A template is a blueprint for JavaScript functions and objects. You can use a template to wrap C++ functions and data structures within JavaScript objects. V8 has two types of templates: Function Templates and Object Templates.
- Function Template is the blueprint for a single function. You create a JavaScript instance of template by calling the template’s GetFunction method from within the context in which you wish to instantiate the JavaScript function. You can also associate a C++ callback with a function template which is called when the JavaScript function instance is invoked.
- Object Template is used to configure objects created with function template as their constructor. You can associate two types of C++ callbacks with object templates: accessor callback and interceptor callback. Accessor callback is invoked when a specific object property is accessed by a script. Interceptor callback is invoked when any object property is accessed by a script. In a nutshell, you can wrap C++ objects\structures within JavaScript objects.
