To do this requires a robust mechanism for declaring and loading plug-ins 这需要稳健的机制来声明和下载插件。
When loaded plug-ins are grouped, the row s values are for the plug-in and all its child plug-ins 当加载的插件被分组的时候,行的值对应于插件以及它所有子插件。
Eclipse has a deferred load strategy to avoid loading plug-ins until the user does something that requires their code eclipse有一个延迟装入的策略,以在用户执行需要插件代码的操作时才装入插件。
Recall that the goal is to avoid loading plug-ins until they are needed, so references to the plug-ins themselves are by : explicitly stated identifiers such as 不要忘记,我们的目的是,不到插件被用到的时候尽量不去加载它,所以对插件本身的引用这样实现:
