proxy-classes

I created a Proxy object with an "apply" trap: var target = {}, handler = { apply: () => 42 } proxy = new Proxy(target, handler); Therefore, the Proxy object should be callable. However, it doesn't work: proxy(); // TypeError: proxy is not a function Why? According to the definition of the [[Call]] internal method of Proxy objects it should work: Let trap be GetMethod ( handler , "apply" ). Return Call ( trap , handler , « target , thisArgument , CreateArrayFromList ( argumentsList )»). However, there is a problem: not all Proxy objects have the [[Call]] method: A Proxy exotic object only has

I have a webservice that I'm calling from a windows forms application (both .NET, both in the same solution), and I'd like my webservice to return a custom object from elsewhere in the project - it's a common object that they both share a reference to, as it's in the third project in my solution. When I call the webservice, it returns a "Person" object, but it's in the namespace of the webservice, and it's created from a proxy class that the webservice itself generated. As such, I can't manipulate it and return it to my program, which is expecting a "Person" object based on the shared copy of

I have some web methods that return my objects back as serialized XML. It is only serializing the NHibernate-mapped properties of the object... anyone have some insight? It seems to be that the web methods are actually serializing the NHibernate proxies instead of my classes. I've tried using [XMLInclude] and [XMLElement], but the properties are still not serializing. I have a really horrible hackish way of getting around this, but I wondered if there was a better way! Something like this: <?xml version="1.0" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="StoryManager"

I know this is probably painfully basic, but i am having a tough time wrapping my head around it. class Main { constructor() { requestAnimationFrame(this.update); //fine } update(): void { requestAnimationFrame(this.update); //error, because this is window } } It appears to be the case that I need a proxy, so lets say using Jquery class Main { constructor() { this.updateProxy = $.proxy(this.update, this); requestAnimationFrame(this.updateProxy); //fine } updateProxy: () => void update(): void { requestAnimationFrame(this.updateProxy); //fine } } But coming from an Actionscript 3 background, I

I would like to test if a JavaScript object is a Proxy . The trivial approach if (obj instanceof Proxy) ... doesn't work here, nor does traversing the prototype chain for Proxy.prototype , since all relevant operations are effectively backed by the underlying target. Is it possible to test if an arbitrary object is a Proxy? In my current project I also needed a way of defining if something was already a Proxy, mainly because I didn't want to start a proxy on a proxy. For this I simply added a getter to my handler, which would return true if the requested variable was "__Proxy": function
