com.linkedin.r2.message.rest.RestResponse
An object that contains details of a REST response.
Instances of RestResponse are immutable and thread-safe. New instances can be created using the {@link RestResponseBuilder}. An existing RestResponse can be used as a prototype for building a new RestResponse using the {@link #builder()} method. @author Chris Pettitt @version $Revision$
