Question
I have a set of vertices which have the same property 'TYPE'. How to update this property for all the given set of vertices.
Solution
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) }
