The relationship between them will be covered in some greater depth after their introductions. <p> The root package (this) contains the executable class <A HREF="../../../org/archive/crawler/Heritrix.html" title="class in org.archive.crawler"><CODE>Heritrix</CODE></A>. That class will load the crawler, parsing command line arguments. If a WUI is to be launched it will launch it. It can also start jobs (with or without the WUI) that are specified in command line options. <h3>framework</h3> <p> <A HREF="../../../org/archive/crawler/framework/package-summary.html"><CODE>org.archive.crawler.framework</CODE></A> <p> The <tt>framework</tt> package contains most of the core classes for running a crawl. It also contains a number of Interfaces for extensible items, the implementatations of whom can be found in other classes. <p> Heritrix is in effect divided into two types of classes. <ol> <li> <em>Core classes</em> - these can often be configured but not replaced. <li> <em>Pluggable classes</em> - these must implment a given interface or extend a specific class but 3rd parties can introduce their own implementations. </ol> The framework thus contains a selection of the core classes and a number of the Interfaces and base classes for the pluggable classes. <h3>datamodel</h3> <p> <A HREF="../../../org/archive/crawler/datamodel/package-summary.html"><CODE>org.archive.crawler.datamodel</CODE></A> <p> Contains various classes that make up the crawlers data structure. Including such essentials as the CandidateURI and CrawlURI classes that wrap the discovered URIs for processing. <h3>admin</h3> <p> <A HREF="../../../org/archive/crawler/admin/package-summary.html"><CODE>org.archive.crawler.admin</CODE></A> <p>⌨️ 快捷键说明
