hello all: I have a fairly large code base that has a lot of modules and systems. The problem is that I have a main "engine" object that holds pointers to a lot of created modules and components. I'm trying to find a more dynamic way to do this, and I thought boost might be able to help. As a result, I have a couple of questions. First, I do a lot of manual adding of features. For example, when I add a new command I have to add a engine->commands.AddCommand(new CMDFoo()); in an initialization method. Does boost provide some sort of mechenism for dynamically handling this? I also plan on splitting up the main "engine" object and setting up the external modules as singletons. They act alone, but again I'd like to dynamically initialize these. Is there a way on entry to dynamically call specific singleton initialization methods, then at exit call their release methods? I'd like to be able to set some sort of trait on these objects at compile-time that the runtime can use, or somehow generate the calls at compile-time. Thanks in advance for any info, -- Take care, Ty http://tds-solutions.net He that will not reason is a bigot; he that cannot reason is a fool; he that dares not reason is a slave.
