Detailed Description

The Timer class measures the elapsed real time and can be paused and resumed.

It inherits from SGPropertyChangeListener to restart the timer whenever a property change is detected.

Public Member Functions
double	getElapsedTime (void)
	Get the elapsed real time in seconds since the timer was started.
void	pause (bool paused)
	Pause the timer if the paused parameter is true and resume it if the paused parameter is false.
void	start (void)
void	valueChanged (SGPropertyNode *prop) override
	Restart the timer when the listened property is modified.
Public Member Functions inherited from SGPropertyChangeListener
virtual void	childAdded (SGPropertyNode *parent, SGPropertyNode *child)
	Called if child has been added to the given parent.
virtual void	childRemoved (SGPropertyNode *parent, SGPropertyNode *child)
	Called if child has been removed from its parent.
