    • The present invention provides a method and system for managing objects in a networked computer system. The networked computer system includes a client and a server. Data is persistently stored in the server in the form of an object. Each object includes attributes and methods and is accessible to a plurality of clients. An object is instantiated and materialized in a client when the client accesses the object. When a client desires to take an action in connection with an object, the server sends an updated object to the client. After receiving the updated object from the server, the client determines whether an existing object has been previously received from the server and stored in the client. If an existing object has not been previously received from the server and stored in the client, the client stores a pointer to the updated object in the client. In either case, the client then merges the existing object and the updated object and notifies windows in the client of changes to the existing object. Thus, the method and system of the present invention enable objects to be efficiently stored and maintained in the client.
    • 本发明提供了一种用于管理联网计算机系统中的对象的方法和系统。 联网计算机系统包括客户端和服务器。 数据以对象的形式永久存储在服务器中。 每个对象包括属性和方法,并且可以被多个客户端访问。 当客户端访问对象时,对象在客户端中实例化和实现。 当客户端希望采取与对象相关的操作时,服务器向客户端发送更新的对象。 在从服务器接收到更新的对象之后,客户机确定是否先前从服务器接收到存在的对象并存储在客户机中。 如果以前没有从服务器接收到存储在客户端中的现有对象,则客户机将存储指向客户端中已更新对象的指针。 在任一情况下,客户端然后合并现有对象和更新的对象,并在客户端中通知Windows对现有对象的更改。 因此,本发明的方法和系统能够使客体中有效地存储和维护对象。
