[FEATURE] reducing number of links

[xdiscovery]

Hi, I noticed that links created as g.addLink('a','b',data) are different from ('b','a',data).

Is there a native function to compare the links within
g.getLinks(a), and if there are links present, avoid to create new ones which are equivalent?

With nodes I was able to overcome with a solution like writing all the IDs of nodes within an array, and then check with IndexOf() to see if there are already present or not.
But withj links it is different, since I should check within an array of objects, and I am stacked.

I am looking at

and similar but could make a solution work yet.
Any idea?

Hey there

Yes, use graph.hasLink(fromId, toId) function. Internally graph is stored as oriented, so link (a, b) and link (b, a) are different. You might wan to do something like this:

var oldLink = graph.hasLink(a, b) || graph.hasLink(b, a);
if (oldLink) {
  // the link is in the graph, do not add new link
} else {
  // there is no such link
}
