT iai.uni-bonn.de>]

Hi,

in the builder pattern typically the client directly fetches the built
product from the concrete builder calling the getResult() method (cf.
the seqence diagram I attached).

I wonder whether it would be better to let the director do this and
return the product in its contruction method. I see two advantages: 1.
the client does not have to know the concrete builder, 2. no
synchronization is needed in case the client and the director work in
parallel. Do I overlook something?

Thanks for advices,

Holger
