 HttpResponseHandler<Intermediate,Final> handler)

Description copied from interface: HttpClient

Submit a request and process the response with the given response handler.

Note that the Request object passed in to the HttpClient *may* be mutated by the actual client. This is largely done by composed clients, but the contract is that mutation is possible. It is the caller's responsibility to pass in a copy of the Request object if they want to have an object that is not mutated.

Specified by:

go in interface HttpClient

Type Parameters:

Intermediate - The type of the intermediate results from the handler

Final - The type of the final results that the returned ListenableFuture will contain

Parameters:

request - Request to process, this *may* be mutated by the client

handler - An asynchronous response handler that will be used to process results from the http call

Returns:

A listenable future that will eventually provide an object of type Final
