Detailed Description

Instances of this interface provide methods that create instances of StatisticDescriptor and StatisticsType.

Every StatisticsFactory is also a type factory.

A StatisticsFactory can create a statistic of three numeric types: int, long, and double. A statistic (StatisticDescriptor) can either be a gauge meaning that its value can increase and decrease or a counter meaning that its value is strictly increasing. Marking a statistic as a counter allows the Geode Manager Console to properly display a statistics whose value "wraps around" (that is, exceeds its maximum value).
