14.8.4 Checking Out the Latest Snapshots of a Graph

With multiple snapshots of a graph being available and regardless of their source, you can check out a specific snapshot using the PgxSession.setSnapshot() method. You can use the LATEST_SNAPSHOT constant of PgxSession to easily check out the latest available snapshot, as shown in the following example:

• JShell
• Java

opg4j> session.setSnapshot( G, PgxSession.LATEST_SNAPSHOT )
==> null
opg4j> session.getCreationTimestamp()
==> 1453315122685

session.setSnapshot( G, PgxSession.LATEST_SNAPSHOT );
System.out.println(session.getCreationTimestamp());

See the printed timestamp to verify the most recent snapshot.
