Content delivery within an application

摘要

A view component of an application requests content from a model component of the application, where the request for content includes a request for data. The model component determines whether the requested data is available. If the requested data is available, the model component delivers the requested content and the requested data. If the requested data is not available, the model component first delivers the requested content and a data placeholder, and after the model component retrieves the data, the model component delivers the requested data to replace the data placeholder.
