How to efficiently create a vertex with a label an

问题:

I want to create a vertex with a given label and some properties. Since the g.addVertexWithLabel() method only takes the label as an argument and I cannot find any v.addLabel() method, it seems that I have to add the properties one by one after creating the vertex.

Or am I missing something here?

No. As of Titan 0.5.4, there is no API that allows you to add it all at once. In fact, even the Gremlin Groovy sugar of:

g.addVertex([name:"stephen"]) 

just calls Element.setProperty(k,v) for each key/value pair in the Map. In TinkerPop3 and Titan 0.9/1.0, you can do:

g.addVertex(T.label,"person","name","stephen")

so it is a bit nicer assuming you are using the newer version.
