Mike Personick updated TINKERPOP-2713:
--------------------------------------
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.
{code:java}
// 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] {code}
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.
