All Implemented Interfaces:

Serializable, Comparable<FilteringStrategy>

public enum FilteringStrategy
extends Enum<FilteringStrategy>

A FilteringStrategy allows to describe how are managed the undecided cases. An undecided case happen when both supporting Filters and rejecting Filters are found, as well as no supporter nor rejector is found. In such a case, different needs implies different management strategies, and simple strategies are represented by one of these FilteringStrategys.
