Re: [orientdb] Restrict ShortestPath and Dijkstra to a specific Edge class

Thanks for the (very very) quick reply ! I've already implemented my little hack (I knew it was one :) ). I deploy it on our dev server so that other developers can work on top of it and I'll start working on a PR right away. I loved working with OrientDB so far and your reply make me wanted to d

Hi guys, you have two easy ways to do this (the first one is easier IMHO): 1. copy Dijkstra implementation to another class (put it in the same package and give it another name), do your changes and register it in com .orientechnologies.orient.graph.sql.functions.OGraphFunctionFactory. Then, in th

Hi Luigi. Thanks for the answer. I had a quick look at the code and it seems that adding an extra check and parameter to the getNeighbors function in the OSQLFunctionPathFinder class could do the trick. But it's a while since I've been in Java-Land and I'm a bit unsure on how I actually would

Yeah, that's what I was suggesting, didn't know about your additional constraint (C -> many B's). In that case you could add an edge C-> A and make that unique if that fits your use-case. But I don't think orient has any index or other thing that will ensure uniqueness of multiple edges in a

Hey, sorry missed that. So these bytes are part of the record response of this command (synch-result-content, can only be a record). And the "signature" of a record is "(record-type:byte)(cluster-id:short)(cluster-position:long)(record-version:int)(record-content:bytes)" and the short before

Keith, Thanks for taking the time to answer it. Do you mean: create index hasC.in unique Or create another edge from C back to B, and make it unique? Anyway, I may be mistaken but I don't think that work. Adding that unique index from C back to B would guarantee a single B for each C, is that
