Class BlazeGraphEdit

java.lang.Object

com.blazegraph.gremlin.listener.BlazeGraphEdit

public class BlazeGraphEdit
extends Object

An edit consists of an edit action (add or remove), the atomic unit of graph information that was edited (BlazeGraphAtom), and the commit time of the edit. This is the unit of graph information used by the listener and history APIs. Listeners will get edits with no timestamp information, that is because the edits are happening prior to a commit. Listeners will eventually get a commit notification with a timestamp (or a rollback). The history API will provide timestamps, since it is dealing with committed edits that happened in the past.
