    `void` | `afterNodeLeft​(ProcessNodeLeftEvent event)` | This listener method is invoked right after a node in a process instance has been left (which is when the node was completed, for example when it performed the task it was designed for).
    `void` | `afterNodeTriggered​(ProcessNodeTriggeredEvent event)` | This listener method is invoked right after a node in a process instance has been triggered (which is when the node was entered, for example when an incoming connection triggered it).
    `void` | `afterProcessCompleted​(ProcessCompletedEvent event)` | This listener method is invoked right after a process instance has been completed (or aborted).
    `void` | `afterProcessStarted​(ProcessStartedEvent event)` | This listener method is invoked right after a process instance has been started.
    `void` | `afterVariableChanged​(ProcessVariableChangedEvent event)` | This listener method is invoked right after the value of a process variable has been changed.
    `void` | `beforeNodeLeft​(ProcessNodeLeftEvent event)` | This listener method is invoked right before a node in a process instance is being left (which is when the node is completed, for example when it has performed the task it was designed for).
    `void` | `beforeNodeTriggered​(ProcessNodeTriggeredEvent event)` | This listener method is invoked right before a node in a process instance is being triggered (which is when the node is being entered, for example when an incoming connection triggers it).
    `void` | `beforeProcessCompleted​(ProcessCompletedEvent event)` | This listener method is invoked right before a process instance is being completed (or aborted).
    `void` | `beforeProcessStarted​(ProcessStartedEvent event)` | This listener method is invoked right before a process instance is being started.
    `void` | `beforeVariableChanged​(ProcessVariableChangedEvent event)` | This listener method is invoked right before the value of a process variable is being changed.
