You can iterate through all your vertices and update their type property using a sideEffect. For example:

g.V.sideEffect{it.setProperty('TYPE',newTypeValue)}.iterate()

If you have a predefined set of vertices, you can do this:

mySetOfVertices._().sideEffect{it.setProperty('TYPE',newTypeValue)}.iterate()

Or...in pure Groovy:

mySetOfVertices.each{ it.setProperty('TYPE',newTypeValue) }

Is there an advantage to the Gremlin form, or to the pure Groovy form? – PaulMcG Oct 04 '14 at 05:39
