## 1. Role

### JBSbatKKKojiKnrIfFileLoad.execute()

This method is the main entry point of a batch service that receives and processes **construction-related information reception files** (工事関連情報受信ファイル) from an internal integration interface. It acts as a **file-based dispatcher and router**: it reads a single incoming CSV file (`KKIFI023001_YYYYMMDD.csv`) that contains mixed-type record entries, classifies each record by its 2-character `rec_div` (record division) code, and aggregates data into 14 separate in-memory StringBuilders — one per record type.

The method handles **14 distinct record service categories** through a dispatch pattern: indoor survey results (宅内調査結果情報), design equipment information (設計設備情報), transmission equipment information (伝送設備情報), construction completion information (工事完了情報), construction schedule information for Network and TV, device (terminal) information for Network and TV, construction cancellation information, indoor construction information, construction cost information, STB installation information, and (added in v31.00.00) temporary cancellation receipt and cancellation cancel information.

Each record is parsed as a CSV row, sanitized of quote characters, validated for format, and then routed to the appropriate aggregation method (`setTakchoRsltIf`, `setDsgnEquipInf`, etc.) — a classic **strategy-based dispatch** pattern. After all records are processed, the method writes 14 separate output CSV files, each routed to a distinct file path identified by a unique file ID constant, using the `executeOutputFile` method which delegates to `BufferedWriter` for file I/O.

The method plays a critical role in the **construction information reception pipeline**: it bridges the inbound file from the internal I/F staging directory and the outbound per-type files consumed by downstream processing services (e.g., `JBSbatKKKojiKnrnInfCheck` for validation, and `JBSbatKKKojiKnrnInfToroku` for registration). It is a batch-only, fire-and-forget service invoked as part of the nightly construction information reception workflow. It always returns `null` (a no-op `JBSbatOutputItem`), consistent with batch services that signal completion via file output rather than return values.

**CRUD Summary:** This method performs **file I/O operations only** — no database CRUD. It reads 1 input file (R) and writes 14 output files (C). All intermediate processing occurs in-memory via StringBuilder aggregation. The `executeOutputFile` private method uses `BufferedWriter` with `OutputStreamWriter` (encoding from parent class `ENCODE`) to write data to disk, wrapping any IOException in a `JBSbatBusinessException` with error code `EKKB0250CE`.

**Notes:** This method is not directly invoked by any screen or CBS (no callers were found in the codebase using `new JBSbatKKKojiKnrIfFileLoad` or `.execute()` references). It is a standalone batch service invoked by the batch orchestration framework, consistent with the `JBSbatBusinessService` parent class pattern. The batch runner discovers and executes it as part of the nightly job schedule based on its class naming convention (`JBSbat*` prefix).

## 6. Per-Branch Detail Blocks

**Block 1** — [INITIALIZATION] (L191)

Initialize all in-memory storage for record aggregation.

| # | Type | Code |

| 17 | SET | `data_list = null` // ArrayList for parsed data rows // 「"」を削除したデータを保持 |
| 18 | EXEC | `super.logPrint.printDebugLog("execute_START")` // Start debug log |

**Block 2** — [VARIABLE SETUP] (L220)

Obtain the intermediate file storage directory from common configuration.

| # | Type | Code |
|---|------|------|
| 1 | SET | `free_item = commonItem.getFreeItem()` // Get free item from common item // フリー項目を取得します |
| 2 | SET | `mid_dir_kk = free_item` // Intermediate file storage directory // 中間ファイル格納先 |
| 3 | SET | `naibu_receive_dir_kk = free_item` // Internal I/F storage directory // 内部I/F格納先 |

**Block 3** — [FILE READ] (L226)

Read the input CSV file. The file path is constructed as `{free_item}/{KKIFI023001}_{YYYYMMDD}.csv`.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `file_data_list = getInputFile(naibu_receive_dir_kk + KOJI_KNRN_INF_RCV_FILE_ID + "_" + super.opeDate + FILE_KEISHIKI)` // Read construction-related information reception file // 工事関連情報受信ファイル読み込み |

**Block 4** — [FOR LOOP: iterate all rows] (L229)

Outer loop: iterate over each row of the input file.

| # | Type | Code |
|---|------|------|
| 1 | SET | `i = 0` // Loop counter // for (int i = 0; ...) |
| 2 | COND | `i < file_data_list.size()` // Process all rows // 工事関連情報受信ファイル件数の繰り返し |
| 3 | SET | `data_work = file_data_list.get(i)` // Get 1-line data // 1行目を取得 |

**Block 4.1** — [ROW PARSING] (L234)

Parse the CSV row: split by comma and strip quote characters.

|---|------|------|
| 1 | SET | `data = data_work.split(",", -1)` // Split data by comma // データを分解 |
| 2 | SET | `data_list = new ArrayList<String>(data.length)` // Store data without quotes // 「"」を削除したデータを保持 |

**Block 4.1.1** — [FOR LOOP: strip quotes] (L239)

Inner loop: iterate over each field and remove quote characters.

| # | Type | Code |
|---|------|------|
| 1 | SET | `j = 0` // Inner loop counter |
| 2 | COND | `j < data.length` // Process all fields |
| 3 | EXEC | `data_list.add(data[j].replaceAll("\"", ""))` // Remove `"` character // ["]を削除 |

**Block 4.2** — [NULL CHECK on rec_div] (L247)

Check if the first field (`rec_div`) is null. If null, skip this row.

| # | Type | Code |
|---|------|------|
| 1 | COND | `null != data_list.get(0)` // rec_div is not null // レコード区分の取得 |
