class Locator(path=None, clean_up=True, copy=True, empty=False, session_ref=None)#

Class representing OneTick database locator. Locator is the file that describes database name, location and other options.

Parameters

  • path (str) – A path to custom locator file. Default is None, that means to generate a temporary locator.

  • clean_up (bool) – If True, then temporary locator will be removed when Locator object will be destroyed. It is helpful for debug purpose. Default is True.

  • copy (bool) – If True, then the passed custom locator by the path parameter will be copied firstly before usage. It might be used when you want to work with a custom locator, but don’t want to change the original file; in that case a custom locator will be copied into a temporary locator and every request for modification will be executed for that temporary locator. Default is True.

  • empty (bool) – If True, then a temporary locator will have no databases, otherwise it will have default otp.config.default_db and COMMON databases. Default is False.
