Logical operators in graph database (neo4j) -

-

edit: possible duplicate of: neo4j logic gate simulation, how to?

i have neo4j database contains options, optionvalues, configurations, products , logicalnodes. in concrete, configuration collection of selected optionvalues, 1 each option. logicalnodes on other hand try link combinations of optionvalues point 1 (or multiple) specific products.

here have example: enter image description here

you can see in graph there 3 options, 2 2 optionvalues , 1 1 optionvalue. every optionvalue linked product through 1 or more logicalnodes. logicalnodes can linked 1 , there 3 types of logicalnodes (and, or, not (not shown)).

now question, know how products related given configuration, not taking logicalnodes account, using cypher: match p = (:configuration {id:"conf1id"})-[r1*]->(pi:productinstance) return pi

however, fail come query uses logicalnodes filter out invalid paths. invalid (sub)path when:

  1. a logicalnode type equals "and" has more incoming :has_logic relations there in path.
  2. a logicalnode type equals "not" has incoming :has_logic relations exist in path.

has ever tried model graph containing logical information in graph , stumbled accross solution?

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

i building xamarin.forms cross platform mobile app, uses monkey.robotics bluetoth low energy functionality. connecting mbed based implimentation of custom gatt service . in xamarin c#, triggers characteristic. canupdate property in monkey.robotics? this standard example c# based on: if (characteristic.canupdate) { characteristic.valueupdated += (s, e) => { debug.writeline("characteristic.valueupdated"); device.begininvokeonmainthread( () => { updatedisplay(characteristic); }); isbusy = false; // spin until first result received }; isbusy = true; characteristic.startupdates(); } this has been working, since changed own custom gatt service connecting to, canupdate property false. property , how triggered? me debugging gatt service code. thanks monkey.robotics open sour

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
