Generic callback interface used by RestTemplate's retrieval methods. Implementations of this interface perform the actual work of extracting data from a ClientHttpResponse, but don't need to worry about exception handling or closing resources.

Used internally by the RestTemplate, but also useful for application code. There is one available factory method, see RestTemplate#responseEntityExtractor(Type).
