arguments

问题 In ActionScript I can use ... in a function declaration so it accepts arbitrary arguments: function foo(... args):void { trace(args.length); } I can then call the function passing an array: foo.apply(this, argsArray); I'd like to call the function with arguments of unknown type and count. Is this possible in Haxe? 回答1: According to the Haxe documentation, you can use a Rest argument: If the final argument of a macro is of type Array<Expr> the macro accepts an arbitrary number of extra

问题 First, in case anyone wonders why we're invoking PowerShell in this way, I ran into this behavior with a more complex command we were building, but the behavior can be exhibited using a more simple example as shown below. In practice, we are running a command under 32-bit PowerShell as admin with additional variables rendered in the string (hence why I don't simply use single-quotes for the outer portion), but that doesn't seem to factor into the behavior below. When I invoke PowerShell

问题 I have an issue running a certain script in octave. This is the code that produces the error: #germanium T=410:20:600; x=linspace(400,410,100); y=linspace(10^9,10^9,100); k=8.5*10 .^(-5); Eg=0.59; Nc300=1.02*10^13; Nc=Nc300*((T/300).^(3/2)); n=Nc*(e.^(-Eg/(2*k*T))); plot(T,n,x,y,'m'); grid on xlabel('Temprature'); ylabel('Electron Density n'); title('Germanium n(T)'); As mentioned in the Title, the error that is produced is the following: error: ger5: operator /: nonconformant arguments (op1

问题 We have a websphere application server where multiple applications are deployed. All applications use a common property(Key) but have different Value. For example : spring.profiles.active=test in one application, spring.profiles.active=UAT in some other application. Is it possible to pass these different values to the applications during start-up in Websphere ? If we set these values in JVM options in the Generic JVM Arguments text box then it will become same for all the applications which

问题 I have a functioning event listener and delegate handler like this: def eHandler(source, sym, bid, ask) : qstr = '{} {:.5f} {:.5f}'.format(sym,bid,ask) print(qstr) ... mtc.QuoteUpdated += eHandler However, I suspect the event also provide an object (?) with keywords which I don't know what they are. I have tried to do something like the following, but it doesn't work. def eHandler2(src, *args, **kwargs): k = args print('{} {:.5f} {:.5f}'.format(k.Instrument, k.Bid, k.Ask)) print('src: {}
