> I would like to introduce a new feature to Sling Models named Exporters.
> Exporters allow for a model class to be exported into a specific Java object type in a automated fashion. The simplest example is to support String serialization, although different Exporters may support whatever target classes they see fit.
> Exporters are implemented through an SPI. This initial contribution includes an exporter using the Jackson library which supports both {{String}} and {{Map}} exports.
> Interfacing with the registered Exporters is done through three new methods on the {{ModelFactory}} interface:
> * {{exportMode}}
> * {{exportModelForResource}}
> * {{exportModelForRequest}}
> In addition, using these functionality, model objects can have automatically-registered servlets which export the model (from either the request or the request's resource) as a {{String}} and then serve that {{String}} to the client.
> Registering these servlets is done through a new annotation named {{@Exporter}}
> For example, you might add this annotation to a Model class
> {{@Exporter(name = 'jackson', extension = 'json')}}
> This will register a servlet for the model's resource type with the extension `json` and a selector of `model` (by default, the {{@Exporter}} annotation can also define a different selector).
