digitalmars.D - To auto or not to auto?
- Daniel Keep (22/22) May 05 2006 Hi all.
Hi all. I'm currently working on improving my cairo (a 2D drawing library, if you haven't heard of it) bindings for D with an OO layer, and I'm trying to decide if I should make all the resource classes auto. The thing is, cairo uses a reference counting system to manage the lifetime of objects. I imagine this is partially because on various systems, the number of, say, drawing contexts you can have at once is limited. Thus, you naturally want these objects freed as quickly as possible. So my first reaction was to make all the classes auto so that it's impossible (or at least very, very difficult) to leave stray objects lying around, waiting to be GCed. But this means that none of the objects can be stored in, say, member variables, or globals, etc. Considering that the library is for drawing 2D graphics (both in and out of GUI environments), is there any major drawback to using auto classes—enough to make them non-auto and risk leaking resources? My thanks to the many people on this NG who are *way* smarter than I am :) -- Daniel -- v1sw5+8Yhw5ln4+5pr6OFma8u6+7Lw4Tm6+7l6+7D a2Xs3MSr2e4/6+7t4TNSMb6HTOp5en5g6RAHCP http://hackerkey.com/
