createAsyncNoResult<TParam> static method
Creates a RxCommand for an asynchronous handler function with one parameter and no return type
action
: handler function
canExecute
: observable that can be used to enable/disable the command based on some other state change
if omitted the command can be executed always except it's already executing
isExecuting will issue a bool
value on each state change. Even if you
subscribe to a newly created command it will issue false
For the Observable<CommandResult>
that RxCommand implement this normally doesn't make sense
if you want to get an initial Result with data==null, error==null, isExecuting==false
pass
emitInitialCommandResult=true
.
By default the results Observable and the RxCommand itself behave like a PublishSubject. If you want that it acts like
a BehaviourSubject, meaning every listener gets the last received value, you can set emitsLastValueToNewSubscriptions = true
.
debugName
optional identifier that is included when you register a globalExceptionHandler
or a loggingHandler
