14.6.2.2 Adding Edges

You can also add edges to a graph using GraphChangeSet.

• JShell
• Java
• Python

opg4j> var changeSet2 = updatedGraph.<Integer>createChangeSet()

opg4j> changeSet2.addEdge(333, 42).setProperty("cost", 42.3)
opg4j> changeSet2.addEdge(42, 99)

opg4j> var updatedGraph2 = changeSet2.build()

import oracle.pgx.api.*;

GraphChangeSet<Integer> changeSet2 = graph.createChangeSet();

changeSet2.addEdge(333, 42).setProperty("cost", 42.42);
changeSet2.addEdge(42, 99);

PgxGraph updatedGraph2 = changeSet2.build();

from pypgx.api import *

change_set_2 = graph.create_change_set()
changeSet2.add_edge(333, 42).set_property("cost", 42.42)
changeSet2.add_edge(42, 99)
updated_graph_2 = change_set_2.build()

Note that by calling changeSet2.build(), you created a brand new graph with a unique name assigned by the graph server (PGX). If need be, you can specify a name argument to the build() method.

Additionally, you can create a new snapshot on top of the current graph with the buildNewSnapshot() method. See Creating a Snapshot via ChangeSet for more information.
