OElement - asEdge()

This method returns the record as an OEdge instance.

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.

Syntax

Optional<OEdge> OElement().asEdge()

Return Value

When the record corresponding to this OElement instance is an edge, this method returns an OEdge instance. In the event that the record is a document or vertex, (that is, not an edge), it returns an empty Optional instance.
