摘要： To support values of properties, a class includes fields to support values in preallocated memory space and with an option data structure which supports, in instances of the class, references to option values without preallocation of memory space. The field and option values are accessed in an instance object of the class using expressions of the same syntactic form. During compilation, the compiler checks the type of an option value against a type description within the option data structure. If a value has not been set for an instance object, a get operation results in getting of the default value for the class. Different classes may support different forms of data structures such as a linked list or a hash table. During compilation, a method call to an object is encoded without regard to the form of the option data structure. When an option value is changed, a change handler identified by an option binding of the data structure is processed. That option binding may be located by first searching a mapping data structure for a previously computed mapping to the option binding or by computing the mapping to the option binding. An option value may be set in an option data structure from an initialization expression which includes the name of the option value and, as an argument, the option value. Nonlocal option values may be applied to plural objects in a nonlocal option hierarchy such as a graphical hierarchy.
摘要翻译：为了支持属性的值，类包括支持预分配内存空间中的值的字段，以及在类的实例中支持对选项值的引用而不预分配内存空间的选项数据结构。使用相同句法形式的表达式，在类的实例对象中访问字段和选项值。在编译期间，编译器会根据选项数据结构中的类型描述来检查选项值的类型。如果没有为实例对象设置值，则get操作将导致获取该类的默认值。不同的类可以支持不同形式的数据结构，例如链表或散列表。在编译期间，对对象的方法调用被编码，而不考虑选项数据结构的形式。当选项值更改时，将处理由数据结构的选项绑定所标识的更改处理程序。可以通过首先将映射数据结构搜索先前计算的映射到选项绑定或通过计算到选项绑定的映射来定位该选项绑定。可以从包含选项值的名称和作为参数的选项值的初始化表达式在选项数据结构中设置选项值。非本地选项值可以应用于非本地选项层次结构中的多个对象，例如图形层次结构。

摘要： A licensing system and method for deploying digital content is provided. A client system can download the digital content from the server and, if a valid license for the content is also found on the server, software may be permitted to run digital content. The license is stored in a location that is separate from the content. The license can be located using the URL address of the content. The system can locate the license on the server and determine whether the license covers the content. Content that is covered by the license can be processed and rendered. The content can be any form of digital media, such as a computer application.
摘要翻译：提供了许可系统和部署数字内容的方法。客户端系统可以从服务器下载数字内容，并且如果在服务器上也找到内容的有效许可证，则可以允许软件运行数字内容。许可证存储在与内容分开的位置。可以使用内容的URL地址找到许可证。系统可以在服务器上定位许可证，并确定许可证是否涵盖内容。可以处理和呈现许可证所涵盖的内容。内容可以是任何形式的数字媒体，例如计算机应用。

摘要： Mobile code, such as an applet, is permitted to create a network connection with a content server on a network, without restricting the applet only to connections from the computer from which it was downloaded. This is achieved in accordance with the principles of the present invention by using network restriction software in the execution engine or runtime system under which the applet executes. When the applet attempts to create a network connection to a content server, the network restriction software checks a name file on the content server for the presence of an entry whose name corresponds to the name of the computer from which the applet was downloaded. If such an entry is present, then the network restriction software permits the network connection between the applet and the content server to be created. If not, the applet may not create a network connection with the content server.
摘要翻译：允许诸如小程序之类的移动代码与网络上的内容服务器建立网络连接，而不将该applet仅限于从其下载的计算机的连接。根据本发明的原理，通过在执行引擎或运行时系统中使用网络限制软件来实现这一点。当小程序尝试创建到内容服务器的网络连接时，网络限制软件检查内容服务器上的名称文件，其名称对应于从其下载小程序的计算机的名称的条目。如果存在这样的条目，则网络限制软件允许创建小应用程序和内容服务器之间的网络连接。如果没有，小程序可能不会与内容服务器建立网络连接。

摘要： A system and methods are disclosed that permit mobile code, such as an applet, to create a network connection with a content server on a network, without exposing the client computer that is running the applet, or other computers with which the client computer may communicate, to a DNS spoofing attack. This is achieved in accordance with the principles of the present invention by using network restriction software in the execution engine or runtime system under which the applet executes. When the applet attempts to create a network connection to a content server, the network restriction software checks a “name directory” on the content server for the presence of an entry whose name corresponds to the name of the computer from which the applet was downloaded. If such an entry is present, then the network restriction software permits the network connection between the applet and the content server to be created. If not, the applet may not create a network connection with the content server. Additionally, address checks may be applied to assist in preventing DNS spoofing attacks from succeeding.

摘要： Persistent data storage for client computer software programs is provided using a repository that enables client computer software programs to store data securely on a client computer system, subsequently retrieve that data, and optionally share the data in a controlled fashion with authorized client computer software programs. The present invention can be used by both trusted and untrusted client computer software programs that either reside locally on the client computer system or are downloaded from a server computer system. A benefit of the present invention is that it allows untrusted applets to have access to persistent storage without compromising the integrity of the client computer system. Since the present invention controls persistent storage space, not the programmer of the client computer software program, the burden of insuring storage integrity and security is removed from the programmer. In addition to basic integrity and security features, the present invention provides automatic data format conversion for client computer software programs reading/writing data in the data repository, a commit operation to force in-memory repository data to disk, and automatic expiration to delete the repository after a predetermined time period. The repository can be pre-limited to a maximum size and shared among multiple client computer software programs.
摘要翻译：使用存储库提供用于客户端计算机软件程序的持久数据存储，其使客户端计算机软件程序能够在客户端计算机系统上安全地存储数据，随后检索该数据，并且可选地以授权的客户端计算机软件程序以受控的方式共享数据。本发明可以由可信任的和不可信的客户端计算机软件程序使用，客户端计算机软件程序本地存在于客户端计算机系统上，或者从服务器计算机系统下载。本发明的优点在于它允许不受信任的小应用程序访问持久存储，而不会影响客户端计算机系统的完整性。由于本发明控制持久存储空间，而不是客户端计算机软件程序的编程者，从程序员中消除了确保存储完整性和安全性的负担。除了基本的完整性和安全性特征之外，本发明还提供了用于在数据存储库中读/写数据的客户端计算机软件程序的自动数据格式转换，强制存储器内存储库数据到磁盘的提交操作，以及自动到期以删除存储库在预定时间段之后。存储库可以预先限制为最大大小，并在多个客户端计算机软件程序之间共享。

摘要： The present invention provides for operations on objects in a hierarchy by partitioning the hierarchy into subhierarchies, each subhierarchy being associated with a thread interface frame. Operations of the thread interface frame are executed within threads acting on objects in the subhierarchy. When needed, the effects of an operation are stored in the thread interface frame, allowing the effects to be forwarded to another subhierarchy accessed by another thread.
