All Implemented Interfaces:

RuleExpression

public class MetaRuleExpression
extends AccumulatingBSFRuleExpression

Expression implementation for "meta rules". A "meta rule" consists of a sequence of subordinate rule evaluations each processed according to an associated modifier:

next

proceed with rule evaluation

true

if this rule evaluates to true, then return the responsibilities associated with the rule

false

if this rule evaluates to false, then return the responsibilities associated with the rule

E.g.

bizRule1: next; bizRule2: true; bizRule3: false
