如何在XText中访问当前打开的文件的位置

Question

I am supposed to read the currently open DSL File to create an Auto Populate Feature. For that I am supposed to find the location of the file programmatically and then read it. However there seems to be no alternatives for this purpose. If I use Eclipse Plugin Methods, I get the following error java.lang.ClassCastException: org.eclipse.xtext.xbase.ui.editor.XbaseEditor cannot be cast to org.eclipse.core.resources.IFile Please Help

The standard way to determine the file that any editor is editing is:

IEditorPart editor = get the editor

IEditorInput editorInput = editor.getEditorInput();

if (editorInput instanceof IFileEditorInput)
 {
   IFile file = ((IFileEditorInput)editorInput).getFile();

   // TODO handle file
 }
