Interface Handler

    • Method Detail

      • init

        boolean init​(Server server,
                     java.lang.String prefix)
        Initializes the handler.
        Parameters:
        server - The HTTP server that created this Handler. Typical Handlers will use Server.props to obtain run-time configuration information.
        prefix - The handlers name. The string this Handler may prepend to all of the keys that it uses to extract configuration information from Server.props. This is set (by the Server and ChainHandler) to help avoid configuration parameter namespace collisions.
        Returns:
        true if this Handler initialized successfully, false otherwise. If false is returned, this Handler should not be used.
      • respond

        boolean respond​(Request request)
                 throws java.io.IOException
        Responds to an HTTP request.
        Parameters:
        request - The Request object that represents the HTTP request.
        Returns:
        true if the request was handled. A request was handled if a response was supplied to the client, typically by calling Request.sendResponse() or Request.sendError.
        Throws:
        java.io.IOException - if there was an I/O error while sending the response to the client. Typically, in that case, the Server will (try to) send an error message to the client and then close the client's connection.

        The IOException should not be used to silently ignore problems such as being unable to access some server-side resource (for example getting a FileNotFoundException due to not being able to open a file). In that case, the Handler's duty is to turn that IOException into a HTTP response indicating, in this case, that a file could not be found.
