#uses_routine(routine_class, options = {}) ⇒ Object

Called at a routine’s class level to foretell which other routines will be used when this routine executes. Helpful for figuring out ahead of time what kind of transaction isolation level should be used.

Raises:

  • (Lev.configuration.illegal_argument_error)
