OElement - asEdge()
This method returns the record as an OEdge

Creating Edges
The OElement
class corresponds to a document record in a Document database. When you use OrientDB as a Graph database, it serves as the superclass to both vertices and edges. In the event that you want a record to serve as an edge, use this method to operate on it an OEdge
instance.
