Method Detail

earlyEvaluate

protected java.lang.Boolean earlyEvaluate(UserModel user,
                                          BTGRuleModel rule,
                                          BTGEvaluationContext context,
                                          BTGRuleResultModel lastRuleResult)

This method allows to make evaluation based on some predefined rules, without actually trying to do full evaluation.

Returns:

Any non-null value is the evaluation result. Null value means that evaluation should proceed as normal.
