indexing - Filter index hits by node ids in Neo4j -


i have set of node id's (set< long >) , want restrict or filter results of query nodes in set. there performant way this?

 set<node> query(final graphdatabaseservice graphdb, final set<long> nodeset) {     final index<node> searchindex = graphdb.index().fornodes("search");     final indexhits<node> hits = searchindex.query(new querycontext("value*"));     // return index hits in given set of node's?  }

wouldn't faster other way round? if nodes set , compare property value looking for?

for (iterator it=nodeset.iterator();it.hasnext();) {    node n=db.getnodebyid(it.next());    if (!n.getproperty("value","").equals("foo")) it.remove(); }

or suggestion

 set<node> query(final graphdatabaseservice graphdb, final set<long> nodeset) {     final index<node> searchindex = graphdb.index().fornodes("search");     final indexhits<node> hits = searchindex.query(new querycontext("value*"));     set<node> result=new hashset<>();     (node n : hits) {        if (nodeset.contains(n.getid())) result.add(n);     }     return result;  }

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
