## 1. Role

### KKW22101SF02DBean.loadModelData()

This method serves as the central data-dispatch entry point for the `KKW22101SF02DBean` class, which models **equipment provision service contract details** in the telecom service contract management domain. When a screen needs to populate or inspect a field within an equipment provision service contract row, it calls `loadModelData` with a human-readable **item name** (key) and a **subkey** that selects which aspect of that field to retrieve — its current value, its enabled/disabled state, or its visual state (e.g., displayed, hidden).

The method implements a **routing/dispatch pattern** based on two parameters: the business field identifier (a Japanese-labeled item name like "宅内機器型式コード" — Indoor Equipment Model Code) and the subkey selector ("value", "enable", or "state"). For each of the six supported field types, the method delegates to one of three accessor methods, effectively providing a uniform interface to all bean properties.

This is a **shared view-model utility** called by the screen's repeating-item framework (`X33VDataTypeList`) when iterating over equipment provision service contract detail rows. It enables screens to dynamically query any property of a `KKW22101SF02DBean` instance without knowing the specific getter method at compile time — the key/subkey convention is defined by the screen's item configuration, making the bean reusable across multiple display contexts.

The six supported branches cover the complete set of editable/displayable fields for an equipment provision service contract: indoor equipment model code, indoor equipment model name, equipment order request start year/month, equipment plan start date, equipment provision service name, and SmartLink Premium subscription status. If the key does not match any known field, the method returns `null`.

**Processing overview:**

1. **Null guard (L289)**: If either `key` or `subkey` is `null`, return `null` immediately.
2. **Separator scan (L291)**: Search for `'/'` in the `key` string (the result is stored in `separaterPoint` but is not used in this method — likely a vestige of a prior routing scheme that used `"key/subkey"` delimited strings).
3. **Field dispatch chain (L294–L374)**: A cascading if/else-if chain checks the `key` value against six known Japanese item names. For each matching field, a nested if/else-if chain checks the `subkey` (case-insensitive) to determine which property to return:
   - `"value"` → the field's current data value
   - `"enable"` → the field's enabled/disabled flag (from the `xxx_enabled` instance field)
   - `"state"` → the field's UI state (from the `xxx_state` instance field)
4. **Fallback (L376)**: If no key matches, return `null`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The **business item name** — a human-readable Japanese label identifying which field on the equipment provision service contract detail to query. Examples: "宅内機器型式コード" (Indoor Equipment Model Code), "機器提供サービス名" (Equipment Provision Service Name). The key determines which of the six field branches the method enters. |
| 2 | `subkey` | `String` | The **property selector** — specifies which aspect of the identified field to return. Valid values (case-insensitive): `"value"` (the field's current data value), `"enable"` (whether the field is editable/enabled in the UI), `"state"` (the field's display state, e.g., visible/hidden). |

| 1 | Screen:KKW22101SF (KKW22101SFBean) | `KKW22101SFBean.setListData("機器提供サービス契約一覧明细リスト", ...)` → instantiates `KKW22101SF02DBean` → framework calls `KKW22101SF02DBean.loadModelData(key, subkey)` via `X33VDataTypeBeanInterface` | `getTaknkiki_model_cd_value [R] in-memory`, `getTaknkiki_model_cd_enabled [R] in-memory`, `getTaknkiki_model_cd_state [R] in-memory`, `getTaknkiki_model_nm_value [R] in-memory`, `getKiki_kap_seiky_sta_ym_value [R] in-memory`, `getKiki_kap_seiky_sta_ym_enabled [R] in-memory`, `getKiki_kap_seiky_sta_ym_state [R] in-memory`, `getKiki_pplan_sta_ym_value [R] in-memory`, `getKiki_tk_svs_mei_value [R] in-memory`, `getSmartrink_premium_um_value [R] in-memory` |
| 2 | Screen:KKW22101SF (KKW22101SFBean) | `KKW22101SFBean.setListData("機器提供サービス契約一覧明细リスト", ...)` → instantiates `KKW22101SF02DBean` → framework calls `loadModelData` for `service_list` repeating items | Same as above — all 18 internal getters |

**Caller details:**

The method is invoked by the `KKW22101SFBean` screen bean (in `KKW22101SFBean.java`, around line 4255) during the `setListData` flow. When the framework encounters a data-type-bean item type for the item key `"機器提供サービス契約一覧明细リスト"` (Equipment Provision Service Contract Detail List), it instantiates `KKW22101SF02DBean` objects and delegates property access to them through the `X33VDataTypeBeanInterface`. The `loadModelData` method is thus the primary data-loading hook for equipment provision service contract row fields.
