title: Eclipse plugin: create a treeview that displays all the deprecated methods
body: <p>I'm new to Eclipse plugin development and I'm trying to implement a treeview that displays all the deprecated methods used in the current/selected project.</p>
  
  <p>It should look like this:</p>
  
  <pre><code>-jdom
  --- method1
  -------file1 that uses this method
  -------file2 that uses this method
  --- method2
  -------file1 that uses this method
  --- method3
  -------file1 that uses this method
  -log4j
  ----method1
  -------file1 that uses this method
  --- method2
  --- method3
  </code></pre>
  
  <p>Eclipse has this very good feature that tells you the API that you are using has been deprecated by striking through the <strike>method</strike>.</p>
  
  <p>Is there a way I can get a full list of all the deprecated methods? I'm sure this can be one given what Eclipse can do.</p>
  
  <p>Any explanation on how Eclipse does the strikethrough with reference to the code is also appreciated.</p>
