Suppose that I receive a message, but instead of defining a
function inside the receive() block, I want to call a member of a
class instance. (This is useful to me for several reasons). Right
now my code looks like:
class Handler {
auto handle() {
return (string msg) {
writeln("received: ", msg, " count: ", i);
}; // this ';' ends the return statement
} // handle()
private:
i;
}
//somewhere inside main
auto handler = new Handler;
receiveTimeout( dur!"seconds"(1),
handler.handle
);
It works, but I must say I'm not even sure about what the hell I
am doing :D
If I got it correctly, I'm calling a function that returns a
delegate, which is used by the receiveTimeout() somehow to
dispatch the message (and everything is in some way decided at
compile time, I believe).
Does this ugly piece of code make any sense? Should I rework it?
