STM requires programmers to demarcate transactional boundaries in source and the system then applies each transaction to the underlying state. STM需要程序员在源代码中划分事务界限,然后系统向底层状态应用每个事务。
So if a transaction reached the end of the dosync block, and the STM sees that another transaction has finished since the current one started, then the current one will be rolled back and run again. Clojure会确保在事务中间该值没有发生改变,因此,如果事务到达了dosync块的结尾,并且,STM可看到在当前事务启动以来有另一事务已经完成了,那么当前事务将回滚并再次运行。
Now you might be wondering about how exactly the STM works here. 此时,您可能想知道STM在此处到底是如何工作的。
The key to using Clojure's STM is wrapping things inside the dosync function. 要使用Clojure的STM,关键是包装dosync函数内部的对象。
