Predicates

They're the thing which gets us to the thing.

BooleanExpression isBonus = QSalaryDetail.salaryDetail.salaryName.equalsIgnoreCase("Bonus");
BooleanExpression isGreaterThanThreshold = QSalaryDetail.salaryDetail.salary.goe(paydayThreshold);
BooleanExpression predicate = isBonus.and(isGreaterThanThreshold);

    QSalaryDetail.salaryDetail.salaryName.eq(salary.getSalaryName());

    if (!other.salaryName().equalsIgnoreCase("other")) {
        booleanBuilder.and(QSalaryDetail.salaryDetail.salary.gt(thresholdForPayPeriod));
    }
