Interface ResponseListener

public interface ResponseListener
Listener to be provided when calling async performRequest methods provided by RestClient. Those methods that do accept a listener will return immediately, execute asynchronously, and notify the listener whenever the request yielded a response, or failed with an exception.

Note that it is not safe to call RestClient.close() from either of these callbacks.
