in Gremlin. In OrientDB, I can write my own function called

customUnion

customUnion

customUnion

customUnion

in Gremlin Java API.

I have created the same question on OrientDB: https://github.com/orientechnologies/orientdb/issues/10003

It seems I need to configure the Gremlin server somehow to use my

customUnion

customUnion

function(step), and then I can write my custom traversals in Java to use it in the Java API. However, I cannot find any tutorial for this in TinkerPop3 or orientDB
