Solve the following python programming problem given the following code:
def cache(time_to_wait = None, resource_manager = None) : 
    ' cache(time in float seconds) -> decorator

    Given "time" seconds (float), this decorator will cache during that
    time the output of the decorated function. This way, if someone calls
    the cache object with the same input within the next "time" time, the
    function will not be called and the output will be returned instead.
    ' 
    class cache_obj (object) : 
        def __init__(self, func) : 
            super (cache_obj, self).__init__ () 
            self.func = (func,) 
            self.lock = threading.RLock ()
