org.opennms.netmgt.flows.classification.internal.decision.Classifier

All Implemented Interfaces:

java.lang.Comparable<Classifier>

public class Classifier
extends java.lang.Object
implements java.lang.Comparable<Classifier>

Classifies classification requests.

Classifiers are stored in leaf nodes of classification decision trees. They are derived from RuleDefinitions. They contain a couple of Matchers that are checked during classification. The matchers may do a simplified test because some of their rule's conditions may already have been covered by thresholds along the path through the decision tree. Classifiers have the same sort ordered as their underlying rules.
