eclipse中扩展点的添加和删除
ExtensionTracker是IExtensionTracker的实现,用于跟踪插件是否为活动状态,由eclipse官方提供的工具类,eclipse的官方UI组件对IExtensionTracker有自己的实现。如下为例子:
public void removeExtension(IExtension extension, Object[] objects) { // stop using objects associated with // the removed extension for (int i = 0; i < objects.length; ++i) delegates.remove(objects); }?
