How to use Spring Data CouchBase 'findAll(Iterable<ID>)' Method? -


i'm trying use spring-data-couchbase.

i want list findall(iterable) method. set view 'all' production view.

but, meet exception. how can use findall(iterable) method?

below sample code , exception.

document class:

@document public class user {     @id     private string id;     private string userseq; }

repository class :

public interface userrepository extends couchbaserepository<user, string> { }

service class:

//list<string> same result & exception. set<string> friendset = new hashset<string>(); friendset.add("user8"); friendset.add("user6");  userrepository.findall(friendset)

exception:

you have quote id:s before call findall(...).

    set<string> friendset = new hashset<string>();     friendset.add("\"user8\"");     friendset.add("\"user6\"");

if id:s aren't quoted keys parameter sent couchbase server [user8, user6] isn't valid json, hence exception. pretty surprising behaviour...

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
