====== Usage ======
|
|
disp_t: your Dispatchable base class
|
|
implt_t: your implementation class
|
|
|
|
ServiceFactoryT<disp_t, impl_t> myFactory;
|
|
impl_t myImplementation;
|
|
|
|
//....
|
|
|
|
//during service registration
|
|
myFactory.Register(WASABI_API_SVC);
|
|
|
|
//during service deregistration
|
|
myFactory.Deregister(WASABI_API_SVC);
|
|
|
|
==== Class requirements ====
|
|
your base or implementation class requires the following three static methods
|
|
static FOURCC getServiceType(); // return your type (e.g. WaSvc::UNIQUE)... might already be defined in the dispatchable base class
|
|
static const char *getServiceName(); // return your service name
|
|
static GUID getServiceGuid(); // return your service GUID
|
|
must implementation a constructor that requires no parameters
|
