-// This class provides an easy way to convert from a Script-exposed
-// class (i.e. a class that has a toV8() overload) that uses Promises
-// to a WebKit API class that uses WebCallbacks. You can define
-// separate Success and Error classes, but this example just uses one
-// object for both.
-//
-// To use:
-//
-// class MyClass ... {
-// typedef blink::WebMyClass WebType;
-// static PassRefPtr<MyClass> from(ScriptPromiseResolver* resolver,
-// blink::WebMyClass* webInstance) {
-// // convert/create as appropriate, but often it's just:
-// return MyClass::create(adoptPtr(webInstance));
-//
-// // Since promise resolving is done as an async task, it's not
-// // guaranteed that the script context has seen the promise resolve
-// // immediately after calling onSuccess/onError. You can use the
-// // ScriptPromise from the resolver to schedule a task that executes
-// // after resolving:
-// ScriptState::Scope scope(resolver->scriptState());
-// resolver->promise().then(...);
-// }
-//
-// Now when calling into a WebKit API that requires a WebCallbacks<blink::WebMyClass, blink::WebMyClass>*:
-//
-// // call signature: callSomeMethod(WebCallbacks<MyClass, MyClass>* callbacks)
-// webObject->callSomeMethod(new CallbackPromiseAdapter<MyClass, MyClass>(resolver, scriptExecutionContext));
-//
-// Note that this class does not manage its own lifetime. In this
-// example that ownership of the WebCallbacks instance is being passed
-// in and it is up to the callee to free the WebCallbacks instace.
