Public Member Functions
	SoFileSensor ()
	Default constructor.
	SoFileSensor (SoSensorCB *func, void *data)
	Constructor that takes the callback function and data to be called when the sensor is triggered.
virtual	~SoFileSensor ()
	Destroys the sensor, freeing up any memory associated with it after unscheduling it.
void	addFile (const SbString &filename)
	Add file to be monitored.
void	removeFile (const SbString &filename)
	Remove file from monitored list.
void	clearFiles ()
	Stop monitoring all previously registered files.
SbString	getFilename () const
	Return changed file name.
Public Member Functions inherited from SoTimerSensor
	SoTimerSensor ()
	Default constructor.
	SoTimerSensor (SoSensorCB *func, void *data)
	Constructor that takes the function and data to be called when the sensor is triggered.
virtual	~SoTimerSensor ()
	Destroys the sensor, freeing up any memory associated with it after unscheduling it.
void	setBaseTime (const SbTime &base)
	Sets the base time.
void	setInterval (const SbTime &intvl)
	Sets the interval.
const SbTime &	getBaseTime () const
	Gets the base time.
const SbTime &	getInterval () const
	Gets the interval.
virtual void	schedule ()
	Adds this sensor to the timer queue.
virtual void	unschedule ()
	If this sensor is scheduled, removes it from the timer queue so that it will not be triggered.
Public Member Functions inherited from SoTimerQueueSensor
	SoTimerQueueSensor ()
	Constructor.
	SoTimerQueueSensor (SoSensorCB *func, void *data)
	Constructor that takes standard callback function and data.
const SbTime &	getTriggerTime () const
	Returns the time at which this sensor is scheduled to be triggered.
Public Member Functions inherited from SoSensor
	SoSensor ()
	Constructor.
	SoSensor (SoSensorCB *f, void *d)
	Constructor that takes standard callback function and data.
void	setFunction (SoSensorCB *f, void *userData)
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 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 SbBool	isScheduled () const
	Returns TRUE if this sensor has been scheduled and is waiting in a sensor queue to be triggered.

	This typedef defines the calling sequence for all callbacks from sensors.

Detailed Description

Sensor that triggers a callback each time a file is changed.

File sensors trigger their callback function when a watched file changes. Files are checked at the interval specified with SoTimerSensor::setInterval.

Constructor & Destructor Documentation

SoFileSensor() [1/2]

SoFileSensor::SoFileSensor

(

)

Default constructor.

SoFileSensor() [2/2]

SoFileSensor::SoFileSensor	(	SoSensorCB *	func,
		void *	data )

Constructor that takes the callback function and data to be called when the sensor is triggered.

~SoFileSensor()

virtual SoFileSensor::~SoFileSensor ( )

virtual

Destroys the sensor, freeing up any memory associated with it after unscheduling it.

Member Function Documentation

addFile()

void SoFileSensor::addFile

(

const SbString &

filename

)

Add file to be monitored.

If file does not exist, the method does nothing.

clearFiles()

void SoFileSensor::clearFiles

(

)

Stop monitoring all previously registered files.

getFilename()

SbString SoFileSensor::getFilename ( ) const

inline

Return changed file name.

Note: Only valid when called from the callback function.

Definition at line 89 of file SoFileSensor.h.

removeFile()

void SoFileSensor::removeFile

(

const SbString &

filename

)

Remove file from monitored list.

If file is not being monitored, the method does nothing.
