摘要： The present invention creates a model that maps object classes in an object-oriented environment to a data source. The model maps the relationship between properties of each object class and data of the data source. The present invention can be used with a data source such as a relational database, user interface, file system, or object-oriented database. An application's object classes and data source schema are designed independent of the other since the model can be used to map one to the other. The model is comprised of entities and attributes. An entity maps to an object class and to at least one table of the DBMS. An entity contains attributes either simple or derived. A simple attribute maps to a DBMS column. A derived attribute is a combination of other attributes and does not directly map to a DBMS column. A relationship creates a link between entities of the model. A relationship can be used to flatten an attribute or flatten a relationship. A flattened attribute is an attribute of one entity that is added to another entity. A flattened relationship is created by the elimination of intermediate relationships between two entities. Relationships can be either unidirectional or bi-directional. A unidirectional relationship has a single traversal path that has a source entity and a destination. A bi-directional relationship has two traversal paths. A reflexive relationship can be created using a single entity. The model is used to synchronize object properties and the data of the data source.

摘要： The present invention discloses a system for transparent local and distributed memory management. The invention overcomes the prior art's requirement of keeping track of whether a memory space allocated to a new object or a new program or data structure can be reclaimed. According to the present invention an autorelease pool is created at the beginning of a new duty cycle. The autorelease pool retains the newly allocated memory space during the duty cycle. The autorelease pool is automatically disposed of at the end of the duty cycle. As a result of disposing the autorelease pool the newly allocated memory space is reclaimed (i.e., deallocated). The present invention is useful in distributed networks where different programming conventions on remote and local machines made the prior art's memory management task particularly difficult. The present invention is also useful in an object-oriented programming environment.
摘要翻译：本发明公开了一种用于透明的本地和分布式存储器管理的系统。本发明克服了现有技术跟踪分配给新对象或新程序或数据结构的存储空间是否可以回收的要求。根据本发明，在新的占空比开始时创建自动释放池。自动释放池在占空比期间保留新分配的内存空间。自动释放池在占空比结束时自动处理。作为处理自动释放池的结果，新分配的存储空间被回收（即，被释放）。本发明在分布式网络中是有用的，其中远程和本地机器上的不同编程约定使现有技术的存储器管理任务变得特别困难。本发明在面向对象编程环境中也是有用的。

摘要： The present invention dynamically brokers object messages between object models. An mediating component provides a bridge between object models such that messages can be transmitted in either direction between object models. The mediating component can be resident on a client machine, a server machine, or both. The mediating component can be used as a bridge between two instances of the same object model running on different machines. Thus, network communication is made possible for objects of an object model that otherwise lacks a networking capability. The mediating component maps a client object to a server object through proxy objects and stub objects. The proxy object always responds affirmatively when queried by a client object whether a server object can execute a particular method. A client object's message is forwarded to a server object. The mediating component performs any necessary translation of arguments or format of the message. In addition, the mediating component translates a server object's response.

摘要： The present invention comprises a novel system for managing changes to a graph of data bearing objects. In one embodiment, an object graph manager object referred to as an editing context is used to identify changes made to data bearing enterprise objects and to notify other interested objects when changes occur. As a result, data bearing objects need not themselves contain code necessary for monitoring changes. In another embodiment of the invention, the editing context is used to provide event-based “undo” capabilities. In another embodiment of the invention, each enterprise object has a primary key that is used to maintain the identification between an enterprise object instance and a corresponding database row. In another embodiment of the invention, multiple levels of editing contexts are used to provide multiple isolated object graphs, each of which allows independent manipulation of the underlying data bearing objects.

摘要： In the present invention, HTML elements are mapped to objects in an object-oriented environment. Classes of objects are defined for each HTML element as well as the HTML document (or page). By providing a one-to-one mapping between each HTML element and object classes, HTML documents can be manipulated programmatically. The properties of each element are stored in instance variables of the associated object. Each object class can include methods to manipulate the HTML element within an HTML document.

摘要： The object-oriented approach used by the present invention provides the ability to develop and manage Internet transactions. Local applications can be accessed using any workstation connected to the Internet regardless of the workstation's configuration. Some or all of a Web page can be generated dynamically using input received in a returned page, generated at runtime, or retrieved from an external data source (e.g., database or electronic mail system). When the Web page definition is rendered, the information contained in template(s), declaration file(s), and object(s) are used to generate standard definitions. State information is maintained across transactions. Using state information, virtual applications, sessions, transactions, and pages can be implemented. Self-contained modules, or components, provide the ability to share implementations and create multi-content documents. Event objects can be used to assist in event handling management.

摘要： The present invention improves speed and reduces complexity in a digital signature scheme that uses elliptic algebra. The signature scheme generates two points that are compared. If the points do not match, the signature is not authentic. The present invention reduces computations by comparing only the x coordinates of the two generated points. The invention provides a scheme for deducing the possible values of the x-coordinate of a sum of two points using only the x coordinates of the original two points in question. The present invention provides a scheme that limits the possible solutions that satisfy the equation to two (the authentic signature and one other). Because of the large number of possible inauthentic solutions, the chance of a false authentic signature is statistically insignificant.

摘要： The present invention is a method that enables single release of applications for multiple architectures and operating systems and to provide ease of use of applications in multiple architecture environments. The present invention provides a single file that contains separate object code each of multiple architectures. A special header on the file identifies each section of object code and includes pointers to its starting location. When the file is to be executed on a particular architecture, the resident operating system identifies that block of object code most suited for that particular architecture and environment. That section of code is then loaded into memory for execution. Each architecture in the file is specified by CPU-type and CPU sub-type. For each CPU type or CPU sub-type, file offset, file size and alignment is also provided. Padded bytes are provided to place each member on its specific alignment. These padded bytes are undefined and can be left as "holes" if the file system cannot support them. The appropriate architecture can be picked at compile time and compilers that can run on any architecture are provided to perform the translation.
