private static VisitorState getCheckState(VisitorState state) {
 // Gets the VisitorState to start from when checking how to qualify the name. This won't work
 // correctly in all cases 1) it assumes there is only 1 top level type; 2) it doesn't look for
 // all of the locations where the symbol-to-be-replaced is used in the compilation unit.
 // Really, we should gather all of the usages first, and check them all.
 // It is assumed that this will work sufficiently until proven otherwise.

 if (compilationUnit.getTypeDecls().isEmpty()) {
  return state;
 }
 return state.withPath(TreePath.getPath(compilationUnit, compilationUnit.getTypeDecls().get(0)));
