Functions - addEdge()

This method adds an edge to the database.

Adding Edges

When working with a Graph database, whether transactional or non-transactional, when you want to add an edge to the graph, use this method. This adds a new edge record to the database and ensures that the relevant vertices are also updated, keeping the graph consistent.

Syntax

var edge = db.addEdge(<record-id>, <out>, <in>, <label>)

• <record-id> Defines the Record ID.
• <out> Defines the out vertex.
• <in> Defines the in vertex.
• <label> Defines a name or label for the edge.

NOTE: You can use the getVertex() method to retrieve the in and out vertices to connect the edge.
