Can I get the link count between two nodes?

How can I get the link count between two nodes?
we have function to implement more that one link can not be allowed between two nodes when drop a node into a node?

If you have two Nodes, n1 and n2, then it depends on whether you care about the direction that the links are going.

If you don’t care about direction, then:

  n1.findLinksBetween(n2).count

If you do care about direction, then either:

  n1.findLinksTo(n2).count

or:

  n2.findLinksTo(n1).count

Thanks a lot
