General talk about software patterns

["Christophe Addinquy" <Christophe.Addinquy AT valtech.fr>]

Hi Ralph,
 
You've already received construtive answers, I think. I will try to add a 
little bit, if possible...
 
I will split my answer in 2 parts:
1) can we use DP without dynamic memory allocation ?
2) Is the pattern approach something useful in your case ?
 
1) obviously, DP isn't about dynamic memory allocation, but make an extensive 
use of this facility. For the patterns that use stateless objects (the 
strategy, for example), it should be quite straightforward to move to an 
implementation based on static shared object. For the other ones, it's 
probably more challenging. But, if you reach it, you have the meat for a good 
paper ;)
 
2) Don't forget that implementation, in the DP is just an example ! The 
important things, in the DP are:
  a) The DP is a solution to a problem in a given context
  b) The solution should be regarded as the "essence of the solution". The 
concrete solutions are possibles variations around this "essence".
 
Look also outside the GoF book, you may find things interesting for you. 
James Noble & Charles Weir have written "patterns for small memory software" 
which target embedded devices like PDA, cell phones, etc... You may find this 
material suitable for you.

memoryallocation
        
        

        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!
