## Class AbstractResponseHandler<T>

- java.lang.Object
- - org.apache.http.impl.client.AbstractResponseHandler<T>

All Implemented Interfaces:
  ResponseHandler<T>

Direct Known Subclasses:
  BasicResponseHandler, ContentResponseHandler

    @Contract(threading=IMMUTABLE)
    public abstract class AbstractResponseHandler<T>
    extends Object
    implements ResponseHandler<T>

A generic `ResponseHandler` that works with the response entity for successful (2xx) responses. If the response code was >= 300, the response body is consumed and an `HttpResponseException` is thrown.

If this is used with `HttpClient.execute( org.apache.http.client.methods.HttpUriRequest, ResponseHandler)`, HttpClient may handle redirects (3xx responses) internally.

Since:
  4.4
