Each binding is declared in the context of a +module which is used to organize and refer to collections of bindings +at a time. Modules may be function pointers, or classes providing a +certain operator(). Groups of modules may be used together, to avoid +duplicate bindings. + +At runtime, one collects desired modules into a modules object, which +produces injectors. One can then ask an injector to provide a value +(instance) of a desired type (again supplied as a template parameter.) +When providing a value, implicit transitive dependencies are provided +as well. All values are exchanged with shared pointers +((std|std::tr1|boost)::shared_ptrs are supported) and the injector +takes care of disposing the value when the smart pointer deletes +itself. + +Requesting the injector for an unbound type results in a runtime +exception. No RTTI is used (but we use a portable, homebrew version +of same.) |
