Hi guys,
is there any way to use shared members without casting them? Fox example:
class Example {
private shared HashSet!(string) ex;
...
this() {
ex = cast(shared) new HashSet!(string)();
}
void write() {
foreach (ref c; cast(HashSet!(string)) ex) {
std.stdio.writeln(c);
}
}
}
Without casting, I always get some errors. My classes contains many
different
collections and values, so I've many casts which makes the code at some
points
a bit unclear. Is there any way to prevent the casting from/to shared
objects?
The objects have to implement shared methods directly. From your sample
code, I assume you are using dcollections.
I have not yet thought about how to tackle shared versions of containers.
Certainly, your code is not a good way to do it, since you are not doing
any synchronization.
The issue is, if a container is shared, you may only call shared methods
on it. I have no shared methods in dcollections, because they would be
simple wrappers for synchronizing the methods on the container. I would
like to find an automatic way to do this rather than use boilerplate
everywhere.
I also would like to investigate shared-aware containers that are safer to
use (possibly lock-free) than simply synchronizing all methods.
