j2v8: creating new instance of binded object

Our teams is currently under consideration of which JavaScript Engine Bridge to use. We are choosing between LiquidCore and J2V8. My question is concerning j2v8. Supposedly, I have to create several instances of some java class in JavaScript, how can one achieve this in j2v8 using standard instantiation annotation (new ClassName())? In liquidcore you can bind some class, that extends JSFuction, with super constructor:

JSFunction(JSContext ctx, final String methodName, final Class<?extends JSObject> instanceClass)

and register property with desired class name like this:

jsBaseContext.getJsContext().property("WebSocket", this);

and then on calling:

var x = new WebSocket();

java method methodName will fire, where we'll get new instanceClass as JSValue object as parameter, already binded and ready to use in javascript.

Solution

  • Since no one is going to discuss this topic, i'll answer myself. This feature is not currently considered to be added in official J2V8 release, however there is a branch on Mizumi's pull request. So, have a look, if you've faced similar issues.
