createAsync3<TParam, TResult> method

RxCommand<TParam, TResult> createAsync3 <TParam, TResult>(AsyncFunc1<TParam, TResult> func, { Observable<bool> canExecute, bool emitInitialCommandResult: false, bool emitLastResult: false })

Creates a RxCommand for an asynchronous handler function with parameter that returns a value func: handler function canExecute : observable that can bve used to enable/diable 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 emitLastResult will include the value of the last successful execution in all CommandResult events unless there is no new result. 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, isExceuting==false pass emitInitialCommandResult=true.

Implementation

static RxCommand<TParam, TResult> createAsync3<TParam, TResult>(AsyncFunc1<TParam,TResult> func, {Observable<bool> canExecute, bool emitInitialCommandResult = false, bool emitLastResult=false})
{
    return new RxCommandAsync<TParam,TResult>((x) async => func(x),canExecute, emitInitialCommandResult,emitLastResult);
}
