Inheritance diagram for SoNodeSensor:
Public Member Functions | |
| SoNodeSensor () | |
| Creation methods. | |
| SoNodeSensor (SoSensorCB *func, void *data) | |
| Creation methods. | |
| virtual | ~SoNodeSensor () |
| Destroys the sensor, freeing up any memory associated with it after unscheduling it. | |
| void | attach (SoNode *node) |
| Makes this sensor detect changes to the given node. | |
| void | detach () |
| Unschedules this sensor (if it is scheduled) and makes it ignore changes to the scene graph. | |
| SoNode * | getAttachedNode () const |
| Returns the node that this sensor is sensing, or NULL if it is not attached to any node. | |
 Public Member Functions inherited from SoDataSensor | |
| SoDataSensor () | |
| Constructors. The second form takes standard callback function and data. | |
| SoDataSensor (SoSensorCB *func, void *data) | |
| virtual | ~SoDataSensor () |
| Destructor. | |
| void | setDeleteCallback (SoSensorCB *f, void *data=NULL) |
| Sets a callback that will be called when the object the sensor is sensing is deleted. | |
| SoNode * | getTriggerNode () const |
| If this is a priority 0 data sensor, returns the node/field that was modified that caused this sensor to trigger. | |
| SoField * | getTriggerField () const |
| Like getTriggerNode(), but returns the field that started notification (NULL if the sensor isn't priority 0 or if notification didn't start at a field). | |
| SoPath * | getTriggerPath () const |
| Returns the path from the node to which this sensor is attached down to the child node that changed. | |
| void | setTriggerPathFlag (bool flag) |
| bool | getTriggerPathFlag () const |
| virtual void | unschedule () |
| Override unschedule() to reset trigNode and trigPath. | |
| virtual void | trigger () |
| Override trigger to reset trigNode and trigPath, if necessary. | |
| virtual void | notify (SoNotList *list) |
| Propagates modification notification through an instance. | |
| virtual void | dyingReference ()=0 |
| This is called when the base (path, field, node, whatever) is deleted. | |
| Public Member Functions inherited from SoDelayQueueSensor | |
| SoDelayQueueSensor () | |
| Constructors. The second form takes standard callback function and data. | |
| SoDelayQueueSensor (SoSensorCB *func, void *data) | |
| virtual | ~SoDelayQueueSensor () |
| Destructor. | |
| void | setPriority (uint32_t pri) |
| Sets the priority of the sensor. | |
| uint32_t | getPriority () const |
| Gets the priority of the sensor. | |
| virtual void | schedule () |
| If this sensor's priority is non-zero, adds this sensor to the list of delay queue sensors ready to be triggered. | |
| virtual void | unschedule () |
| If this sensor is scheduled, removes it from the delay queue so that it will not be triggered. | |
| virtual bool | isScheduled () const |
| Returns TRUE if this sensor has been scheduled and is waiting in the delay queue to be triggered. | |
| virtual bool | isIdleOnly () const |
| This method is overriden by IdleSensors to tell sensor manager that they should only be processed when there really is idle time (and not when the delay queue timeout expires). | |
| void | setCounter (uint32_t c) |
| Set/inquire counter when sensor was last triggered. | |
| uint32_t | getCounter () const |
| Public Member Functions inherited from SoSensor | |
| SoSensor () | |
| Constructors. The second form takes callback function and data. | |
| SoSensor (SoSensorCB *f, void *d) | |
| virtual | ~SoSensor () |
| Virtual destructor so that subclasses are deleted properly. | |
| void | setFunction (SoSensorCB *f) |
| Sets the callback function that is called when the sensor is triggered. | |
| void | setData (void *d) |
| Sets the callback data passed to the callback function. | |
| SoSensorCB * | getFunction () const |
| Returns the callback function that will be called when the sensor is triggered. | |
| void * | getData () const |
| Returns the user-supplied pointer that will be passed to the callback function. | |
| virtual void | schedule ()=0 |
| Schedules the sensor for triggering at the appropriate time. | |
| virtual void | unschedule ()=0 |
| Unschedules sensor to keep it from being triggered. | |
| virtual bool | isScheduled () const =0 |
| Returns whether the sensor is scheduled. | |
| virtual void | trigger () |
| Triggers the sensor, calling its callback function. | |
| virtual bool | isBefore (const SoSensor *s) const =0 |
| This returns TRUE if this sensor should precede sensor s in whichever queue this sensor would be in. | |
| void | setNextInQueue (SoSensor *next) |
| Sets/returns the next sensor in whichever queue the sensor is in. | |
| SoSensor * | getNextInQueue () const |
Additional Inherited Members | |
| Static Public Member Functions inherited from SoDelayQueueSensor | |
| static uint32_t | getDefaultPriority () |
| Returns the default delay queue sensor priority, which is 100. | |
| Static Public Member Functions inherited from SoSensor | |
| static void | initClass () |
| Initialize static members, etc. | |
| Protected Member Functions inherited from SoDataSensor | |
| void | invokeDeleteCallback () |
| Invokes the delete callback. | |
| virtual void | trigger () |
| Triggers the sensor, calling its callback function. | |
| Protected Attributes inherited from SoDelayQueueSensor | |
| bool | scheduled |
| Whether sensor is scheduled. | |
| Protected Attributes inherited from SoSensor | |
| SoSensorCB * | func |
| Callback function. | |
| void * | funcData |
| Data to pass to callback. | |
Detailed Description
Node sensors detect changes to nodes, calling a callback function whenever any field of the node or, if the node is a group node, any children of the node change.
