fr.jgetmove.jgetmove.detector.DivergentDetector

All Implemented Interfaces:

Detector, MultiDetector

public class DivergentDetector
extends java.lang.Object
implements MultiDetector

In charge of detecting Divergent patterns

A divergent pattern is when from a defined set of transactions, these transactions diverge over time(forming a tree).
