Validation helper for feature importance management.

This module provides the FeatureImportanceValidationHelper class with static methods for validating feature importance inputs, analyses, and dependencies. Extracted from FeatureImportanceManager to improve code organization and testability.

class mdxplain.feature_importance.helper.feature_importance_validation_helper.FeatureImportanceValidationHelper

Static helper class for feature importance validation operations.

Provides validation methods for analysis names, analyzer types, comparisons, and dependencies. All methods are static and stateless.

static validate_analysis_name(pipeline_data: PipelineData, analysis_name: str, force: bool) → None

Validate analysis name doesn’t already exist unless force is used.

Parameters

pipeline_dataPipelineData: Pipeline data object containing existing analyses
analysis_namestr: Name of the analysis to validate
forcebool: Whether to allow overwriting existing analysis

Returns

None: Method returns nothing, raises ValueError if name exists and force=False

Raises

ValueError: If analysis name already exists and force=False

static validate_analysis_exists(pipeline_data: PipelineData, analysis_name: str) → None

Validate that feature importance analysis with given name exists.

Parameters

pipeline_dataPipelineData: Pipeline data object containing analysis data
analysis_namestr: Name of the analysis to validate

Returns

None: Method returns nothing, raises ValueError if analysis not found

Raises

ValueError: If analysis not found in pipeline_data

static validate_comparison_exists(pipeline_data: PipelineData, comparison_name: str) → None

Validate that comparison with given name exists.

Parameters

pipeline_dataPipelineData: Pipeline data object containing comparison data
comparison_namestr: Name of the comparison to validate

Returns

None: Method returns nothing, raises ValueError if comparison not found

Raises

ValueError: If comparison not found in pipeline_data
