Interface ResponseHeadersProcessor

All Known Implementing Classes:

ProcessStateProcessor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ResponseHeadersProcessor

Interface to parse data from the responses headers of a DMR response. This is not about HTTP response headers, but related to DMR responses only.

In standalone mode there's only a single response-headers node in the DMR response, whereas in domain mode the response headers are scoped to a specific server group, host and server. The process(Header[]) method will only receive the response-headers payload w/o the surrounding 'noise'.

Standalone Mode:

 {
     "outcome" => "success",
     "response-headers" => {
         "foo" => "bar",
         ...
     }
 }
 

Domain Mode:

 {
     "outcome" => "success",
     "server-groups" => {
         "main-server-group" => {
             "host" => {
                 "master" => {
                     "server-one" => {
                         "response" => {
                             "outcome" => "success",
                             "response-headers" => {
                                 "foo" => "bar",
                                 ...
                             }
                         }
                     },
                     "server-two" => {
                         "response" => {
                             "outcome" => "success",
                             "response-headers" => {
                                 "foo" => "bar",
                                 ...
                             }
                         }
                     }
                 }
             }
         }
     }
 }
