1、Eclipse重构功能：扩展点的使用 Eclipse中提供了几个扩展点，方便扩展重构功能。   基本的重构功能有，   Rename，Move，Create，Delete，Copy.对应扩展点即为：org.eclipse.ltk.core.refactoring.renameParticipantsorg.eclipse.ltk.core.refactoring.moveParticipantsorg.eclipse.ltk.core.refactoring.createParticipantsorg.eclipse.ltk.core.refactoring.delet

2、eParticipantsorg.eclipse.ltk.core.refactoring.copyParticipants   以ReName为例，其余4项与ReName大同小异。   实现这个扩展点的基本语法：

3、TypeParticipant"   class="jp.co.intramart.app.producer.refactoring.TypeRenameParticipant">         这里默认对响应所有改名事件，如果需要过滤可以在元素中加以定义。不赘述。实现改名扩展的关键在实现类，必须是org.eclipse.ltk.core.refactoring.participants.RenameParticipant；的子类

4、   下面代码进行了简单的Eclipse重构功能实现。importorg.eclipse.core.resources.IFile;importorg.eclipse.core.resources.ResourcesPlugin;importorg.eclipse.core.runtime.CoreException;importorg.eclipse.core.runtime.IProgressMonitor;importorg.eclipse.core.runtime.OperationCanceledException;importorg.eclipse.ltk.

5、core.refactoring.Change;importorg.eclipse.ltk.core.refactoring.RefactoringStatus;importorg.eclipse.ltk.core.refactoring.TextFileChange;importorg.eclipse.ltk.core.refactoring.participants.CheckConditionsContext;importorg.eclipse.ltk.core.refactoring.participants.RenameParticipant;importor

6、g.eclipse.text.edits.ReplaceEdit;publicclassTypeRenameParticipantextendsRenameParticipant{   publicTypeRenameParticipant(){   }   @Override   publicRefactoringStatuscheckConditions(IProgressMonitorpm,           CheckConditionsContextcontext)throwsOperationCanceledException{       returnn

7、ewRefactoringStatus();   }   @Override   publicChangecreateChange(IProgressMonitorpm)throwsCoreException,           OperationCanceledException{       IFilefile=ResourcesPlugin.getWorkspace().getRoot().getProject("a")               .getFile("a");       TextFileChangetextFi
