## 1. Role

### FUW00928SF02DBean.loadModelData()

This method serves as the centralized **data retrieval dispatcher** for the Number Portability (番号ポータビリティ) screen within the K-Opticom fiber optic service ordering system (FUW0092SF). Its business purpose is to provide polymorphic, key-driven access to customer data fields displayed on the number portability UI — enabling the view layer to fetch field values, enabled-state flags, and display-state codes without knowing specific getter method names at compile time. It implements a **routing/dispatch pattern**: the `key` parameter identifies a business field category (e.g., "Display Detail Control Flag", "Number Portability Used Phone Number", "Current Service Provider Name"), while the `subkey` parameter selects the data attribute within that category — `value` for the actual data, `enable` for the field's enabled/disabled state, or `state` for the display status code. The method handles 11 distinct field categories covering display control flags, customer identification data (name, kana name, N-number), number portability data (phone number, current provider, postal code, address), and service selection data (current installation address, current customer name). It plays a central role in the framework's data-binding architecture: the parent `FUW00928SFBean.loadData()` instantiates `FUW00928SF02DBean` objects for each row in the portability list (`bmp_list_list`), then iterates over items calling `loadModelData` to populate the view model with current data. This design supports dynamic screen rendering where field visibility and interactivity are controlled through the framework's data-type bean mechanism (`X33VDataTypeBeanInterface`).

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The business field name (項目名) used as a routing key to select which data category to retrieve. Maps to one of 11 Japanese-labeled field groups displayed on the Number Portability screen, such as "表示詳細制御フラグ" (Display Detail Control Flag), "番号ポータビリティ利用電話番号" (Number Portability Phone Number), "契約者名义" (Contractor Name), etc. Each key triggers a distinct branch handling the getters for that field category. |
| 2 | `subkey` | `String` | The attribute selector within the selected field category. Accepts case-insensitive values: `"value"` to retrieve the field's data value, `"enable"` to retrieve the field's enabled/disabled state flag, or `"state"` to retrieve the field's display status code. Case-insensitive comparison via `equalsIgnoreCase` ensures robustness against inconsistent casing from the caller. |

**Summary:** All 32 method calls within `loadModelData` are **Read (R)** operations. The method exclusively calls getter methods on the same bean (`FUW00928SF02DBean`) to retrieve field values, enabled-state flags, and display-state codes from in-memory instance fields. There are no database, CBS, or external service invocations in this method.

**Notes on caller analysis:**
- `FUW00928SF02DBean` is instantiated as a **data-type bean** (データタイプビューン型) for each row in the "Number Portability List" (番号ポータビリティリスト, item ID: `bmp_list`) within the `FUW00928SFBean` screen controller.
- The `FUW00928SFBean.loadData()` method creates `FUW00928SF02DBean` instances via `addListDataInstance("番号ポータビリティリスト")`, which delegates to the parent class's list management.
- Each `FUW00928SF02DBean` instance receives `loadModelData` calls through the `X33VDataTypeBeanInterface` contract, with `key` values derived from `FUW00928SF02DBean.listKoumokuIds()` (which returns the list of Japanese field names like "表示詳細制御フラグ", "N番号目タイトル", etc.).
- No other screen modules reference `FUW00928SF02DBean.loadModelData` directly — it is scoped to the FUW00928SF (Number Portability) module.
