The set of all such locking patterns forms a lock hierarchy. 所有此类锁定模式形成了一个锁层次结构。
The model of nested transactions is introduced, which is combined with nested methods invocation in a locking scheme, and we try to give a total locking mechanism integrating the locking of the access methods on single class and class hierarchy. 引入嵌套事务模型,给出一个其和嵌套方法调用结合的加锁方案,并试着给出一个集成单个类上的访问方法和类层次的锁定的总的加锁机制。
