| Field | Value |
|-------|-------|
| Fully Qualified Name | `eo.web.webview.CRW03407SF.CRW03407SF03DBean` |
| Layer | Controller (webview / Presentation Bean — implements X33V framework interfaces `X33VDataTypeBeanInterface`, `X33VListedBeanInterface`) |
| Module | `CRW03407SF` (Package: `eo.web.webview.CRW03407SF`) |

## 1. Role

### CRW03407SF03DBean.typeModelData()

This method serves as the X33V framework's type-resolution callback for the CRW03407SF screen's data-binding layer. The X33V framework (Fujitsu's web client generation tool) calls `typeModelData` at runtime to determine the Java data type of each UI-bound field before it renders or validates input. The method implements a **routing/dispatch pattern**: it receives a `key` (the Japanese field label) and a `subkey` (the metadata property name), then returns the appropriate `Class<?>` — either `String.class`, `Boolean.class`, or `null` when the field is not configured.

Six distinct UI field categories are handled, each corresponding to a detail-grid column definition on the screen. For the first four fields (Detail Index, Campaign Code, Campaign Name, Applicable Month), the method supports three subkey variants: `value` (the field's data value as String), `enable` (whether the field is editable as Boolean), and `state` (a status/state string). The last two fields (Row Style Class, Row Style ID) are read-only styling properties and only support `value` and `state` subkeys — no `enable` subkey.

If either parameter is `null`, or if the `key` does not match any of the six registered field labels, the method returns `null`, signaling to the X33V framework that the field should be skipped. This method performs **no CRUD operations**, no external service calls, and no side effects — it is a pure, stateless type-dispatch lookup.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The Japanese field label of the data binding field on the X33V screen. Determines which of the six registered field categories the type lookup should resolve. Valid values: `明細インデックス` (Detail Index, internal grid row identifier), `キャンペーンコード` (Campaign Code, the service campaign identifier displayed as `l2_dsp_campaign_cd`), `キャンペーン名` (Campaign Name, the service campaign name displayed as `l2_wrib_svc_nm`), `適用月` (Applicable Month, the service term start month displayed as `l2_wrib_svc_tstaymd`), `行スタイルクラス` (Row Style Class, CSS class for row styling displayed as `l2_line_style_class`), `行スタイルID` (Row Style ID, CSS ID for row styling displayed as `l2_line_style_id`). Also accepts a slash-separated format like `key/index` for indexed field access. |
| 2 | `subkey` | `String` | The metadata property name within the matched field category. For most fields, valid values are `value` (returns the data type for the field's primary data, i.e. `String.class`), `enable` (returns the data type for the field's enabled/disabled state, i.e. `Boolean.class`), or `state` (returns the data type for the field's state/status, i.e. `String.class`). For the two row-styling fields (`行スタイルクラス`, `行スタイルID`), only `value` and `state` subkeys are supported — no `enable` variant. |

**Instance fields read by this method:** None. The method is purely stateless — it performs string comparisons and returns `Class<?>` objects without accessing any instance fields.

## 4. CRUD Operations / Called Services

This method performs **no CRUD operations**. It does not call any Service Components (SC), Call Back Services (CBS), DAOs, or database layer methods. It is a pure, read-only type-dispatch utility with no side effects.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| *(none)* | — | — | — | This method is a stateless type lookup with no data access. |

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:CCW00203SF | `CCW00203SFBean.typeModelData(gamenId, key, subkey)` -> `typeModelData(key, subkey)` -> `CRW03407SF03DBean.typeModelData` | *(none — pure type lookup)* |

**Note:** This method is a framework callback invoked by the X33V framework infrastructure at runtime. The only direct code-level caller found is `CCW00203SFBean`, which provides a three-argument overload (`gamenId`, `key`, `subkey`) that delegates to the two-argument `typeModelData(key, subkey)` method. The `gamenId` parameter is unused (marked as `予備` / "reserved" in Javadoc). It is expected that the X33V view framework also invokes this method directly via reflection or interface dispatch during screen initialization and data-binding resolution.

## 6. Per-Branch Detail Blocks

**Block 1** — IF (null check) `(key == null || subkey == null)` (L493)

> Returns null if either parameter is null — early guard against invalid calls.

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return null;` // key or subkey is null, return null (key,subkeyがnullの場合、nullを返す) [L494] |

**Block 2** — EXEC (separator check) `key.indexOf("/")` (L496)

> Computes the position of the '/' separator in the key for slash-separated field identification format. The result is stored in `separaterPoint` but the variable is not used within this method's scope — the slash logic is documented in the parent class javadoc for the framework contract.

| # | Type | Code |
|---|------|------|
| 1 | SET | `int separaterPoint = key.indexOf("/");` // locate slash separator in key [L496] |

**Block 3** — IF-ELSE chain (key routing) (L500–L567)

> Core dispatch logic: branches on the Japanese field label to determine the data type mapping. Each top-level IF/ELSE-IF checks a specific key.

**Block 3.5** — ELSE-IF [key equals `行スタイルクラス` (Row Style Class)] (L540)

> Matches the row style CSS class field, displayed as the internal field `l2_line_style_class`. Used to apply CSS styling classes to detail grid rows. **No `enable` subkey** — rows are styled but not directly toggled.
