In addition, if the value is a numeric value such as an Integer, the Sample also contains the difference in value between the current sample and the last sample taken of that property. This is presented as the following information:

The atg.service.statistics.SampleEvent class holds an ordered list of Samples, presumably taken at the same point in time. When the Sampler runs, it generates SampleEvents, from which individual Sample objects can be obtained.
