// .NAME vtkExecutionTimer - Time filter execution
//
// .SECTION Description
//
// This object monitors a single filter for StartEvent and EndEvent.
// Each time it hears StartEvent it records the time. Each time it
// hears EndEvent it measures the elapsed time (both CPU and
// wall-clock) since the most recent StartEvent. Internally we use
// vtkTimerLog for measurements.
//
// By default we simply store the elapsed time. You are welcome to
// subclass and override TimerFinished() to do anything you want.

// Set/get the filter to be monitored. The only real constraint
// here is that the vtkExecutive associated with the filter must
// fire StartEvent and EndEvent before and after the filter is
// executed. All VTK executives should do this.
