Generated DSL related
I am new to gremlin and I am struggling with a problem with custom dsl. Followed with example I can create a socialTraversalDSL to provide user to use, something like
g.person("one").knows("another") it's good, but how to change the Traversal type when the given step is changed. e.g . another TwitterTraversalDSL.and user can do something like g.person("one").twitter().follows("another") when follows step is not a part of socialTraversalDSL ..How can I achieve this with java ~ looking forward to your replySolution:Jump to solution
Welcome to TinkerPop! In answer to your question, I'm afraid that the DSL annotation model isn't flexible enough to handle something like that. I believe that DSLs can inherit one another, like, you could extend TwitterTraversalDSL from SocialTraversalDSL which would extend from GraphTraversal (i've not done that myself, but i think others have had success with that). But I don't think you can have two DSLs easily know and reference one another. That might even be problematic if you were to writ...

Thanks for relpying~ ok It seems I have to back to my own dsl then
you might want to look at the DSL annotation processor code. it might take a bit of time to understand if you don't know javapoet but maybe you could modify it to do what you want to do without too much work.
Thanks a lot I will dive into it~
