    • A system and method for managing cachable entities (i.e., entities stored in a cache and/or entities which may be stored in a cache) in a data processing application. In one aspect, a method for managing cachable entities comprises the steps of analyzing program code to determine if there is at least one statement which affects a desirability of performing at least one cache transaction; and performing the at least one cache transaction if it is desired. In another aspect, a program analysis tool statically analyzes program code to locate points where object state changes occur, where objects are created and where objects are deleted, and then generates regularized dependencies at such points for and employing the dependencies to invalidate dependent cached queries. Query specific keys are generated to insert query results into and retrieve query results from a dependency managed cache. Regularized dependencies are generated at the object query points and are attached to query results inserted into a dependency managed cache, which facilitates consistency of query results from the dependency managed cache.
    • 一种用于在数据处理应用中管理可高速缓存的实体(即,存储在高速缓存中的实体和/或可存储在高速缓存中的实体)的系统和方法。 一方面,一种用于管理可高速缓存实体的方法包括以下步骤:分析程序代码以确定是否存在影响执行至少一个高速缓存事务的可取性的至少一个语句; 以及如果需要,则执行所述至少一个高速缓存事务。 在另一方面,程序分析工具静态地分析程序代码以定位发生对象状态改变的点,其中创建对象并删除对象,并且然后在这些点处生成规则化的依赖关系并使用依赖关系来使依赖性缓存查询无效。 生成查询特定的密钥,以将查询结果插入并从依赖性管理缓存中检索查询结果。 在对象查询点生成正则化依赖关系,并附加到插入依赖性管理缓存中的查询结果,这有助于依赖性管理缓存的查询结果的一致性。
