 generator_function

 args
 Positional argument tuple used to 'prime' the ArgumentsGenerator.generator_function.
 
 kwargs
 Keyword argument dictionary used to 'prime' the ArgumentsGenerator.generator_function.

Constructor & Destructor Documentation

◆ __init__()

def __init__ (   self,
  generator_function,
*  args,
**  kwargs 
) 
Simple little class to hold a generator (uninitialised) and the necessary args/kwargs to
initialise it. This lets us re-use a generator by setting it up again fresh. This is not
optimal for expensive calculations, but it is nice for making large sequences of
Job input arguments on the fly.

Parameters:
    generator_function (py:function): A function (callable) that contains a ``yield`` statement. This generator
should *not* be initialised i.e. you haven't called it with ``generator_function(*args, **kwargs)``
yet. That will happen when accessing the `ArgumentsGenerator.generator` property.
    args (tuple): The positional arguments you want to send into the intialisation of the generator.
    kwargs (dict): The keyword arguments you want to send into the intialisation of the generator.

◆ generator()

def generator (   self) 
Returns:
    generator: The initialised generator (using the args and kwargs for initialisation). It should be ready
    to have ``next``/``send`` called on it.
