Under the hood , operations on atomic variables get turned into the hardware primitives that the platform provides for concurrent access , such as compare - and - swap 在表面之下,原子变量的操作会变为平台提供的用于并发访问的硬件原语,比如比较并交换。
The transaction support in jdbc 2 gave developers control over concurrent access to their data , thereby ensuring that persisted data is always in a consistent state Jdbc 2中的事务支持让开发人员可以控制对数据的并发访问,从而保证持续数据总是保持一致的状态。
In particular , nearly every modern processor has instructions for updating shared variables in a way that can either detect or prevent concurrent access from other processors 特别是,几乎每个现代处理器都有通过可以检测或阻止其他处理器的并发访问的方式来更新共享变量的指令。
This access method is unusual in that it provides record level locking . this can provide beneficial performance improvements in applications requiring concurrent access to the queue 这种访问方式与众不同处在于他提供记录级别的锁.当程序需要并发的访问队列时,这一点可以提高性能
Serialization does not offer any transaction control mechanisms per se , so it cannot be used within applications that need concurrent access without making use of additional apis 序列化本身并不提供任何事务控制机制,因此不能在那些需要并发访问从而不使用辅助api的应用程序中使用它。
Partitioned table spaces allow a db2 utility to process one partition of the data at a time , thus enabling concurrent access for other jobs or applications on the other partitions :分区表空间允许db2实用程序一次处理一个分区的数据,这样其他任务或应用程序就可以并发地对其他分区进行访问。
An innovative new software program that combines the power of speech recognition with concurrent access to other technologies , and offers students a writing solution with distinct advantages 这促使我们开发了speakq ,一种创新的能让语音识别和其它多种技术协同工作的软体,这种独特的优势解决了学生们的写作问题。
If you are documenting a conditionally thread - safe class , you should not only document that it is conditionally thread - safe , but also which sequences of operations must be protected from concurrent access 如果对一个有条件线程安全类进行记录,那么您应该不仅要记录它是有条件线程安全的,而且还要记录必须防止哪些操作序列的并发访问。
It uses the ood method to decompose the design in structural stage . during collaborative design process , when different users share a common object , concurrent access control is the necessity to keep the shared object consistent 规划利用面向对象的方法使工程设计问题变成了一个类层次结构,复杂的工程设计问题被分解成为简单的设计对象,分配不同的用户进行协同设计。
This module is in charge of the form and organization of the log record , log page and log file . this module is also used to control the concurrent access of the log records and provides rapid read / write to the upper level 日志管理模块设计日志记录、日志页以及日志文件的格式和组织方法;该模块同时管理多个服务线程对日志记录的并发访问,并且向上层提供快速读写日志的接口。
