public static class RestActions.NodesResponseRestListener<NodesResponse extends BaseNodesResponse & ToXContent> extends RestBuilderListener<NodesResponse>
NodesResponseRestBuilderListener automatically translates any BaseNodesResponse (multi-node) response that is
ToXContent-compatible into a RestResponse with the necessary header info (e.g., "cluster_name").
This is meant to avoid a slew of anonymous classes doing (or worse):
client.admin().cluster().request(nodesRequest, new RestBuilderListener<NodesResponse>(channel) {
public RestResponse buildResponse(NodesResponse response, XContentBuilder builder) throws Exception {
return RestActions.nodesResponse(builder, ToXContent.EMPTY_PARAMS, response);
}
});
