OBJECT TECHNOLOGY FRAMEWORK SOFTWARE DEVELOPMENT

对象技术框架(OTF)包括我们的后续工作 关于处理分子数据的类库。OTF是 使用面向对象的范例来设计和实现 将功能组织为模块内的组件，并 可扩展框架。可以通过组合来创建应用程序 选择具有少量定制代码的预制组件， 使开发新的分析工具变得容易得多。OTF有 已在本地用于开发生成理想化的应用程序 胶原蛋白模型，计算蛋白质中的二面角，以及计算 蛋白质中氨基酸的高斯邻接值。所有这些都是 应用程序在很短的时间内实现，大部分时间都花在了 设计和编码特定于应用程序的算法。改进之处 在编码效率方面源于预制件的使用 OTF的组件和组织工具。新版本的 OTF在#年通过匿名ftp在互联网上提供 1996年11月。此最新版本包括重新设计的 组件层次结构以及用于管理这些组件的新程序 组件。与我们的所有软件一样，OTF分发为 有记录的源代码。OTF的最新文档也是 自1997年12月起，可通过万维网获得，网址为 Http://cgl.ucsf.edu/home/otf.

The Object Technology Framework (OTF) includes our continued work on class libraries for manipulating molecular data. The OTF is designed and implemented using an object-oriented paradigm that organizes the functionality into components within a modular and extensible framework. Applications can be created by combining selected prefabricated components with a small amount of custom code, making development of new analysis tools much easier. The OTF has been used locally to develop applications for generating idealized collagen models, computing dihedral angles in proteins, and computing Gaussian neighborhood values of amino acids in proteins. All these applications were implemented in a short time, most of which was spent designing and coding application-specific algorithms. The improvement in coding efficiency stems from the use of the prefabricated components and the organization tools of the OTF. A new release of the OTF was made available on the Internet via anonymous ftp in November, 1996. This latest release includes a redesign of the component hierarchy as well as a new program for managing these components. As with all of our software, the OTF is distributed as documented source code. Up-to-date documentation of the OTF is also available, as of December 1997, via the World Wide Web at http://cgl.ucsf.edu/home/otf.
