Not sure if the intent is that clearCache() should be called, but the
calls have just accidentally been placed after the return statements,
or whether the code works correctly and as intended as it is now,
i.e. with the unreachable calls to clearCache().

Warning emitted by VS 2013, why don't other compilers warn? Perhaps
these functions are never called?
