如何在不使用编辑器的情况下在Eclipse中以编程方式保存文件?

我正在开发一个Eclipse插件,可以通过编程从工作区修改C++文件。我现在正试图保存所做的更改。我看了一下这个解决方案: How can I call save method in eclipse plugin development programmatically 但这包括在编辑器中打开我想要保存的文件。因为我有

我试过使用:

PlatformUI.getWorkbench().getService(IHandlerService.class).executeCommand("org.eclipse.ui.file.saveAll", event)

IWorkspace.save(boolean, IProgressMonitor)

或

ITranslationUnit.save(IProgressMonitor, boolean)

或

ICProject.save(IProgressMonitor, boolean)

因此,我的问题是:

我努力实现的示例

deleteAndSave(IFunction functionToDelete) {
    boolean forceDeletion = true;
    IProgressMonitor progressMonitor = new NullProgressMonitor();
    //delete the portion of code
    functionToDelete.delete(forceDeletion, progressMonitor);
    //we get the file containing the function
    IFile file = (IFile) functionToDelete.getUnderlyingResource();
    //save the file to the disk (ideally 'file.save()' ?)
    file.getWorkspace().save(true, progressMonitor);
}

虽然这不能回答问题(不使用编辑器),但我的行为是正确的:

deleteAndSave(IFunction functionToDelete) {
    IProgressMonitor progressMonitor = new NullProgressMonitor();
    IWorkbenchPage activePage = PlatformUI
        .getWorkbench()
        .getActiveWorkbenchWindow()
        .getActivePage();

    functionToDelete.delete(true, progressMonitor);

    IFile file = (IFile) functionToDelete.getUnderlyingResource();
    IEditorPart editorPart = IDE.openEditor(activePage, file);
    editorPart.doSave(progressMonitor);
    activePage.closeEditor(editorPart, false);
}

但是,这会为每个文件打开一个编辑器页面并立即关闭,因此对于大量文件来说,性能并不令人满意。
