Outputable (Sakai Entity Broker API 22.3 API)

All Superinterfaces:

EntityProvider, Formats

All Known Subinterfaces:

OutputFormattable, OutputSerializable, RESTful
```
public interface Outputable
extends EntityProvider, Formats
```
These entities can be returned as certain output formats which are handled automatically
If you want to define the data that is returned instead of using the internal methods then use OutputFormattable

NOTE: By default all entity view requests go through to the available access providers: EntityViewAccessProvider or HttpServletAccessProvider NOTE: there is no internal handling of HTML, it will always redirect to the the available access provider if there is one (if there is not one then the entity will be toStringed)
