java – 有没有我可以通过编程方式调用的Eclipse重构API？

Anyone who supports a programming language in an Eclipse-based IDE
will be asked sooner or later to offer automated refactorings –
similar to what is provided by the Java Development Tools (JDT). Since
the release of Eclipse 3.1,at least part of this task (which is by no
means simple) is supported by a language neutral API: the Language
Toolkit (LTK). But how is this API used?

编辑：

如果要在不使用UI的情况下以编程方式运行重构,可以使用RefactoringDescriptors(请参阅article)来填充参数并以编程方式执行重构.如果您创建一个依赖于org.eclipse.core.runtime的插件并添加org.eclipse.core.runtime.applications扩展,您将能够从eclipse运行一个类似于main(String [])类的IApplication类在纯Java应用程序中.可以在post上找到调用API的示例.

ICompilationUnit cu = ... // an ICompilationUnit to rename

RefactoringContribution contribution =
    RefactoringCore.getRefactoringContribution(IJavaRefactorings .RENAME_COMPILATION_UNIT);
RenameJavaElementDescriptor descriptor =
    (RenameJavaElementDescriptor) contribution.createDescriptor();
descriptor.setProject(cu.getResource().getProject().getName( ));
descriptor.setNewName("NewClass"); // new name for a Class
descriptor.setJavaElement(cu);

RefactoringStatus status = new RefactoringStatus();
try {
    Refactoring refactoring = descriptor.createRefactoring(status);

    IProgressMonitor monitor = new NullProgressMonitor();
    refactoring.checkInitialConditions(monitor);
    refactoring.checkFinalConditions(monitor);
    Change change = refactoring.createChange(monitor);
    change.perform(monitor);

} catch (CoreException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

如果您有关于使用JDT API(AST,重构等)的更详细的问题,我建议您在JDT Forum上询问.
