c# - Sones GraphDB Query Returning Error -

-

i following tutorial here:

http://developers.sones.de/wiki/doku.php?id=quickreference:fiveminuteguide

but when copy , paste command in webshell

create vertices     abstract entity attributes (string name),    university extends entity attributes(set<student> students),    city extends entity attributes(set<university> universities),    student extends entity attributes(integer age) backwardedges(university.students studiesat)

the output generates error:

graphdb@localhost [gql-mode] > create vertices abstract entity attributes (string name), university extends entity attributes(set<student> students), city extends entity attributes(set<university> universities), student extends entity attributes(integer age) backwardedges(university.students studiesat) {   "query": "create vertices abstract entity attributes (string name), university extends entity attributes(set students), city extends entity attributes(set universities), student extends entity attributes(integer age) backwardedges(university.students studiesat)",   "result": "failed",   "duration": [     0,     "ms"   ],   "warnings": [],   "errors": [     {       "code": "sones.graphdb.errors.error_gqlsyntax",       "description": "syntax error in query: [create vertices abstract entity attributes (string name), university extends entity attributes(set students), city extends entity attributes(set universities), student extends entity attributes(integer age) backwardedges(university.students studiesat)]\n\n gql: [syntax error, expected: index,types,abstract,type,]\n\nat position: 1, 8"     }   ],   "results": [] }

instead of expected result:

{   "query": "create vertices abstract entity attributes (string name), city extends entity attributes(set universities), university extends entity attributes(set students), student extends entity attributes(integer age) backwardedges(university.students studiesat)",   "result": "successful",   "duration": [     660,     "ms"   ],   "warnings": [],   "errors": [],   "results": [     {       "dbtype": "entity",       "uuid": "f1cf505d-3dc9-4ec0-b777-ca1c0075d835",       "revision": "20102110.124020.0492167(8edd08775ce5754581140b203163f93d)",       "edition": "defaultedition"     },     {       "dbtype": "city",       "uuid": "89dc4d40-2046-4c0b-8599-6c0665ae62a5",       "revision": "20102110.124020.1952135(8edd08775ce5754581140b203163f93d)",       "edition": "defaultedition"     },     {       "dbtype": "university",       "uuid": "274f1216-7ba0-409d-b466-668157b2a6ee",       "revision": "20102110.124020.3592086(8edd08775ce5754581140b203163f93d)",       "edition": "defaultedition"     },     {       "dbtype": "student",       "uuid": "7dec86d3-c62d-49cc-840a-93203bb821dc",       "revision": "20102110.124020.5402167(8edd08775ce5754581140b203163f93d)",       "edition": "defaultedition"     }   ] }

so what's problem (i used own lastest binary version didn't compile myself).

they don't have forum :(.

examples on site out of date. i've heard sones gmbh (creators of sonesdb) out of money, product may dead.

the correct query of sample sonesdb 2.0+ is:

create vertex types        abstract entity attributes (string name),        university extends entity attributes(set<student> students),        city extends entity attributes(set<university> universities),        student extends entity attributes(int32 age) incomingedges(university.students studiesat)

there no more statement "create vertices", it's called "create vertex types"

integer type - int32

backwardedges - incomingedges

cheatsheet sonesdb 2.0+ can see here. see, there correct information.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
