For example an object `orion_cat` (an instance of `Pet`) could have an attribute `orion_cat.type`, for the column `type`. And the value of that attribute could be, e.g. `"cat"`.

These ORMs also have tools to make the connections or relations between tables or entities.

例如，一个类`Pet`可以表示一个 SQL 表`pets`。

该类的每个*实例对象都代表数据库中的一行数据。*

又例如，一个对象`orion_cat`（`Pet`的一个实例）可以有一个属性`orion_cat.type`, 对标数据库中的`type`列。并且该属性的值可以是其它，例如`"cat"`。

这些 ORM 还具有在表或实体之间建立关系的工具（比如创建多表关系）。

这样，您还可以拥有一个属性`orion_cat.owner`，它包含该宠物所有者的数据，这些数据取自另外一个表。

因此，`orion_cat.owner.name`可能是该宠物主人的姓名（来自表`owners`中的列`name`）。

它可能有一个像`"Arquilian"`(一种业务逻辑)。

     * Note that the returned Iterable holds references to the returned stripes, to avoid
     * error-prone code like:
     *
     * Striped<Lock> stripedLock = Striped.lazyWeakXXX(...)'
     * Iterable<Lock> locks = stripedLock.bulkGet(keys);
     * for (Lock lock : locks) {
     *   lock.lock();
     * }

This caching depends on declaring all inputs to the given generator as part of the cache key. This is extremely error-prone, as there is nothing preventing generators from consuming inputs that are *not* part of the key. When this happens, different clients will non-deterministically get incorrect configuration. This type of bug has historically resulted in CVEs.
