ReceiveActor.ReceiveAsync(T) Method (Func(T, Task), Predicate(T))

ReceiveActorReceiveAsyncT Method (FuncT, Task, PredicateT)

Registers an asynchronous handler for incoming messages of the specified type T. If shouldHandle!=null then it must return true before a message is passed to handler.

Remarks

The actor will be suspended until the task returned by handler completes.

Remarks

This method may only be called when constructing the actor or from Become(Action) or BecomeStacked(Action).

Remarks

Note that handlers registered prior to this may have handled the message already. In that case, this handler will not be invoked.
