Get mapped object based on Alias string?

Hi,

I am trying to create a python function that allows me to find a mapped object based on the MappedName string. Here is my function currently:

def wait_for_mapping_object_to_exist(mapping):
  attempt = 1
  while attempt <= retry:
    try:
      reference_object = None
      reference_object = Aliases.Find("MappedName", mapping, str(mapping).count(".") + 2)
      if not reference_object.Exists:
        raise Exception("Object not detected.")
      return reference_object
    except Exception as e:
      Log.Message(str(e))
      delay_with_retries(1000, "Unable to find object. Waiting for timeout.")
      attempt = attempt + 1
  return None

While doing a "Find" search works well, simply setting a variable to a NameMapping object seems to be the fastest way normally. for example:

reference_object = Aliases.javaw.MainWindow

However, I would like to perform this given the string name of the Alias. That would allow me to pass the alias as a parameter without throwing an error that the parameter does not exist. Ideally, something that looks like this:

def get_mapping_object(alias_str):
  # example: alias_str is equal to a string of "Aliases.javaw.MainWindow"
  reference_object = someLibrary.getMappedObjectFromString(alias_str)
  return reference_object

Is there a built in library for doing this? Would it potentially save me time over a "Find" search? Thanks
