摘要
持久化对象查询是大多数面向对象系统的基本任务之一,但传统的常规查询方法存在着可重用性差、可维护性不佳的缺陷。针对这个问题,提出了"约束条件逻辑"的新概念,并在此基础上对原始的资源库——规约方法进行改造,从而提出了一种新的持久化对象查询方法:扩展的资源库——规约方法。试验表明,该方法具有良好的可重用性与可维护性。
Querying persistent objects is a fundamental task in most object - oriented systems, but the ordinary query method is considered to be lacking in reusability and maintainability. Improves the original repository- specification method base on the new conception： ＂where condition logic＂, and it presents a new query method： extended repository- specification method, which can be applied to persistent objects. And experiments show that the method has much higher reusability and maintainability.
