Class Rules

java.lang.Object

org.jeasy.rules.api.Rules

All Implemented Interfaces:

Iterable<Rule>

public class Rules
extends Object
implements Iterable<Rule>

This class encapsulates a set of rules and represents a rules namespace. Rules must have a unique name within a rules namespace.

Rules will be compared to each other based on Comparable.compareTo(Object) method, so Rule's implementations are expected to correctly implement compareTo to ensure unique rule names within a single namespace.
