# Business Logic — JBSbatKKCourseChgFileBnkt.terminal() [7 LOC]

| Field | Value |
|-------|-------|
| Fully Qualified Name | `eo.business.service.JBSbatKKCourseChgFileBnkt` |
| Layer | Batch Service (extends `JBSbatBusinessService`) |
| Module | `service` (Package: `eo.business.service`) |

## 1. Role

### JBSbatKKCourseChgFileBnkt.terminal()

This method represents the **business service termination processing** (業務サービス終了処理) hook within the `JBSbatKKCourseChgFileBnkt` batch component. The class itself is the **Course Change File Division Part** (コース変更ファイル分割部品) of the eO Customer Base System (eo顧客基幹システム), responsible for splitting course change files in a batch processing pipeline. The `terminal()` method serves as the lifecycle exit point in the batch service pattern — it is called after the main `execute()` processing completes (and regardless of success or failure), giving the batch framework a chance to perform any necessary cleanup or finalization. Currently, this method body is a **template-generated stub** — the developer placeholders indicate where custom termination logic should be written, but no implementation code has been added. The method declares `throws Exception`, allowing termination logic to propagate errors to the batch framework.

## 2. Processing Pattern (Detailed Business Logic)

    START(["terminal()"])
    START --> NOP["No-Op: Template-generated stub — no executable code"]
    NOP --> END_NODE(["Return / Next"])
```

**Block description:** The method body contains only placeholder comments (`/**▽▽▽▽▽▽業務サービスの終了処理を記述してください。▽▽▽▽▽▽` — "Please write business service termination processing here") and generated stub markers. There are **zero executable statements** in this method. The batch framework will call this as the final lifecycle step after `initial()` and `execute()`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | — This method takes no parameters. It operates on instance fields set during the `initial()` phase of the batch lifecycle. |

**Instance fields read (by parent class or convention):**

| No | Field Name | Type | Business Description |
|----|-----------|------|---------------------|
| 1 | `in_file_path` | `String` | Input file path for the pre-split course change file (分割元ファイルパス) |
| 2 | `kj_fin_file_path` | `String` | Work completion file path — marker file written when work finishes normally (工事完了ファイルパス) |
| 3 | `kj_fin_cl_file_path` | `String` | Work completion cancellation file path — marker for cancelled completions (工事完了取消ファイルパス) |
| 4 | `kj_cl_file_path` | `String` | Work cancellation file path — marker for cancelled work (工事取消ファイルパス) |

## 4. CRUD Operations / Called Services

This method contains **no executable code** and therefore performs **no CRUD operations** and calls **no services or CBS components**.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| — | — | — | — | No operations — template-generated stub |

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: `JBSbatKKCourseChgFileBnkt` | `JBSbatBusinessService.run()` (framework) -> `JBSbatKKCourseChgFileBnkt.terminal` | none |

**Notes:**
- The `terminal()` method is called by the batch framework (`JBSbatBusinessService`) as part of the standard batch lifecycle: `initial()` -> `execute()` -> `terminal()`.
- No other classes or screens reference this method directly in the codebase.
- The caller search found no explicit references to `JBSbatKKCourseChgFileBnkt.terminal()` outside of its own class definition.

## 6. Per-Branch Detail Blocks

**Block 1** — [METHOD BODY] `(public void terminal() throws Exception)` (L266)

> No executable code. This is a template-generated stub. The Javadoc reads: 業務サービス終了処理 (Business Service Termination Processing).
