Instance Method Details

#before ⇒ Object

NOTE: Dependencies don’t use Rudy::Routines.add_handler but we define them ehere anyway so raise_early_exceptions passes.

Rudy::Routines.add_handler :before,  self

#execute(routine_name) ⇒ Object

A simple wrapper for executing a routine.

  • routine_name should be a Symbol representing a routine available to the current machine group.

This method finds the handler for the given routine, creates an instance, calls raise_early_exceptions, and finally executes the routine.

def execute(routine_name)
  routine_obj = Rudy::Routines.get_routine routine_name
  ld "Executing dependency: #{routine_name} (#{routine_obj})"
  routine = routine_obj.new routine_name
  routine.raise_early_exceptions
  routine.execute
end

#execute_all(depends) ⇒ Object

Calls execute for each routine name in depends (an Array). Does nothing if given an empty Array or nil.
