java - 如何使用流访问父对象变量

Question

我需要过滤掉子对象后，才能访问groupCoverPeriod对象。如何使用流进行此操作..我编写了以下代码，但在** groupCoverPeriod *处收到错误（请忽略前缀）并在代码中加上**）

       boolean isCalMethodCal=newInsurancePeriod.getPensionGroup().getGroupCoverPeriods().stream()
                .filter(groupCoverPeriod -> groupCoverPeriod.getStartDate().isBefore(newInsurancePeriod.getStartDate()) && (
                        Objects.isNull(newInsurancePeriod.getEndDate()) || groupCoverPeriod.getStartDate().isAfter(newInsurancePeriod.getEndDate())))
                .filter(groupCoverPeriod -> !groupCoverPeriod.getCalcMethod().equalsIgnoreCase("kiinnitetty"))
                .flatMap(groupCoverPeriod -> groupCoverPeriod.getInsuranceCoverInfos().stream())
                .filter(ici -> ici.getBenefitType().equalsIgnoreCase("VE"))
                        .anyMatch(ici -> !ici.getOverServiceNotification().equals(true)
                                || !ici.getConsideredEarningsInRTAge().equals(true)
                                || (ici.getConsideredStatutoryEarningsInRTAge().equalsIgnoreCase("6300") && beginDate >= 6300)
                                || (ici.getConsideredStatutoryEarningsInRTAge().equalsIgnoreCase("6500") && beginDate >= 6500)
                                || (ici.getDeferralIncreaseSupplementaryPension().equalsIgnoreCase("ei") || ici.getDeferralIncreaseSupplementaryPension().equalsIgnoreCase("elakemuunnos"))
                                || (**groupCoverPeriod**.getTerminationAge().equalsIgnoreCase("yhteinen") && groupCoverPeriod.getGroupSuplInsuranceRTAge() >= beginDate)
                                || (**groupCoverPeriod**.getTerminationAge().equalsIgnoreCase("yksilollinen") && insurancePeriod.getPersonsCoverInfo().getAgeForSupplementaryPension() >= beginDate)
                                || (**groupCoverPeriod**.getTerminationAge().equalsIgnoreCase("wtyel_vahvistettu") && Integer.parseInt(ykService.getPersonBirthYear(newInsurancePeriod.getPerson().getPersonNumber())) >= beginDate)
                                || (**groupCoverPeriod**.getTerminationAge().equalsIgnoreCase("wtyel_ennustettu") && Integer.parseInt(ykService.getPersonBirthYear(newInsurancePeriod.getPerson().getPersonNumber())) >= beginDate));

我什至尝试过，但这并没有返回预期的结果。

newInsurancePeriod.getPensionGroup().getGroupCoverPeriods().stream()
                .filter(groupCoverPeriod -> groupCoverPeriod.getStartDate().isBefore(newInsurancePeriod.getStartDate()) && (
                        Objects.isNull(newInsurancePeriod.getEndDate()) || groupCoverPeriod.getStartDate().isAfter(newInsurancePeriod.getEndDate())))
                .filter(groupCoverPeriod -> !groupCoverPeriod.getCalcMethod().equalsIgnoreCase("kiinnitetty"))
                .forEach(groupCoverPeriod -> {
                        boolean isCalMethodCal = groupCoverPeriod.getInsuranceCoverInfos().stream()
                                .filter(ici -> ici.getBenefitType().equalsIgnoreCase("VE"))
                                .anyMatch(ici -> !ici.getOverServiceNotification().equals(true)
                                        || !ici.getConsideredEarningsInRTAge().equals(true)
                                        || (ici.getConsideredStatutoryEarningsInRTAge().equalsIgnoreCase("6300") && beginDate >= 6300)
                                        || (ici.getConsideredStatutoryEarningsInRTAge().equalsIgnoreCase("6500") && beginDate >= 6500)
                                        || (ici.getDeferralIncreaseSupplementaryPension().equalsIgnoreCase("ei") || ici.getDeferralIncreaseSupplementaryPension().equalsIgnoreCase("elakemuunnos"))
                                        || (groupCoverPeriod.getTerminationAge().equalsIgnoreCase("yhteinen") && groupCoverPeriod.getGroupSuplInsuranceRTAge() >= beginDate)
                                        || (groupCoverPeriod.getTerminationAge().equalsIgnoreCase("yksilollinen") && insurancePeriod.getPersonsCoverInfo().getAgeForSupplementaryPension() >= beginDate)
                                        || (groupCoverPeriod.getTerminationAge().equalsIgnoreCase("wtyel_vahvistettu") && Integer.parseInt(ykService.getPersonBirthYear(newInsurancePeriod.getPerson().getPersonNumber())) >= beginDate)
                                        || (groupCoverPeriod.getTerminationAge().equalsIgnoreCase("wtyel_ennustettu") && Integer.parseInt(ykService.getPersonBirthYear(newInsurancePeriod.getPerson().getPersonNumber())) >= beginDate));

您的过滤器似乎到处都有。为什么要再次检查组保障期？

尝试重新排列代码，如下所示：

Predicate<GroupCoverPeriod> groupCoverPredicates = // all group cover predicates here filter predicates here
Predicate<InsuranceCoverInfo> iciPredicates = // all insurance cover info filter predicates here;

boolean isCalMethodCal = newInsurancePeriod.getPensionGroup().getGroupCoverPeriods().stream()
        .filter(groupCoverPeriod -> groupCoverPredicates)
        .flatMap(groupCoverPeriod -> groupCoverPeriod.getInsuranceCoverInfos().stream())
        .anyMatch(ici -> iciPredicates);
