## 1. Role

### KKW00801SF03DBean.loadModelData()

This method implements the core data-access dispatcher for the `KKW00801SF03DBean` data bean, which represents the "Virus Check Yes/No List" (ウィルスチェック有無リスト) item in the service contract management screen KKW00801SF. It receives a `key` (field/item identifier in Japanese) and a `subkey` (property accessor type: `value`, `enable`, or `state`), then routes the request to the appropriate getter method. This is a classic routing/dispatch pattern — the method acts as a polymorphic data bridge between the screen's generic data-binding infrastructure (which calls `loadModelData` dynamically) and the 12 domain-specific fields managed by this bean.

The method handles 12 distinct field categories: code type code, code type name, code type description, code classification, code classification name, code classification alias, code effective start date, code effective end date, display order, initial display code, initial display code name, and update timestamp. Each category supports three subkey variants: retrieving the actual data value, checking the enabled/disabled state, and reading the display state. This pattern allows the X33V data bean framework to access any field's data, enable flag, or state flag through a single unified entry point, enabling generic list-item rendering and form-binding without compile-time knowledge of individual field names.

The method implements the `X33VDataTypeBeanInterface.loadModelData()` contract, meaning it is called by the framework whenever a data-type view component (a list item or form field) needs to resolve its value dynamically. It plays the role of a shared utility within the `KKW00801SF` module, specifically serving the "Virus Check" virus-check management screen area where code-related metadata fields are displayed and edited.

**Block Summary:**

| Step | Description |
|------|-------------|
| 1 | Null guard: if `key` or `subkey` is null, return null immediately (L504-L507) |
| 2 | Compute `sep = key.indexOf("/")` — parses potential compound key format (L509) |
| 3-14 | 12 parallel if/else-if branches matching `key` to field categories (L512-L659) |
| 15 | Nested subkey branches: each field category has 3 cases — `value` (actual data), `enable` (enabled/disabled flag), `state` (display state) (L514-L657) |
| 16 | Fallback: if no key matches, return null (L661-L662) |

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | Field/item identifier in Japanese — selects which of the 12 data bean fields to access. Valid values are Japanese field names: コード種類コード (code type code), コード種類名 (code type name), コード種類説明 (code type description), コード区分 (code classification), コード区分名 (code classification name), コード区分略称 (code classification alias), コード適用開始年月日 (code effective start date), コード適用終了年月日 (code effective end date), 表示順序 (display order), 初期表示コード (initial display code), 初期表示コード名称 (initial display code name), 更新年月日時刻 (update timestamp). Determines which data branch to dispatch into. |
| 2 | `subkey` | `String` | Property accessor type — selects the metadata property to read from the matched field. Valid values (case-insensitive): `value` (returns the actual data value), `enable` (returns the enabled/disabled state — whether the field is active in the UI), `state` (returns the display state — e.g., read-only, required, or input type). |

**Instance fields read by this method:**
- All 12 field accessor properties (value, enable, state getters) — each returns a value from the bean's internal state. The actual backing fields (`cd_sbt_cd_value`, `cd_sbt_cd_enabled`, `cd_sbt_cd_state`, `cd_sbt_nm_value`, `cd_sbt_nm_enabled`, `cd_sbt_nm_state`, `cd_sbt_setmei_value`, `cd_sbt_setmei_enabled`, `cd_sbt_setmei_state`, `cd_div_value`, `cd_div_enabled`, `cd_div_state`, `cd_div_nm_value`, `cd_div_nm_enabled`, `cd_div_nm_state`, `cd_div_ali_value`, `cd_div_ali_enabled`, `cd_div_ali_state`, `cd_tstaymd_value`, `cd_tstaymd_enabled`, `cd_tstaymd_state`, `cd_tendymd_value`, `cd_tendymd_enabled`, `cd_tendymd_state`, `dsp_jun_value`, `dsp_jun_enabled`, `dsp_jun_state`, `shk_dsp_cd_value`, `shk_dsp_cd_enabled`, `shk_dsp_cd_state`, `shk_dsp_cd_nm_value`, `shk_dsp_cd_nm_enabled`, `shk_dsp_cd_nm_state`, `upd_dtm_value`, `upd_dtm_enabled`, `upd_dtm_state`) are read via their getter methods.

**Analysis:** This method performs **only Read (R)** operations. It is a pure getter/router — no Create, Update, or Delete operations occur. The method delegates to 36 local getter methods (12 fields x 3 subkeys each) that simply return values from the bean's internal fields. No SC (Service Component), CBS (Common Business Service), or database access is performed. The data originates from the bean's own state, which was populated earlier by a CBS layer during the screen's data loading phase.

|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKW00801SF (KKW00801SFBean) | `KKW00801SFBean.addListDataInstance` -> creates `KKW00801SF03DBean` -> framework calls `loadModelData(key, subkey)` | `getCd_sbt_cd_value [R] bean field` |

**Additional callers in other screens (cross-screen pattern):**

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 4 | Screen:FUW00912SF (FUW00912SFBean) | `FUW00912SFBean` iterates over `svc_kb_dates_list` / `btns_list` (X33VDataTypeBeanInterface) -> calls `loadModelData(key, subkey)` on each | `getXxx [R] bean field` |
| 5 | Screen:FUW00926SF (FUW00926SFBean) | `FUW00926SFBean` iterates over `use_bmp_list_list` / `tv_stb_info_list_list` -> calls `loadModelData` via dynamic key routing | `getXxx [R] bean field` |

| 7 | Screen:FUW00964SF (FUW00964SFBean) | `FUW00964SFBean` iterates over `svc_gaiyo_info_list`, `vdsl_prc_info_list`, etc. -> calls `loadModelData` | `getXxx [R] bean field` |

The method is called via the `X33VDataTypeBeanInterface` contract, meaning any screen that uses `KKW00801SF03DBean` as a data-type bean (list item type) will invoke `loadModelData` through the framework's generic data-binding mechanism. The callers found are all screens (class names containing `KKSV` or `FUW` patterns) that use the X33V data bean framework.

## 6. Per-Branch Detail Blocks

### Block 1 — IF (null guard) (L504-L507)

Null check: if either `key` or `subkey` is null, return null immediately. This prevents NullPointerException and acts as a guard clause for invalid framework invocations.

| # | Type | Code |
|---|------|------|
| 1 | IF | `if (key == null || subkey == null)` // key or subkey is null — returns null immediately |
| 2 | RETURN | `return null;` // returns null |

### Block 2 — Processing Step: Separator Extraction (L509)

Computes the index of "/" in `key` for potential compound key parsing. Note: the `separaterPoint` variable is computed but never used in any subsequent branch — it appears to be reserved for future extensibility.

| # | Type | Code |
|---|------|------|
| 1 | SET | `int separaterPoint = key.indexOf("/");` // extracts separator position (currently unused) |

### Block 3 — IF/ELSE-IF: Key Routing (コード種類コード) (L512-L528)

> data type is String field "Code Type Code" (item ID: cd_sbt_cd)

Handles routing for the code type code field. The `key` is compared against the Japanese string literal `コード種類コード` (Code Type Code).

#### Block 3.1 — IF/ELSE-IF/ELSE-IF: Subkey Routing (value) (L514-L516)

| # | Type | Code |
|---|------|------|
| 1 | IF | `if (subkey.equalsIgnoreCase("value"))` // case-insensitive match for "value" |
