Re: [patterns-discussion] Using Design Patterns without dynamic memory allocation

[Linda Rising]

You might find that just a handful of patterns can help you make significant improvements. A little information hiding here and a single, focussed design decision there.... Good luck! Linda Ralph Malph wrote: Thanks, Linda. That describes me exactly. I am working on a quite large embedded system that was written by "senior" engineers at a research facility with minimal if any training in modern software design techniques. The software is a mess, and I'm starting to look at patterns as a way to restructure it. The entire code base is written in C++ without dynamic memory allocation, and from my initial pass through parts of the GoF book, it looked like dynamic memory allocation would be a requirement for using design patterns. I'll take a closer look at them.

Some of those folks (who got the wrong idea) were in the development community I knew best -- large, safety-critical, real-time, embedded, systems. Those folks took one look at the GoF book and said, "Nothing in here for me!" and dismissed it out of hand. This was unfortunate. A design pattern has nothing to do with dynamic memory allocation. Sure, many examples or implementations show this, but, for example, you can use a Mediator in FORTRAN!! Don't give up on design patterns, Ralph! They're an attempt on the part of well-meaning designers to share the best they know. We can all benefit regardless of our particular environment. Linda Ralph Malph wrote: 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.
