Function Class

class Function(name, value=None, parameters=None, action=None)

Purpose

Represent either a constant value or a callable function usable in equations.

Key methods

is_value()

Return whether this function is constant.

Function("pi", value="3.14").is_value()

apply(param_handler=None)

Evaluate through a parameter transformer.

func.apply(lambda parameters: Parameters((
    parameters[0].new(3),
    parameters[1].new(4),
)))

__call__(parameters)

Evaluate with a concrete parameter set.

func(Parameters((
    Parameter("left", value=3),
    Parameter("right", value=4),
)))

Behavior notes

Action-based functions require a declared Parameters layout. Constant-value functions ignore parameter handling completely.
