Actually, Mikhail’s answer is not quite right. In the case that someFunction is a function that returns a value even if none is requested, which is how a function indicates that the value should be assigned to ans, Mikhail’s wrapper will fail. For example, if someFunction were replaced with sin and you compared running wrapper … Read more
No practical difference. Either L or l can be used, both indicate a long primitive. Also, either can be autoboxed to the corresponding Long wrapper type. However, it is worth noting that JLS-3.10.1 – Integer Literals says (in part) An integer literal is of type long if it is suffixed with an ASCII letter L … Read more

A wrapper is a bit of code that sits on top of other code to recycle it’s functionality but with a different interface. This usually implies an interface written in the same language. It should also be noted that sometimes people will say wrapper when what they technically mean is a binding (myself included). Pros: … Read more
Apache Commons Lang has a utility method to do this (ClassUtils.primitiveToWrapper()), which will be just as ugly under the covers, but at least you can pretend it’s nice.
Personally instead of polluting builtin objects I would go with a decorator technique: var makeSafe = function(fn){ return function(){ try{ return fn.apply(this, arguments); }catch(ex){ ErrorHandler.Exception(ex); } }; }; You can use it like that: function fnOriginal(a){ console.log(1/a); }; var fn2 = makeSafe(fnOriginal); fn2(1); fn2(0); fn2(“abracadabra!”); var obj = { method1: function(x){ /* do something */ … Read more
defaultdict docs say for default_factory: If the default_factory attribute is None, this raises a KeyError exception with the key as argument. What if you just set your defaultdict’s default_factory to None? E.g., >>> d = defaultdict(int) >>> d[‘a’] += 1 >>> d defaultdict(<type ‘int’>, {‘a’: 1}) >>> d.default_factory = None >>> d[‘b’] += 2 Traceback … Read more
In .NET, you can use the InternalsVisibleToAttribute in your class library to make your internal types visible to your unit test project. That way, you can keep your class internal and still use it from other assemblies that you give access. You use it like this: [assembly:InternalsVisibleTo(“NameOfYourUnitTestProject”)]
See the command search sequence on Microsoft Docs The PATH and PATHEXT environmental variables each provide an element of the search sequence: PATH is the ordered list of directories “where” to look, and PATHEXT is the ordered list of file extensions (“what“) to look for (in case the extension isn’t explicitly provided on the command … Read more
