createSync2<TResult> method

RxCommand<Null, TResult> createSync2 <TResult>(Func<TResult> func, { Observable<bool> canExecute, bool emitInitialCommandResult: false })

Creates a RxCommand for a synchronous handler function with no 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 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<Null, TResult> createSync2<TResult>(Func<TResult> func,{Observable<bool> canExecute, bool emitInitialCommandResult = false})
{
    return new RxCommandSync<Null,TResult>((_) => func(),canExecute, emitInitialCommandResult);
}
