title: apply formatter only on edited code - eclipse
body: <p>I have implemented a formatter in eclipse for my code, when I try to save the changes it applies formatting on complete file. </p>
  
  <p>Is it possible to apply formatter only on the <strong>changed code</strong> insted of full file?</p>
  
  <p>@Edited</p>
  
  <p>I want to apply this formatter on my existing files on save.
  suppose i have a file with 10 methods and approx 1000 lines. I have added a new method in that file and apply the save. Then I want my formatter to apply formatter only for new added method not for the existing 10 methods.
  I have to do it with each and every file in my project.
  <code>@formatter:off</code> annotation can't help here.</p>
