  def handle_entity(self, entity):
    """Subclasses can override this to add custom entity conversion code.

    This is called for each entity, after its properties are populated
    from the input but before it is stored. Subclasses can override
    this to add custom entity handling code.

    The entity to be inserted should be returned. If multiple entities
    should be inserted, return a list of entities. If no entities
    should be inserted, return None or [].

    Args:

    Returns:

    return entity
