uml - Visual Studio Class Diagram - Show two-way associations as a single arrow? -


i'm designing model in c# , have classes refer , each other;

class order {     public icollection<orderitem> childitems { get; set; } }  class orderitem {     public order parentorder { get; set; } }

now, i know order->childitems inverse relationship orderitem->parentorder. can't seem represent on class diagram single arrow 2 arrows, 2 labels, etc. can this;

enter image description here

but i'd prefer single arrow make clear there 1 relationship going on here. possible?

as far know not possible under visual studio 2015. sure arrows express navigability of association. association 1 arrow mean relation if navigeable in 1 direction if not arrows not necessary mean association not navigeable (it depends). if have cross @ end of association mean not navigeable. more info please take @ page 212 of uml 2.5 specification http://www.omg.org/spec/uml/2.5/pdf/

usually tools use different layout when association naviageable or not in both direction in order able see difference directly on diagram.

this not seem case visual studio.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
