API Reference

Purpose

This section provides technical specifications for all features of RDEToolKit. It is a comprehensive reference including detailed functionality, parameters, return values, and usage examples for each module.

API Documentation Structure

RDEToolKit's API documentation is structured using a hybrid approach:

• Auto-generated parts: Detailed technical specifications generated from docstrings in source code
• Manually created parts: Practical usage examples and inter-module collaboration methods

Core Modules

Workflow Management

• workflows - Structured processing execution and workflow management
• modeproc - Mode processing

Configuration and File Operations

• config - Configuration file loading and management
• fileops - RDE-related file operations

Data Processing

• invoicefile - Invoice file processing
• validation - Data validation
• rde2util - RDE-related utility functions
• csv2graph - CSV visualization and plotting pipeline

Representative Image Operations

• img2thumb - Image to thumbnail conversion

Error Handling and Logging

• rdelogger - Logging functionality
• errors - Error handling
• exceptions - Exception handling

Data Models

Configuration Models

• models.config - Configuration data structure definitions

RDE-related Models

• models.rde2types - RDE-related type definitions
• models.invoice - Invoice data structure
• models.metadata - Metadata management

Processing Result Models

• Processing result management functionality is integrated into each module

Implementation Modules

Controllers

• impl.input_controller - Input mode management
• impl.compressed_controller - Compressed file management

Interfaces

• interface.filechecker - File validation interface

Command Line

• CLI Commands - Command line interface usage

import rdetoolkit
from rdetoolkit.models.rde2types import RdeDatasetPaths


def my_dataset_function(paths: RdeDatasetPaths) -> None:
    # Implement custom processing here
    pass


# Execute structured processing
result = rdetoolkit.workflows.run(custom_dataset_function=my_dataset_function)

Legacy callbacks that accept RdeInputDirPaths and RdeOutputResourcePath as two separate arguments continue to work during the compatibility period. Accessors such as paths.invoice, paths.invoice_org, and paths.metadata_def_json mirror the most commonly used paths.
