12.15.1. About the Atom API and Provider
The RESTEasy Atom API and Provider is a simple object model that RESTEasy defines to represent Atom. The main classes for the API are in the
org.jboss.resteasy.plugins.providers.atom package. RESTEasy uses JAXB to marshal and unmarshal the API. The provider is JAXB based, and is not limited to sending atom objects using XML. All JAXB providers that RESTEasy has can be reused by the Atom API and provider, including JSON and fastinfoset. Refer to the javadocs for more information on the API.
