title: Get method calls of IMethod through eclipse CallHierarchy
body: <p>I am looking to get IMethod, IType or IJavaElement in which a IMethod is being called. I explored org.eclipse.jdt.internal.corext.callhierarchy.CallHierarchy.
  I have written this code but its not giving me anything in wrapper or in location.
  Please guide me.</p>
  
  <pre><code>public void getMethodCallers(IMethod[] methods){
  
  CallHierarchy hierarchy = new CallHierarchy();
  IJavaSearchScope searchScope= SearchEngine.createWorkspaceScope();
  hierarchy.setSearchScope(searchScope);
  CallLocation location = hierarchy.getCallLocation(method[0])
  MethodWrapper [] wrapper = hierarchy.getCalleeRoots(methods);
  
  
  
  }
  </code></pre>
