如何在eclipse启动时导入首选项（.epf）？

Question

我正在开发Eclipse插件，它将在启动时导入首选项(.epf)。

@Override
    public void earlyStartup() 
    {       
        Display.getDefault().syncExec( new Runnable() {            


            @Override
            public void run() {
                try {

                     InputStream in = new FileInputStream(new File("D:/pref.epf"));
                       Platform.getPreferencesService ().importPreferences (in);
}
catch (Exception e) {
                    e.printStackTrace ();
                }
            } 
        });
}

查看import preferences对话框，我认为您需要在import中指定一个首选项筛选器：

java prettyprint-override"> IPreferenceFilter [] filters = new IPreferenceFilter[1];

 filters[0] = new IPreferenceFilter() {
     public String[] getScopes() {
       return new String[] {InstanceScope.SCOPE, ConfigurationScope.SCOPE};
     }

     public Map getMapping(String scope) {
       return null;
     }
 };

 IPreferencesService service = Platform.getPreferencesService();

 IExportedPreferences prefs = service.readPreferences(input stream);

 service.applyPreferences(prefs, filters);
