Each sensor in the timer queue contains an SbTime 00049 | indicating when the sensor should be triggered. Sensors in the 00050 | timer queue are sorted by their trigger times. 00051 | Each subclass defines public methods for specifying when and how 00052 | to trigger the sensor. 00053 | 00054 | Author(s) : Nick Thompson, Paul Strauss, Gavin Bell 00055 | 00056 ______________ S I L I C O N G R A P H I C S I N C . ____________ 00057 _______________________________________________________________________ 00058 */ 00059 00060 #ifndef _SO_TIMER_QUEUE_SENSOR_ 00061 #define _SO_TIMER_QUEUE_SENSOR_ 00062 00063 #include <Inventor/sensors/SoSensor.h> 00064 #include <Inventor/SbTime.h> 00065 00068 00083 00084 00085 class INVENTOR_API SoTimerQueueSensor : public SoSensor { 00086 00087 public: 00089 SoTimerQueueSensor(); 00090 SoTimerQueueSensor(SoSensorCB *func, void *data); 00091 00093 virtual ~SoTimerQueueSensor(); 00094 00097 const SbTime & getTriggerTime() const { return trigTime; } 00098 00101 virtual void schedule(); 00104 virtual void unschedule(); 00107 virtual SbBool isScheduled() const; 00108 00109 protected: 00112 void setTriggerTime(const SbTime &time); 00113 00117 virtual void trigger(); 00118 00119 SbBool scheduled; 00120 00121 private: 00122 SbTime trigTime; 00123 00126 virtual SbBool isBefore(const SoSensor *s) const; 00127 }; 00128 00129 #endif /* _SO_TIMER_SENSOR_ */
