## 1. Role

### KKW01031SF02DBean.loadModelData()

This method is the **central data-access router** for a web-screen detail bean (DBean) in K-Opticom's FTTH (Fiber To The Home) subscription management application. It implements the X33V framework's `X33VDataTypeBeanInterface` contract, enabling UI components to dynamically request individual field attributes — value, editability (`enable`), and display state (`state`) — by specifying a **field label** (`key`) and an **attribute name** (`subkey`). The method uses a Japanese-language display label as the lookup key (e.g., `"番号／件数"` for "Number / Record Count", `"契約種別"` for "Contract Type") and maps it to the corresponding internal field via a long chain of if/else-if branches.

It implements the **routing/dispatch pattern**: each of the 13 key branches handles a distinct business field, and within each branch, the subkey determines whether the returned attribute is the current data value, the enabled/disabled flag, or the read-only state. Fields with `enable` support (e.g., `no_cnt`, `campaign_nm`, `stat_nm`, `type_cd_nm`, `aply_jun_nm`, `staymd`, `endymd`) expose 3 subkey branches (value/enable/state), while simpler fields expose only 2 (value/state).

The method is called exclusively by the parent screen bean `KKW01031SFBean` during model initialization (`loadModelData` delegation and `getListDataInstance` key inspection). It performs **no external calls** — all data is read from the bean's own protected instance fields, making it a pure in-memory data accessor. This method plays the role of a **presentation-tier data facade**, decoupling UI components from the internal field names by using human-readable Japanese labels as the query interface.

**Processing Summary:**

The method executes a hierarchical dispatch:

1. **Null Guard (L486–490):** Immediately returns `null` if either `key` or `subkey` is null (Japanese comment: "key, subkey が null の場合、null を返す" — "If key/subkey is null, return null").
2. **Separator Scan (L492):** Scans `key` for a `/` character into `separaterPoint`. This variable is **declared but never used** — likely leftover from a prior routing variant that split composite keys.
3. **Field Routing (L495–L645):** A cascade of 13 if/else-if branches, each comparing `key` against a **literal Japanese display label**. Within each branch, the `subkey` (case-insensitive via `equalsIgnoreCase`) determines which attribute getter is invoked:
   - **3-attribute fields** (value/enable/state): `no_cnt` (番号／件数), `campaign_nm` (キャンペーン名称), `stat_nm` (ステータス名称), `type_cd_nm` (タイプコード名称), `aply_jun_nm` (即時適用フラグ名称), `staymd` (開始年月日), `endymd` (終了年月日)
   - **2-attribute fields** (value/state only): `no` (番号), `kei_kind` (契約種別), `upd_dtm_bf` (更新年月日時分秒更新前), `stat` (ステータス), `type_cd` (タイプコード), `aply_jun` (即時適用フラグ)
4. **Fallback (L647):** Returns `null` if no key matches.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The **Japanese display label** of a form field whose data is being requested. Acts as the primary routing key — each unique value selects a different business data category (e.g., "番号／件数" selects the record count field, "契約種別" selects the contract type). Can contain a slash (`/`) for composite labels, though the separator is not currently used in routing. |
| 2 | `subkey` | `String` | The **attribute name** to retrieve for the specified field. Determines whether to return the data `value`, the `enable` flag (editability control), or the `state` (read-only/visual state). Values are case-insensitive. Not all fields support the `enable` attribute — only fields with a dedicated `*_enabled` instance field do. |

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

This method performs **pure in-memory reads** — no database, no CBS, no SC calls. All operations delegate to the bean's own getter methods on its instance fields.

|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKW01031SF | `KKW01031SFBean.loadModelData` -> `KKW01031SF02DBean.loadModelData` | in-memory getter delegates (see Section 4) |
| 2 | Screen:KKW01031SF | `KKW01031SFBean.listKoumokuIds` -> `KKW01031SF02DBean.listKoumokuIds` (related) | in-memory field access |

**Caller Details:**

- **KKW01031SFBean.java (L1146):** Calls `KKW01031SF02DBean.listKoumokuIds()` (a sibling method that returns a list of all field key identifiers for the "キャンペーン一覧" / Campaign List display-type bean). This is a **sibling call**, not a call to `loadModelData` itself, but demonstrates the same delegation pattern.
- **KKW01031SFBean.java (L1218):** Creates `KKW01031SF02DBean tmpBean = new KKW01031SF02DBean()` for data-type bean-type instantiation, confirming the bean is used as a child bean for composite/dynamic data fields.

The `loadModelData` method is part of the **X33V framework's data-loading lifecycle**. In this framework, screen beans call `loadModelData()` to populate the view state. The detail bean (`KKW01031SF02DBean`) receives dynamic queries from the framework or parent bean for individual field attributes.
