public interface GraphListener
extends ExtensionPoint

GraphListeners can be used in two different ways: either as an Extension, which will have its onNewHead(FlowNode) fired for every FlowExecution, or by instantiation and being passed to FlowExecution.addListener(GraphListener), in which case only events for that specific FlowExecution will be fired.
