# Com / Optage / Kopt / Batch

## Overview

The `com.optage.kopt.batch` package is a minimal stub module containing auto-generated fixture classes used for SPEC-SCOPED-WIKI tests. Each class acts as a placeholder entry point for batch processing scenarios, providing a `run()` method that serves as a test hook.

## Key Classes and Interfaces

### KKPRC14901

A fixture class representing the primary batch processing step. It provides two methods:

- **`check()`** — A no-op stub intended as a pre-run validation hook. Currently has no implementation.
- **`run()`** — The main execution entry point. When invoked, it delegates to a new instance of `EKK0301A010` from the `com.optage.kopt.ekk` package and calls its `process()` method. This is the only class in the package with an actual dependency beyond the stub body.

### KKPRC24901

A fixture class representing the secondary batch processing step. It provides a single `run()` method that currently has no body beyond a comment marker. This appears to be a placeholder for a batch step that is planned or may be populated by a different test scenario.

### KKPRC34901

A fixture class representing the tertiary batch processing step. Like `KKPRC24901`, it exposes a single `run()` method with no implementation. The naming convention (14901, 24901, 34901) suggests these classes follow a systematic naming scheme tied to their position in a batch pipeline.

## How It Works

Each class follows the same pattern:

1. A `run()` method is the primary entry point, invoked by the test harness or a batch scheduler.
2. `KKPRC14901.run()` creates an `EKK0301A010` instance and calls `process()` on it, delegating the actual work to that class in the `com.optage.kopt.ekk` package.
3. `check()` on `KKPRC14901` serves as a pre-flight check hook, though it is currently unimplemented.

The three classes likely correspond to sequential or alternative batch steps in a test-driven workflow. The suffixes (`14901`, `24901`, `34901`) encode the step ordering.

## Dependencies and Integration

This package depends on `com.optage.kopt.ekk`, specifically the `EKK0301A010` class, which `KKPRC14901` delegates to in its `run()` method.

## Notes for Developers

- These classes are **auto-generated fixture classes** for SPEC-SCOPED-WIKI tests. They are scaffolding and not intended for direct production use.
- The classes follow a strict naming convention: `KKPRC` prefix with a numeric suffix that encodes processing order (1xx for primary, 2xx for secondary, 3xx for tertiary).
- `KKPRC14901` is the only class with a non-trivial implementation (`run()` delegates to `EKK0301A010.process()`). The other two classes are empty stubs awaiting implementation or test population.
- `check()` on `KKPRC14901` is a no-op stub. If pre-run validation logic is needed, this is the place to add it.
- No child subpackages or additional classes exist in this module.
