public SoPath GetTriggerPath()

Public Function GetTriggerPath As SoPath

public:
SoPath^ GetTriggerPath()

member GetTriggerPath : unit -> SoPath 

Return Value

Because recreating the path to the node that changed is relatively expensive, setTriggerPathFlag(true) must be called before the sensor is scheduled. If it is not called, or if the sensor wasn't triggered because a node changed, this returns NULL. NULL is also returned if this is not a priority 0 sensor.
