7.2.8.19. SubDispatchFunction

class SubDispatchFunction(dsp, function_id=None, inputs=None, outputs=None, cutoff=None, inputs_dist=None, shrink=True, wildcard=True)[source]

It converts a Dispatcher into a function.

This function takes a sequence of arguments or a key values as input of the dispatch.

Returns:A function that executes the dispatch of the given dsp.
Return type:callable

Example:

A dispatcher with two functions max and min and an unresolved cycle (i.e., a –> max –> c –> min –> a):

Extract a static function node, i.e. the inputs a and b and the output a are fixed:

>>> fun = SubDispatchFunction(dsp, 'myF', ['a', 'b'], ['a'])
>>> fun.__name__
'myF'
>>> fun(b=1, a=2)
0.0

The created function raises a ValueError if un-valid inputs are provided:

>>> fun(1, 0)  # doctest: +IGNORE_EXCEPTION_DETAIL
Traceback (most recent call last):
...
DispatcherError:
  Unreachable output-targets: ...
  Available outputs: ...

Methods

__init__ Initializes the Sub-dispatch Function.
blue Constructs a Blueprint out of the current object.
copy
get_node Returns a sub node of a dispatcher.
plot Plots the Dispatcher with a graph in the DOT language with Graphviz.
web Creates a dispatcher Flask app.
__init__(dsp, function_id=None, inputs=None, outputs=None, cutoff=None, inputs_dist=None, shrink=True, wildcard=True)[source]

Initializes the Sub-dispatch Function.

Parameters:
  • dsp (schedula.Dispatcher) – A dispatcher that identifies the model adopted.
  • function_id (str, optional) – Function name.
  • inputs (list[str], iterable, optional) – Input data nodes.
  • outputs (list[str], iterable, optional) – Ending data nodes.
  • cutoff (float, int, optional) – Depth to stop the search.
  • inputs_dist (dict[str, int | float], optional) – Initial distances of input data nodes.
