## 1. Role

### KKW14301SF03DBean.typeModelData()

This method serves as the **data type provider** for the X33 Framework's type-safe data binding system, implementing the `X33VDataTypeBeanInterface.typeModelData(String, String)` contract. It answers the question "what Java type does this field have?" — the framework uses the returned `Class<?>` to configure column types in data grids and validate bound data at runtime.

The method implements a **routing/dispatch pattern**: it matches the `key` parameter (a business item name) against a fixed set of six recognized fields. For each recognized field, it then matches the `subkey` parameter (`"value"`, `"enable"`, or `"state"`) and returns the corresponding Java class: `String.class` for value and state, `Boolean.class` for the enabled/disabled flag.

This is a **shared utility** consumed by the X33 grid framework during page rendering. The bean is instantiated as the data type provider for the "Discount/Campaign Code List☆Style" (割引／キャンペーンコードリスト☆スタイル) grid item within the KKA35101SF screen (visit order inquiry information search). Every field follows the same three-subkey pattern, making the bean's data model consistent across all grid columns.

The six key branches and their corresponding item IDs (フィールドID) are:

| Key (Japanese) | English Meaning | Item ID (フィールドID) | Value Type | Enable Type | State Type |
|---|---|---|---|---|---|
| コード | Code | `wrib_svc_cd` | `String.class` | `Boolean.class` | `String.class` |
| 名称 | Name | `wrib_svc_nm` | `String.class` | `Boolean.class` | `String.class` |
| 受付開始日 | Service Start Date | `uk_sta_dtm` | `String.class` | `Boolean.class` | `String.class` |
| 受付終了日 | Service End Date | `uk_end_dtm` | `String.class` | `Boolean.class` | `String.class` |
| 適用方法 | Application Method | `aply_way` | `String.class` | `Boolean.class` | `String.class` |
| 割引／キャンペーンコードリスト☆スタイル | Discount/Campaign Code List☆Style | `wrib_svc_cd_list_style` | `String.class` | `Boolean.class` | `String.class` |

If either `key` or `subkey` is `null`, or no matching branch is found, the method returns `null`, signaling to the framework that no data type is defined for the requested item.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The Japanese item name (項目名) of a grid column. Identifies which field's type to resolve. Values: `"コード"` (Code, item ID: `wrib_svc_cd`), `"名称"` (Name, item ID: `wrib_svc_nm`), `"受付開始日"` (Service Start Date, item ID: `uk_sta_dtm`), `"受付終了日"` (Service End Date, item ID: `uk_end_dtm`), `"適用方法"` (Application Method, item ID: `aply_way`), `"割引／キャンペーンコードリスト☆スタイル"` (Discount/Campaign Code List☆Style, item ID: `wrib_svc_cd_list_style`). Affects processing by routing to the corresponding if/else branch. |
| 2 | `subkey` | `String` | The sub-key identifying which aspect of the field's type metadata to return. Values: `"value"` (returns the field's data type — `String.class`), `"enable"` (returns the field's enabled/disabled toggle type — `Boolean.class`), `"state"` (returns the field's state/status type — `String.class`). Case-insensitive comparison via `equalsIgnoreCase()`. Affects which type class is returned. |

**Instance fields read:** None — this method is stateless. It performs no reads of instance fields, relies solely on its two parameters and returns hardcoded `Class<?>` literals.

## 4. CRUD Operations / Called Services

This method performs **no database operations, no service calls, and no I/O**. It is a pure in-memory lookup utility that returns Java `Class<?>` references.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| — | (none) | — | — | Pure type resolution — no database or service interaction |

Method calls within `typeModelData`: None. The method contains only conditional logic and `return` statements with class literals.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0143 (KKA35101SF) | `KKW14301SFBean` -> X33 Framework type provider mechanism -> `KKW14301SF03DBean.typeModelData(key, subkey)` | (none — pure type provider) |

**Notes on caller chain:**
- The bean is declared as the data type provider (`X33VDataTypeBeanInterface` implementation) for the "Discount/Campaign Code List☆Style" repeated grid item (`wrib_svc_cd_list`) in the `KKW14301SFBean` class.
- The X33 Framework invokes `typeModelData(key, subkey)` during grid column configuration to determine Java types for data binding.
- The method is defined in both `koptWebA` and `koptWebB` (copied from koptWebB to koptWebA per revision history).

## 6. Per-Branch Detail Blocks

**Block 1** — IF (null check) `(key == null || subkey == null)` (L527)

> If either parameter is null, return null immediately — prevents NullPointerException and signals "no type defined" to the framework.

| 2 | RETURN | `return null;` |

|---|------|------|
| 1 | SET | `int separaterPoint = key.indexOf("/");` |

**Block 3** — ELSE-IF `"コード"` (Code field) (L531)
