 // SequenceChecker is a helper class used to help verify that some
 // methods of a class are called in sequence -- that is, called from
 // the same SequencedTaskRunner. It is a generalization of
 // ThreadChecker; see comments in sequence_checker_impl.h for details.
 //
 // Example:
 // class MyClass {
 //  public:
 //   void Foo() {
-//     DCHECK(sequence_checker_.CalledOnValidSequence());
+//     DCHECK(sequence_checker_.CalledOnValidSequencedThread());
 //     ... (do stuff) ...
 //   }
 //
 //  private:
 //   SequenceChecker sequence_checker_;
 // }
 //
 // In Release mode, CalledOnValidSequence will always return true.
