Hi,
addV(Object…) was deprecated because it didn’t support Parameters (that is,
dynamic traversal based parametrization).
g.V().has(’name’,’bob’).as(‘a’).
addV(‘person’).
property(‘name’,’stephen’).
property(‘status’,select(‘a’).by(’status’))
We could support it in Object.., but then stuff looks weird:
g.V().has(’name’,’bob’).as(‘a’).
addV(label,’person’,’name’,’stephen’,‘status’,select(‘a’).by(‘status’))
You really don’t save that much typing and I think its best to be explicit so
traversals are more readable.
To @pieter. In terms of Map arguments. We don’t have any steps/sources that
take Map arguments. I would prefer not to introduce a new data structure
especially when its so fuggly to create in Java.
Thoughts?,
Marko.
