### Question:
RestSinkConnectorConfig extends AbstractConfig { public static ConfigDef conf() { String group = "REST"; int orderInGroup = 0; return new ConfigDef() .define(SINK_METHOD_CONFIG, Type.STRING, SINK_METHOD_DEFAULT, new MethodValidator(), Importance.HIGH, SINK_METHOD_DOC, group, ++orderInGroup, ConfigDef.Width.SHORT, SINK_METHOD_DISPLAY, new MethodRecommender()) .define(SINK_HEADERS_LIST_CONFIG, Type.LIST, Collections.EMPTY_LIST, Importance.HIGH, SINK_HEADERS_LIST_DOC, group, ++orderInGroup, ConfigDef.Width.SHORT, SINK_HEADERS_LIST_DISPLAY) .define(SINK_URL_CONFIG, Type.STRING, NO_DEFAULT_VALUE, Importance.HIGH, SINK_URL_DOC, group, ++orderInGroup, ConfigDef.Width.SHORT, SINK_URL_DISPLAY) .define(SINK_RETRY_BACKOFF_CONFIG, Type.LONG, SINK_RETRY_BACKOFF_DEFAULT, Importance.LOW, SINK_RETRY_BACKOFF_DOC, group, ++orderInGroup, ConfigDef.Width.NONE, SINK_RETRY_BACKOFF_DISPLAY) .define(SINK_HTTP_MAX_RETRIES_CONFIG, Type.INT, SINK_HTTP_MAX_RETRIES_DEFAULT, Importance.LOW, SINK_HTTP_MAX_RETRIES_DOC, group, ++orderInGroup, ConfigDef.Width.NONE, SINK_HTTP_MAX_RETRIES_DISPLAY) .define(SINK_HTTP_CODES_WHITELIST_CONFIG, Type.STRING, SINK_HTTP_CODES_WHITELIST_DEFAULT, Importance.LOW, SINK_HTTP_CODES_WHITELIST_DOC, group, ++orderInGroup, ConfigDef.Width.NONE, SINK_HTTP_CODES_WHITELIST_DISPLAY) .define(SINK_HTTP_CODES_BLACKLIST_CONFIG, Type.STRING, SINK_HTTP_CODES_BLACKLIST_DEFAULT, Importance.LOW, SINK_HTTP_CODES_BLACKLIST_DOC, group, ++orderInGroup, ConfigDef.Width.NONE, SINK_HTTP_CODES_BLACKLIST_DISPLAY) .define(SINK_REQUEST_EXECUTOR_CONFIG, Type.CLASS, SINK_REQUEST_EXECUTOR_DEFAULT, Importance.LOW, SINK_REQUEST_EXECUTOR_DOC, group, ++orderInGroup, ConfigDef.Width.NONE, SINK_REQUEST_EXECUTOR_DISPLAY) .define(SINK_DATE_FORMAT_CONFIG, Type.STRING, SINK_DATE_FORMAT_DEFAULT, Importance.LOW, SINK_DATE_FORMAT_DOC, group, ++orderInGroup, ConfigDef.Width.NONE, SINK_DATE_FORMAT_DISPLAY) ; } protected  RestSinkConnectorConfig(ConfigDef config, Map<String, String> parsedConfig);  RestSinkConnectorConfig(Map<String, String> parsedConfig); static ConfigDef conf(); String getMethod(); String getUrl(); Long getRetryBackoff(); Map<String, String> getRequestHeaders(); int getMaxRetries(); RequestExecutor getRequestExecutor(); ResponseHandler getResponseHandler();  }### Answer:
@Test public void doc() { System.out.println(RestSinkConnectorConfig.conf().toRst()); }
