Eclipse 3.5.2 (and possibly earlier versions) already provides this feature. If you right-click within the editor, you’ll find it under Source -> Generate toString()… To answer your question about whether it’s a bad practice to autogenerate toString(), my opinion is that it is not. If the generated code is very similar to the code you … Read more
the array.join function takes an optional delimiter parameter which will seperate the elements by the delimiter. A simple example: var showtimes = [“1pm”, “2pm”, “3pm”]; var showtimesAsString = showtimes.join(‘, ‘); // gives “1pm, 2pm, 3pm”
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
Use the “R” numeric format string: double d = 0.00034101243963859839; string s = d.ToString(“R”); //… double d2 = double.Parse(s); if(d == d2) { //– Success } The R stands for “round-trip”. From the linked document: This format is supported only for the Single and Double types. The round-trip specifier guarantees that a numeric value converted … Read more
I would personally avoid using BigInteger to convert binary data to text. That’s not really what it’s there for, even if it can be used for that. There’s loads of code available to convert a byte[] to its hex representation – e.g. using Apache Commons Codec or a simple single method: private static final char[] … Read more
Use this if the session variable emp_num will store a string: if (!string.IsNullOrEmpty(Session[“emp_num”] as string)) { //The code } If it doesn’t store a string, but some other type, you should just check for null before accessing the value, as in your second example.
In Lua 5.2 or earlier, both tostring(10) and tostring(10.0) result as the string “10”. In Lua 5.3, this has changed: print(tostring(10)) — “10” print(tostring(10.0)) — “10.0” That’s because Lua 5.3 introduced the integer subtype. From Changes in the Language: The conversion of a float to a string now adds a .0 suffix to the result … Read more
Updated to include caveats in the comments below from CMS, Tim Down, MooGoo: The closest thing available to what you’re after is calling .toString() on a function to get the full function text, like this: function derp() { a(); b(); c(); } alert(derp.toString()); //”function derp() { a(); b(); c(); }” You can give it a … Read more
So, how to get the string of the html of a Range or DocFrag? Contrary to the other responses, it is possible to directly turn a DocumentFragment object into a DOMString using the XMLSerializer.prototype.serializeToString method described at https://w3c.github.io/DOM-Parsing/#the-xmlserializer-interface. To get the DOMString of a Range object, simply convert it to a DocumentFragment using either of … Read more
It has some use for debugging, since it lets you see the code of the function. You can check if a function has been overwritten, and if a variable points to the right function. It has some uses for obfuscated javascript code. If you want to do hardcore obfuscation in javascript, you can transform your … Read more
