Bitwise operators in Gremlin

Question

Does Gremlin supports bitwise operators in where() (like property & flag > 0)? Maybe something like where(bitIsSet('property', 2)).

Could not find anything about that in apache docs but it feels at least strange that this basic operation would not be implemented in Gremlin.

Answer 1

No - there are no such steps that behave like a bitwise operator in Gremlin. You could of course use a lambda should your graph support such things (though CosmosDB does not):

gremlin> g.inject([a:-1,b:-1]).filter{(it.get().a & it.get().b) > 0}
gremlin> g.inject([a:00111100,b:00001101]).filter{(it.get().a & it.get().b) > 0}
==>[a:37440,b:577]

it feels at least strange that this basic operation would not be implemented in Gremlin.

Yes - I suppose it's simple but I don't think I've ever heard anyone ask for that functionality since the inception of the project. Gremlin is also missing some other important operators like basic string concatenation and date operations - those have definitely be requested.
