摘要： A method for manipulating objects in isolation, in accordance with the invention, includes providing a shared object, B, from an object provider for use on a distributed object system. A new class of objects are provided which include a facade object, Bf, for B and a versionable representation object, Bv, for B wherein Bf supports a same interface as B. B is permitted to be manipulated in a given context isolated from other contexts for the object B wherein the object provider and an object user are unaware of the production and manipulation of the new class of objects. Method invocations on Bf in the given context are delegated to Bv to associate an instance of Bv with the given context such that one or more versions of object B are persistently maintained in the distributed object system.

摘要： A method is disclosed for performing a query in a Long Running Business Process framework system. The method has steps of: (a) generating a modified base search condition from a base search condition; (b) generating a facade search condition for specifying that a primary key be a primary key of a version object, from a visible version sub-query, that satisfies the generated modified base query; and (c) determining a unit of work context, and requesting all facades that satisfy the generated facade search condition. The step of generating a modified base search condition from a base search condition includes a step of replacing names representing base objects, for which version and facade objects will be made, with a corresponding visible version sub-query.
摘要翻译：公开了一种在长时间运行的业务流程框架系统中执行查询的方法。该方法具有以下步骤：（a）从基本搜索条件生成修改的基本搜索条件; （b）从可见版本子查询生成满足生成的修改的基本查询的生成用于指定主键为版本对象的主键的外观搜索条件; 和（c）确定工作单元的上下文，并请求满足所生成的门面搜索条件的所有立面。从基本搜索条件生成修改的基本搜索条件的步骤包括将用于对应于哪个版本和外部对象的基础对象的名称替换为对应的可见版本子查询的步骤。
