org.rrd4j.ConsolFun

All Implemented Interfaces:

Serializable, Comparable<ConsolFun>, java.lang.constant.Constable

public enum ConsolFun
extends Enum<ConsolFun>

Enumeration of available consolidation functions. Note that data aggregation inevitably leads to loss of precision and information. The trick is to pick the aggregate function such that the interesting properties of your data are kept across the aggregation process.
