Hi Everybody,
Please have a look at the appended sucky code.
Obv. the createHandlerCode function is a pain in the back side for
extending this system; I want multiple different partially specialised
implementations.
So whats the syntax for doing partial specialisation?
Damed if I can work it out.
==================
enum EHandlerType {
eMsgRangeHdlr,
eMsgHdlr,
eCmdIdHdlr
}
template createHandlerCode(T ...) {
string format() {
static if(T[0]._type == EHandlerType.eMsgRangeHdlr)
return createMessageRangeHandler!(T).format();
else static if(T[0]._type == EHandlerType.eMsgHdlr)
return createMessageHandler!(T).format();
else static if(T[0]._type == EHandlerType.eCmdIdHdlr)
return createCommandIdHandler!(T).format();
else
static assert(false, "handler type not handled");
}
}
struct msgRangeHdlr(uint msgIdFirst, uint msgIdLast, string
responseMethod) {
invariant EHandlerType _type = EHandlerType.eMsgRangeHdlr;
invariant string _msgIdFirst =
std.metastrings.ToString!(msgIdFirst);
invariant string _msgIdLast =
std.metastrings.ToString!(msgIdLast);
invariant string _responseMethod = responseMethod;
}
struct msgHdlr(uint msgId, string responseMethod) {
invariant EHandlerType _type = EHandlerType.eMsgHdlr;
invariant string _msgId = std.metastrings.ToString!(msgId);
invariant string _responseMethod = responseMethod;
}
struct cmdIdHdlr(uint cmdId, string responseMethod) {
invariant EHandlerType _type = EHandlerType.eCmdIdHdlr;
invariant string _cmdId = std.metastrings.ToString!(cmdId);
invariant string _responseMethod = responseMethod;
}
