virtual void Scannable::scan ( const epicsTime &  now )

pure virtual

Invoked whenever a scan is due.

The passed 'now' is the deadline time that was used to decide if this item is due 'now', so it should be very close to the current time, and might be cheaper to use than asking for the exact current time.

Implemented in SampleMechanismMonitoredGetEA3, and SampleMechanismGetEA3.
