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.
Regards,
Christophe Addinquy

Objet: [patterns-discussion] Using Design Patterns without dynamic
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!
