Interface representing a V8 context handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the ICefV8context.GetTaskRunner() function. </p>
