Enclosing class:

RestActions

public static class RestActions.NodesResponseRestListener<NodesResponse extends BaseNodesResponse & org.elasticsearch.common.xcontent.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); } });
