anonymous-class

I can define an anonymous class within an anonymous module: c = nil m = Module.new do c = Class.new end m #=> #<Module:0x007fad3a055660> c #=> #<Class:0x007fad3a0555e8> Is the above equivalent to: m = Module.new c = Class.new In other words: does the concept of "nesting" actually apply to anonymous modules? It is not about being anonymous. Assigning a dynamically created class to a constant makes it named: Foo = Class.new # => Foo foo = Class.new # => #<Class:0x007fe5dd45d650> Yet it still doesn't nest further: module Bar Baz = Module.new do p Module.nesting # => [Bar] end end Or even about

I am using the following class to mimic anonymous objects in PHP: class AnonymousObject { protected $methods = array(); public function __construct(array $options) { $this->methods = $options; } public function __call($name, $arguments) { $callable = null; if (array_key_exists($name, $this->methods)) $callable = $this->methods[$name]; elseif(isset($this->$name)) $callable = $this->$name; if (!is_callable($callable)) throw new BadMethodCallException("Method {$name} does not exist"); return call_user_func_array($callable, $arguments); } } ( https://gist.github.com/Mihailoff/3700483 ) Now, as

This is a question about Java code such as: List<String> list = new ArrayList<String>() {{add("hello"); add("goodbye");}} where the programmer has extended ArrayList anonymously just for the sake of shoving in an instance initialization block. The question is: if the sole intention of the programmer is merely to achieve the same as: List<String> list = new ArrayList<String>(); list.add("hello"); list.add("goodbye"); then what are the unintended consequences of doing it the first way? The danger of doing that sort of code (in the general case) is that you might break equals() methods. That's

I thought I'd be able to make an ordered map type by using anonymous fields: type customMap struct{ map[string]string ordered []string } where I could reference the map with customMapInstance["key"] and iterate over ordered . Alas, it appears arrays and maps are not valid anonymous fields. I suspect there's a good reason... From the spec: An embedded type must be specified as a type name T or as a pointer to a non-interface type name *T, and T itself may not be a pointer type. You see that it mentions a "type name". Named types are specified by a (possibly qualified) type name; unnamed types

I'm trying to use an event dispatcher to allow a model to notify subscribed listeners when it changes. the event dispatcher receives a handler class and a method name to call during dispatch. the presenter subscribes to the model changes and provide a Handler implementation to be called on changes. Here's the code (I'm sorry it's a bit long). EventDispacther: package utils; public class EventDispatcher<T> { List<T> listeners; private String methodName; public EventDispatcher(String methodName) { listeners = new ArrayList<T>(); this.methodName = methodName; } public void add(T listener) {

Is there any reason to why you cant serialize anonymous classes to Json? Example: public class AnonymousTest { private Gson gson = new Gson(); public void goWild() { this.callBack(new Result() { public void loginResult(Result loginAttempt) { // Output null System.out.println(this.gson.toJson(result)); } }); } public void callBack(Result result) { // Output null System.out.println(this.gson.toJson(result)); result.loginResult(result); } public static void main(String[] args) { new AnonymousTest().goWild(); } } Just getting started with it :) It is explained in the user guide: https://sites
