## 1. Role

### KKW00801SF01DBean.loadModelData()

This method serves as the **centralized property routing engine** for the KKW00801SF screen's data bean. It retrieves values for screen-bound properties using a two-level key system: a **data type key** (e.g., "メールアカウント" — Mail Account, "ウィルスチェック" — Virus Check) and a **sub-key** (e.g., "value", "enable", "state") that determines which aspect of the property to return. This design pattern is a form of **property-based lookup** — similar to a map-based getter that substitutes runtime string resolution for compile-time type safety.

The method handles **14 distinct data types** across three categories. **Category 1 — Static Properties**: Mail account, mail address domain, mail alias, mail box capacity, virus check, POP ID, usage start date (year/month/day), display mail box capacity, display virus check, and registration mail box capacity MB value. Each static property exposes up to three accessor facets: the actual value, an enabled/disabled flag, and a UI state flag. **Category 2 — List-Based Properties**: Mail NOP capacity selection list and virus check selection list. These handle hierarchical key paths in the format "typeName/index/propertyName" (e.g., "プランリスト/0/プラン名" — Plan List/0/Plan Name) and recursively delegate to individual list items.

This method implements the **delegation and template patterns**: it delegates property access to individual getters for static data, and recursively delegates to child data beans for list items. It serves as the **shared utility entry point** for screen rendering — any screen component that needs to read a typed property value calls `loadModelData` with the appropriate key/subkey combination. The fallback path returns null when no matching type or subkey is found, enforcing a safe default behavior.

**Branch Summary:**

| Branch | Condition | Data Types Handled |
|--------|-----------|--------------------|
| Simple (Static) | Key matches a known static data type | Mail Account, Mail Address Domain, Mail Alias, Mail Box Capacity, Virus Check, POP ID, Usage Start Date (Year/Month/Day), Display Mail Box Capacity, Display Virus Check, Registration Mail Box Capacity MB Value |
| List (Mail NOP) | Key equals "メールNOP容量選択リスト" | Mail NOP capacity selection list — recursive delegation to list items |
| List (Virus) | Key equals "ウィルスチェック選択リスト" | Virus check selection list — recursive delegation to list items |

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The **data type identifier** that determines which property group to access. Can be a static type (e.g., "メールアカウント" — Mail Account, "POP ID", "利用開始日（年）" — Usage Start Date Year) or a list type prefix (e.g., "メールNOP容量選択リスト" — Mail NOP Capacity Selection List, "ウィルスチェック選択リスト" — Virus Check Selection List). For list types, the key follows a hierarchical path format: "typeName/index/propertyName" (e.g., "プランリスト/0/プラン名" — Plan List/0/Plan Name), where the portion after the first slash is further parsed to extract an integer index and a nested property key. |
| 2 | `subkey` | `String` | The **accessor facet** specifying which aspect of the property to retrieve. Takes one of three values: `"value"` (the actual data value), `"enable"` (the enabled/disabled flag controlling UI interactivity), or `"state"` (the UI state flag for rendering). Case-insensitive matching (`equalsIgnoreCase`). For list-based keys, the subkey follows the recursive key path and may reference nested property keys on individual list items. |

**Instance fields read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `mlbox_cap_op_list_list` | `List` (of `X33VDataTypeBeanInterface`) | The mail NOP capacity selection list — a collection of selectable capacity options for mail operations |
| `virus_chk_op_list_list` | `List` (of `X33VDataTypeBeanInterface`) | The virus check selection list — a collection of selectable virus check options |

**Analysis:** This method performs **Read-only** operations (R). It does not create, update, or delete any data. All called getters (`getXxx_enabled()`, `getXxx_state()`, `getXxx_value()`) are internal bean property accessors that return pre-loaded screen state data. The `substring` calls are utility string operations (string manipulation on parameter keys). The two list-based branches delegate via `loadModelData` to child `X33VDataTypeBeanInterface` objects, which themselves perform read operations. No database or entity-level CRUD operations originate from this method.

## 5. Dependency Trace

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

No screen/batch entry points found within 8 hops. Direct callers found: 2 methods.
Terminal operations from this method: `loadModelData` [R], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `loadModelData` [R], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-], `substring` [-]

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `KKW00801SF01DBean.getJsflist_typelist_mlbox_cap_op_list()` | `getJsflist_typelist_mlbox_cap_op_list()` → `loadModelData(key, subkey)` | `loadModelData [R]` (recursive to list items) |
| 2 | `KKW00801SF01DBean.getJsflist_typelist_virus_chk_op_list()` | `getJsflist_typelist_virus_chk_op_list()` → `loadModelData(key, subkey)` | `loadModelData [R]` (recursive to list items) |
| 3 | `KKW00801SF01DBean.loadModelData()` (no-arg overload) | `loadModelData()` (no-arg) → `loadModelData(key, subkey)` (parameterized) | `substring [-]`, `getXxx_*() [R]` |

**Trace Notes:**
- The callers are **internal bean accessor methods** within `KKW00801SF01DBean`, not direct screen entry points. They are triggered during screen initialization or property refresh cycles.
- The no-arg overload of `loadModelData()` delegates to the parameterized version, establishing an internal delegation chain.
- No external SC (Service Component) or CBS (Common Business Service) calls are made. No database or entity operations originate from this method — it is purely a **data routing and retrieval** mechanism.
- The recursive calls to `X33VDataTypeBeanInterface.loadModelData()` on list items may reach deeper into the property hierarchy, but remain within the same bean layer.

### Block 14 — ELSE-IF (メールNOP容量選択リスト / Mail NOP Capacity Selection List) (L696)

> データタイプ項目 "メールNOP容量選択リスト" (Item ID: mlbox_cap_op_list)

This block handles **list-type property access** for the mail NOP (Network Operations Platform) capacity selection list. The key follows a hierarchical path format: "プランリスト/0/プラン名" (Plan List/0/Plan Name), where the portion after the first slash is parsed to extract an integer index and a nested property key. This is the first list-based branch and supports recursive property access on individual list items.

#### Block 14.4 — IF (separaterPoint check) (L706)

> 区切り符号が見つからない、または不正の場合は、ここでnullを返す。

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return null` // Return null if no valid separator is found (malformed key path) |

#### Block 14.5 — SET (index string extraction) (L709)

| # | Type | Code |

| 2 | CATCH | `catch (NumberFormatException e)` // Caught when key is not a valid integer string |

#### Block 14.6.1 — CATCH body (null return) (L716)

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return null` // Return null when index parsing fails (invalid format) |

#### Block 14.7 — IF (null check on parsed index) (L718)

#### Block 14.8 — SET (index conversion) (L720)

| # | Type | Code |
|---|------|------|
| 1 | SET | `tmpIndex = tmpIndexInt.intValue()` // Convert Integer to primitive int |

#### Block 14.9 — IF (bounds check) (L722)

> インデックス値がリスト個数-1を超えれば、ここでnullを返す。

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return null` // Return null if tmpIndex is out of bounds (< 0 or >= list size) |

#### Block 14.10 — SET (recursive key extraction) (L726)

> 項目名を生成し、データタイプビューンloadModelDataの値を返す

| # | Type | Code |
|---|------|------|
| 1 | SET | `key = keyRemain.substring(separaterPoint + 1)` // Extract the property key portion after the index (e.g., "プラン名" from "0/プラン名") [-> "/"] |
| 2 | RETURN | `return ((X33VDataTypeBeanInterface) mlbox_cap_op_list_list.get(tmpIndex)).loadModelData(key, subkey)` // Recursively delegate to the list item at the parsed index, passing the remaining key and subkey for property resolution [-> Data Type Bean] |

### Block 16 — ELSE (no matching condition) (L768)
