Method Overriding and Optional Parameters

Okay, as there’s general interest, here’s a quick version: Console.WriteLine(one) This will use the WriteLine(object) overload, which will in turn execute the object.ToString() virtual method, overridden in One – hence the output of ToString override Console.WriteLine(one.ToString()) This will look at One and see which methods have newly declared methods – discounting overrides.

Java doesn’t let you make the access modifier more restrictive, because that would violate the rule that a subclass instance should be useable in place of a superclass instance. But when it comes to making the access less restrictive… well, perhaps the superclass was written by a different person, and they didn’t anticipate the way … Read more

Overriding ToString() of List

Perhaps a bit off-topic, but I use a ToDelimitedString extension method which works for any IEnumerable<T>. You can (optionally) specify the delimiter to use and a delegate to perform a custom string conversion for each element: // if you’ve already overridden ToString in your MyClass object… Console.WriteLine(list.ToDelimitedString()); // if you don’t have a custom ToString … Read more

What’s the best way to override a user agent CSS stylesheet rule that gives unordered-lists a 1em margin?

If You Are Able to Edit the Offending Stylesheet If the user-agent stylesheet’s style is causing problems for the browser it’s supposed to fix, then you could try removing the offending style and testing that to ensure it doesn’t have any unexpected adverse effects elsewhere.

Override WooCommerce Frontend Javascript

I had the same problem except with add-to-cart.js. Simple solution is to DEQUEUE the woocommerce script and ENQUEUE your replacement. In my case I added the following to my functions.php: wp_dequeue_script(‘wc-add-to-cart’); wp_enqueue_script( ‘wc-add-to-cart’, get_bloginfo( ‘stylesheet_directory’ ). ‘/js/add-to-cart-multi.js’ , array( ‘jquery’ ), false, true ); You would want to DEQUEUE the ‘wc-add-to-cart-variation’ script. I don’t think … Read more
