Houdini 18.5 Executing tasks with PDG/TOPs pdg

pdg.Event class

Represents an event that occurred while the graph was running.

If you set up an event handler on a node, work item or graph (using pdg.Node.addEventHandler, pdg.WorkItem.addEventHandler or pdg.GraphContext.addEventHandler), PDG passes an Event object to the handler when the corresponding event occurs as the PDG graph is cooking.
