Description

There is currently no way to traverse from a Property to its Element in Gremlin. Add an element() operator (and ElementStep) that will accomplish this.

 

// Vertex -> VertexProperty -> Vertex
g.V(1).properties().limit(1).element() => v[1]

// Edge -> Property -> Edge
g.E(2).properties().limit(1).element() => e[2]

// Vertex -> VertexProperty -> Property -> VertexProperty -> Vertex
g.V(1).properties().properties().limit(1).element().element() => v[1] 

 

 

Example use case for this would be service calls that return properties (e.g. full-text search), which could then be traversed to their owning element.
