Interface HttpResponseHandler<IntermediateType,FinalType>

All Known Implementing Classes:

BytesFullResponseHandler, FullResponseHandler, InputStreamResponseHandler, ResponseCookieHandler, RetryIfUnauthorizedResponseHandler, SequenceInputStreamResponseHandler, StatusResponseHandler, ToStringResponseHandler

public interface HttpResponseHandler<IntermediateType,FinalType>

A handler for an HTTP request. The ClientResponse object passed around is used to store state between further chunks and indicate when it is safe to hand the object back to the caller. If the response is chunked, the ClientResponse object returned from handleResponse will be passed in as the first argument to handleChunk(). If the ClientResponse object is marked as finished, that indicates that the object stored is safe to hand off to the caller. This is most often done either from the done() method after all content has been processed or from the initial handleResponse method to indicate that the object is thread-safe and aware that it might be accessed before all chunks come back. Note: if you return a finished ClientResponse object from anything other than the done() method, IntermediateType must be castable to FinalType
