## 1. Role

### JKKIdoRsvHaneiCC.editErrorInfo()

This method is designated as the **error posting process for contract execution** (解約実行のエラー転記処理です。). Its intended business purpose is to map error information onto the `IRequestParameterReadWrite` interface after a service component execution completes (サービスコンポーネント実行後に、IRequestParameterReadWriteにエラー情報をマッピングする). However, the method is currently implemented as a **stub** — the actual mapping logic has been commented out (originally calling `this.mapper.editResultRPEKK0081A010ErrMap(param, templates, returnCode, fixedText)`) and the method unconditionally returns `null`. This method is designed to follow the **delegation pattern**, where it delegates error mapping to a `mapper` object that handles the `EKK0081A010` service component's error result mapping. As a shared utility in the common component layer, it would have been intended as a centralized error-reporting entry point called by CBS or business logic layers after contract cancellation execution completes.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["editErrorInfo(params)"])
    STUB["Return null - method is a stub (actual logic commented out)"]
    END_NODE(["Return null"])

    START --> STUB --> END_NODE
```

**Current state:** The method body contains only a `return null;` statement. The original implementation (commented out) would have performed the following:

1. Invoke `this.mapper.editResultRPEKK0081A010ErrMap(param, templates, returnCode, fixedText)` to map error information to the request parameter object.
2. Return the populated `param` object.

The commented-out code suggests the intended flow was: accept error metadata (templates, return code, fixed text) and route them through a mapper to produce a populated `IRequestParameterReadWrite` response.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `IRequestParameterReadWrite` | Business data read/write interface — the container that carries request/response data between layers. In this context, it serves as the target where error information from the service component will be mapped. |
| 2 | `templates` | `CAANMsg[]` | Array of message templates used for error message construction. Each `CAANMsg` likely contains message codes and text used to populate localized error messages returned to the caller. |
| 3 | `returnCode` | `int` | Return code from the service component execution — indicates success or failure status, used to determine whether error information should be set and which error template to apply. |
| 4 | `fixedText` | `String` | User-defined arbitrary string — additional contextual text that can be embedded into error messages for debugging or audit purposes. |

**External state / instance fields accessed:**
| Field | Type | Description |
|-------|------|-------------|
| `mapper` | (unknown — mapper class) | Instance field referenced as `this.mapper`. Used for mapping error results. Type not visible in this method but is a mapper object with method `editResultRPEKK0081A010ErrMap`. |

## 4. CRUD Operations / Called Services

The method currently performs **no actual operations** — it is a stub that returns `null`. The **intended** (commented-out) behavior would have been:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `mapper.editResultRPEKK0081A010ErrMap` | EKK0081A010 | (unknown) | Map error result information from service component execution onto the request parameter — reads error metadata (templates, return code, fixed text) and populates the `IRequestParameterReadWrite` object with error details. |

No active CRUD operations are performed by the current implementation.

## 5. Dependency Trace

No callers of this method were found across the entire codebase (searched 59,002+ Java files). This is consistent with the method being a stub — it has not been wired into any call chain yet. The method appears to be a planned addition to the contract execution workflow that has not yet been activated.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|

## 6. Per-Branch Detail Blocks

The method body contains no conditional branches, loops, or control flow. The entire method is a single linear path:

**Block 1** — [METHOD BODY] `(no condition)` (L97)

> The method body is a stub. The original implementation that was commented out would have called the mapper to populate error information.

| # | Type | Code |
|---|------|------|
| 1 | COMMENT | `// this.mapper.editResultRPEKK0081A010ErrMap(param, templates, returnCode, fixedText);` // Original: map error results via mapper |
| 2 | COMMENT | `// return param;` // Original: return the populated parameter object |
| 3 | RETURN | `return null;` // Current: stub returning null |
