## 1. Role

### DKW00301SFBean.loadModelData()

This method serves as the central **data access router** for the DKW00301SF (Equipment Return / 返品処理) screen. It implements a **string-based key dispatch** pattern that allows the UI layer to retrieve typed model data from this screen bean using a human-readable key path rather than direct getter calls. The `key` parameter follows a structured path format — for scalar items the path is `"item name/subkey"` (e.g., `"サービス契約番号/value"`), while for list-based data-type beans the path is `"item name/index/propertyName"` (e.g., `"返品抽出条件/0/hmpin_chsht_joken"`).

The method handles **three categories of data**: (1) **Scalar items** — String, Long types such as Service Contract Number, Case Number, Serial Number, Page Number, Screen Mode, and Style, accessed via `value`/`enable`/`state` subkeys; (2) **Data-type bean lists** — repeating groups of complex bean objects including Return Item Search Conditions, Accepting Party, Return Type, Model Numbers, Search Date Choice, Date FROM/TO, Approval Date FROM/TO, Search Results List, Provision Type List, CSV Search Results List, and Selected Search Results List, accessed via index and nested property paths; (3) **String repeatable lists** — Equipment Contract Division Code List and Equipment Contract Division Name List, accessed via index and subkey.

It also serves as a **delegation point** for common-info view data: when the key starts with `"//"`, the method delegates entirely to the parent class's `loadCommonInfoData()` method. This method plays a critical role as a **shared utility** called by 14+ other methods within the same bean class (including `getJsflist_typelist_*` variants) to retrieve screen model data for display, export, and selection purposes.

**Key observation:** Every list-based branch (1–15, 34) and the two string-repeatable branches (24–25) follow an identical structural pattern: (1) extract remainder after first slash, (2) check for `"*"` to return list size, (3) parse index from next segment, (4) validate bounds, (5) delegate to the element's `loadModelData(keyElement, subkey)` or `loadModelData(subkey)`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | Business item path identifying what data to retrieve. For scalar items: `"item name/subkey"` (e.g., `"サービス契約番号/value"`). For list beans: `"item name/index/propertyName"` (e.g., `"返品抽出条件/0/field"`). For common-info views: starts with `"//"` followed by the view key. Can be `null` (returns `null`). |
| 2 | `subkey` | `String` | Sub-property selector. For scalar String items: `"value"`, `"enable"`, or `"state"` to retrieve the data value, editability flag, or screen state respectively. For Long items: `"value"` or `"state"`. For bean list elements: the nested property name to delegate to. Can be `null` (normalized to empty string). |

## 6. Per-Branch Detail Blocks

**Block 1** — [IF] `(key == null)` (L976)

> Guard clause: if the key parameter is null, return null immediately without processing.

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return null;` |

**Block 2** — [ELSE-IF] `(subkey == null)` (L990)

> Null-safe normalization: if subkey is null, replace with an empty string to prevent downstream NPE.

| # | Type | Code |
|---|------|------|
| 1 | SET | `subkey = new String("");` // null-safe normalization |

**Block 3** — [IF] `(separaterPoint == 0)` — Common Info View Check `//` (L998)

> Checks if the key starts with `"//"` (double-slash), which indicates a common-info view data request. If true, delegates to the parent class.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `super.loadCommonInfoData(key);` // delegates common-info retrieval to parent |
| 2 | RETURN | `return ...;` |

**Block 4** — [ELSE] Path Segmentation (L1004–1009)

> For non-common-info keys, extract the first path segment before the first `/` as the `keyElement`. If no slash exists, the entire key becomes the element.

| # | Type | Code |
|---|------|------|
| 1 | SET | `separaterPoint = key.indexOf("/");` // find first slash |
| 2 | IF | `separaterPoint > 0` |
| 3 | SET | `keyElement = key.substring(0, separaterPoint);` // first path segment |
| 4 | ELSE | `keyElement = key;` // no slash; full key is the element |

After extraction, dispatch on `keyElement` via 34 branches. The following blocks detail representative patterns. All list-based branches (Blocks 5–18, 33) follow the identical pattern described in Block 5.

**Block 5** — [IF] `keyElement.equals("返品抽出条件")` — Return Item Search Conditions Bean List (L1012)

> Data-type bean list branch. Supports `"*"` wildcard for list size, index-based element access, and recursive delegation to the element's `loadModelData`.

| # | Type | Code |
|---|------|------|
| 1 | SET | `keyRemain = key.substring(separaterPoint + 1);` // remainder after first slash |
| 2 | IF | `keyRemain.equals("*")` |
| 3 | RETURN | `return Integer.valueOf(i_hmpin_chsht_joken_list.size());` // return list size |
| 4 | SET | `separaterPoint = keyRemain.indexOf("/");` // find second slash |
| 5 | IF | `separaterPoint <= 0` |
| 6 | RETURN | `return null;` // invalid path format |
| 7 | SET | `keyElement = keyRemain.substring(0, separaterPoint);` // parse index string |
| 8 | TRY-CATCH | `tmpIndexInt = Integer.valueOf(keyElement);` // parse index |
| 9 | CATCH | `NumberFormatException e` -> `return null;` // non-numeric index |
| 10 | IF | `tmpIndex < 0 || tmpIndex >= i_hmpin_chsht_joken_list.size()` |
| 11 | RETURN | `return null;` // out-of-bounds index |
| 12 | SET | `keyElement = keyRemain.substring(separaterPoint + 1);` // nested property name |
| 13 | CAST | `(X33VDataTypeBeanInterface)i_hmpin_chsht_joken_list.get(tmpIndex)` |
| 14 | CALL | `element.loadModelData(keyElement, subkey);` // recursive delegation |

**Blocks 6–12** — [ELSE-IF] Identical list-bean branches:

| Block | keyElement | List Field |
|-------|-----------|------------|
| Block 6 | `"受入先"` | `i_ukeire_sk_list` (Accepting Party) |
| Block 7 | `"返品種類"` | `i_hmpin_sbt_list` (Return Type) |
| Block 8 | `"型番号"` | `i_mdl_no_list` (Model Number) |
| Block 9 | `"検索日付選択"` | `i_search_ymd_choice_list` (Search Date Choice) |
| Block 10 | `"日付FROM"` | `i_ymd_sta_list` (Date FROM) |
| Block 11 | `"日付TO"` | `i_ymd_end_list` (Date TO) |
| Block 12 | `"承認日FROM"` | `i_shonin_ymd_sta_list` (Approval Date FROM) |

**Block 13** — [ELSE-IF] `keyElement.equals("承認日TO")` — Approval Date TO Bean List (L1417)

| Block | keyElement | List Field |
|-------|-----------|------------|
| Block 13 | `"承認日TO"` | `i_shonin_ymd_end_list` |
