Description

BeanListHandler handles to list of the bean class itself only.
If want list of the bean's base class or interface, two steps of cast are needed.

// Bean is super class or interface of BeanImpl
BeanListHandler<BeanImpl> blh = new BeanListHandler<BeanImpl>(BeanImpl.class);
List<BeanImpl> beanImplList = queryRunner.query(sql, blh);
List<Bean> beanList = (List<Bean>) ((List<?>) beanImplList);

I want to change BeanListHandler to be able to handle to list of the bean's super class or interface;

// Bean is super class or interface of BeanImpl
BeanListHandler<Bean> blh = new BeanListHandler<Bean>(BeanImpl.class);
List<Bean> beanList = queryRunner.query(sql, blh);
for (Bean bean : beanList) {
    assert bean == null || bean.getClass() == BeanImpl.class;
}
