5.4.10 Creating Edges

To create an edge, use these Oracle Property Graph methods:

• OraclePropertyGraph.addEdge: Adds an edge instance to a graph.

• OracleEdge.setProperty: Assigns a key-value property to an edge.

The following code fragment creates two vertices (v1 and v2) and one edge (e1).

// Add vertices v1 and v2
Vertex v1 = opg.addVertex(1l);
v1.setProperty("name", "Alice");
v1.setProperty("age", 31);

Vertex v2 = opg.addVertex(2l);  
v2.setProperty("name", "Bob");
v2.setProperty("age", 27);

// Add edge e1
Edge e1 = opg.addEdge(1l, v1, v2, "knows");
e1.setProperty("type", "friends");
