Class ClientHandler

  • All Implemented Interfaces:
    org.apache.http.nio.NHttpClientEventHandler
    public class ClientHandler
extends Object
implements org.apache.http.nio.NHttpClientEventHandler
    The client connection handler. An instance of this class is used by each IOReactor, to process every connection. Hence this class should not store any data related to a single connection - as this is being shared.
