摘要
论述Nutch插件机制的设计目标,分析归纳Nutch轻量级插件体系结构所包括的3组基本概念:微内核、扩展点和扩展;插件、插件清单和插件清单描述器;插件工厂和插件清单解析器。总结Nutch插件的处理流程和概念与实际文件之间的对应关系。对Nutch插件机制的深入理解,有助于灵活构建基于Nutch的新应用。
The design principles of Nuteh＇s plug-in mechanism are discussed. Nutch＇s lightweight plug-in architecture includes three basic concepts. They are micro-kernel ,extension point and extension ;plug-in, plug-in manifest and plug-in manifest descriptor;plug-in factory and plug-in manifest parser. The processes of plug-in and the mappings between relative concepts and real files in Nutch are also summarized. It＇s obvious that in-depth understanding of Nutch＇s plug-in mechanism can contribute to build flexible new applications based on Nutch.
