http://www.codeproject.com/KB/mcpp/quickcppcli.aspx#A8 This is general direction. You need to create C++/CLI Class Library project, add .NET class to it (StudentWrapper in this sample), create unmanaged class instance as managed class member, and wrap every unmanaged class function. Unmanaged library is added to C++/CLI project using linker dependencies list, and not as reference. In the Project – … Read more
The problem with wrappers is that they will obfuscate file name and line number of the source of the log message. Simple IE7 and below shim that preserves Line Numbering for other browsers: /* console shim*/ (function () { var f = function () {}; if (!window.console) { window.console = { log:f, info:f, warn:f, debug:f, … Read more
A “wrapper class” is a de facto term meaning a class that “wraps around” a resource; i.e, that manages the resource. When people write a wrapper, then, they are doing something like this: class int_ptr_wrapper { public: int_ptr_wrapper(int value = 0) : mInt(new int(value)) {} // note! needs copy-constructor and copy-assignment operator! ~int_ptr_wrapper() { delete … Read more
The answer, surprisingly, is zero. All the Integers from -128 to +127 are pre-computed by the JVM. Your code creates references to these existing objects.
The key to the answer is called object interning. Java interns small numbers (less than 128), so all instances of Integer(n) with n in the interned range are the same. Numbers greater than or equal to 128 are not interned, hence Integer(1000) objects are not equal to each other.
There are lots of good answers here, but I didn’t see any that address the question of whether you can accomplish this via decorators. The short answer is “no,” at least not without structural changes to your code. Decorators operate at the function level, not on individual statements. Therefore, in order to use decorators, you … 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”)]
The cleanest way I know of for doing this is the following: import functools def decorator(original_function=None, optional_argument1=None, optional_argument2=None, …): def _decorate(function): @functools.wraps(function) def wrapped_function(*args, **kwargs): … return wrapped_function if original_function: return _decorate(original_function) return _decorate Explanation When the decorator is called with no optional arguments like this: @decorator def function … The function is passed as … Read more
You can do all kinds of fun stuff with javascript, including redefining functions: let a = function() { return 1; } console.log(a()); // 1 // keep a reference let old = a; // redefine a = function() { // call the original function with any arguments specified, storing the result const originalResult = old.apply(old, arguments); … Read more
Vue 3 Same as the Vue 2.6 example below except: $listeners has been merged into $attrs so v-on=”$listeners” is no longer necessary. See the migration guide. $scopedSlots is now just $slots. See migration guide. Vue 2.6 (v-slot syntax) All ordinary slots will be added to scoped slots, so you only need to do this: <wrapper> … Read more
