Have a look at the code examples attached to this issue (
https://github.com/orientechnologies/orientdb/issues/4105). The example
code shows ways to locate an edge, in order to update its properties, but
once you've located it, you can delete it as well.
The simple (no indexes) implementation is this:
String type;
OrientVertex src, tgt;
for (Edge edge : src.getEdges( tgt, Direction.BOTH, type ) ) {
OrientEdge e = (OrientEdge) edge;
e.remove();
break;
}
This is fine as long as you don't have a lot of edges on the source node;
if you have a lot of edges associated with a given node, you'll want to use
heavyweight edges, index them, and then you can use
OrientBaseGraph::getEdges() to search using the index for your edge and
then remove it. (See the linked code for details).
