Hi Kencho, Thanks for your reply. I am still learning the patterns, so I'll take a close look at the patterns you mentioned.
The problem is not that we have limited memory, but that we are not allowed to use dynamically allocated memory (no heap). I have envisioned the use of statically created objects in the place of dynamically created ones, and I just wanted to make sure that it made sense to do it that way in light of how the patterns are implemented. It seems like I see a lot of dynamic memory being allocated in the examples of the books I have read (GoF, Head First DP), but I now know that it is not usually a requirement but rather a convenience or merely the "standard". There doesn't seem to be much consideration for real-time systems in the books I read, and most of them use Java, which is right out for me. Thanks again, Andre --- Kencho san <[EMAIL PROTECTED]> wrote: > I'm not sure what's your problem, but I'll try to > answer. > > Almost any non-creational pattern can be aplied > without dynamic memory > allocation, for instance the template method, state > pattern, facade, > adapter... all of them can make use of > composition-like relationships rather > than reference relationships (note that reference > doesn't mean dynamic > memory allocation, but usually involves it) > > If your problem is about design patterns helping you > avoid dynamic memory > allocation (you have space for a maximum amount of > objects and can't waste > time or memory to store more...), I would suggest > taking a look to the > Object Pool pattern, which is a very clever way to > reuse already existing > objects instead of creating and destroying them > constantly > > Hope that helps > > >Hello all, looking at archives I'm not sure how > >"alive" this list is, but someone out there might > be > >listening. > > > >I'm interested in people's opinions as to whether > >design patterns would be useful if you could not > >dynamically allocate memory. > > > >I am new to patterns and find them quite > interesting. > >I am considering putting in some effort to > comprehend > >them, but my projects at work include embedded > >safety-critical real-time systems, and one of the > >things that we do not use is dynamic memory > >allocation. > > > >If anyone has an opinion as to whether I should > delve > >into patterns for this type of software (i.e. you > have > >considered doing them and/or done them in similar > >systems before) I'd be interested to hear it. > > > >Thanks! > > > > > > > >__________________________________ > >Do you Yahoo!? > >Yahoo!
