Backend placeholders

Overview

The backend placeholders are a set of pre-defined classes that can be used as a starting point for building an application. They provide a basic structure and functionality to allow an Algomancy app to launch.

Reference

class algomancy_content.backend.placeholderschema.PlaceholderSchema

Bases: Schema

Schema class to be used as a placeholder

class algomancy_content.backend.placeholderalgorithmtemplate.PlaceholderParams(*args, **kwargs)

Bases: BaseParameterSet

class algomancy_content.backend.placeholderalgorithmtemplate.PlaceholderAlgorithm(params)

Bases: BaseAlgorithm

static initialize_parameters()

Initializes parameters for the derived Algorithm, which is necessary for the GUI logic. It should simply return a default object of the associated AlgorithmParameters class.

Example

>>> @staticmethod
>>> def initialize_parameters() -> ExampleAlgorithmParams:
...    return ExampleAlgorithmParams()

Raises:

NotImplementedError – If the method is not overridden.

Returns:

The initialized set of parameters, derived

from the BaseAlgorithmParameters class.

Return type:

BASE_PARAMS_BOUND

class algomancy_content.backend.placeholderetlfactory.PlaceholderETLFactory

Bases: ETLFactory

class algomancy_content.backend.placeholderkpitemplate.PlaceholderKPI

Bases: BaseKPI

compute(result)

Abstract method to compute the KPI value from scenario results.

Parameters:

result (ScenarioResult) – The scenario result data.

Returns:

The computed numeric value.

Return type:

float
