Netbeans API：如何保存当前项目中的文件或所有文件？

Question

I'm developing a plugin module for Netbeans using the provided API in order to provide support for a new programming language.

I've created an Action in the Context Menu, using the MIME-type defined in a File Type.

I looking for a method to save the file that's being selected. Preferably only if it's changed.

Also is it possible to save all the changes in all the files of the project?

Part of my code from the Action Listener class:

    @Override
    public void actionPerformed(ActionEvent ev) {
        FileObject f = context.getPrimaryFile();
        String path = f.getPath();     
        String name = f.getName();

        //Save file here

        ExecutionDescriptor descriptor = new ExecutionDescriptor()
                .controllable(true)
                .frontWindow(true)
                .preExecution(before)
                .postExecution(after);
        ExecutionService exeService = ExecutionService.newService(
                new ProcessLaunch(cmdLine),
                descriptor, "Run " + name);
        Future<Integer> exitCode = exeService.run();

    } 

Answer 1

LifecycleManager.getDefault().saveAll();

这将保存项目中的所有对象。

Answer 2

try this:

FileObject f = ...
DataObject data = DataObject.find(f);
EditorCookie cookie = data.getLookup().lookup(EditorCookie.class);
cookie.saveDocument();
