I'd like to wire a ReactiveCommand up to a ConnectableObservable, since the observable should be connectable by multiple subscribers.
The problem is that ReactiveCommand will only call the Subscribe method on the ConnectableObservable, rather than the Connect method as I would like.
The code below demonstrates what I'm trying to achieve. Notice the StartOrConnectService method that is called by service code.
public class Foo
{
public IConnectableObservable<string> Connection { get; }
public Foo(BarService barService)
{
Connection = Observable.Create<string>(observer =>
{
disp = barService.BarStream().Subscribe(
bar => {
Console.WriteLine($"{bar}");
observable.onNext("Connected");
},
ex => observable.onNext("Errored"),
() => observable.onNext("Disconnected")
);
return disp;
}).Publish();
}
// This method is called by service code.
public IDisposable StartOrConnectService()
{
// bunch of other stuff going on here, but essentially calling connect
return Connection.Connect();
}
}
public sealed class FooViewModel : ReactiveObject
{
public ReactiveCommand<Unit, string> ConnectCommand { get; }
public FooViewModel(Foo foo)
{
ConnectCommand = ReactiveCommand
.CreateFromObservable(() => foo.Connection);
}
}
Is there some way of adapting or wrapping a ConnectableObservable to a regular Observable so the ConnectableObservable.Connect method is called when the ReactiveCommand executes?
