Class for monitoring a PerfData Long instrument.
Author:Brian Doherty
Since:1.5
/** * Class for monitoring a PerfData Long instrument. * * @author Brian Doherty * @since 1.5 */
public class PerfLongMonitor extends AbstractMonitor implements LongMonitor {
The buffer containing the data for the long instrument.
/** * The buffer containing the data for the long instrument. */

Constructor to create a LongMonitor object for the long instrument represented by the data in the given buffer.
Params:
  • name – the name of the long instrument
  • u – the units of measure attribute
  • v – the variability attribute
  • supported – support level indicator
  • lb – the buffer containing the long instrument data.
