# Business Logic — KKW00127SF02DBean.typeModelData() [157 LOC]

| Field | Value |
|-------|-------|
| Fully Qualified Name | `eo.web.webview.KKW00127SF.KKW00127SF02DBean` |
| Layer | View/Screen Data Bean (Futurity X33 web framework) |
| Module | `KKW00127SF` (Package: `eo.web.webview.KKW00127SF`) |

## 1. Role

### KKW00127SF02DBean.typeModelData()

This method serves as a **runtime type introspection router** for the `KKW00127SF02DBean` screen data bean, implementing a key-value based dispatch pattern. Given a business item name (`key`) and a sub-key (`subkey`), it returns the appropriate `Class<?>` type that describes the data model for that field. This enables the Futurity X33 view framework to perform dynamic type checking, data binding, and validation on the server side without hardcoding type information in templates.

The method handles two distinct categories of fields: **scalar (primitive) fields** such as service contract status, application detail number, payment method continuation flag, and auto-inquiry processing status code — all of which resolve to `String.class` when the `subkey` is `"value"` or `"state"`. It also handles **list (repeating) fields** — specifically the service contract status list (`svc_kei_stat_lis_list`) and introduction code list (`intr_cd_list_list`) — which resolve to `Integer.class` when the subkey is `"*"` (requesting the list element count), or delegate to the child bean's own `typeModelData()` method when a specific index and subkey are provided.

This is a shared utility within the bean's data model, not a screen entry point. It is called by the X33 view framework during page rendering, form validation, and AJAX partial updates to determine whether a given field is a String, Integer, or a nested list item.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The Japanese-language business item name. This identifies which field of the bean the caller is asking about — e.g., "サービス契約ステータス" (Service Contract Status), "申込明細番号" (Application Detail Number), "料金グループコード" (Price Group Code), "紹介コードリスト" (Introduction Code List). For list-type fields, the key follows the pattern `"LIST_KEY/index"` where the index is appended after a slash. |
| 2 | `subkey` | `String` | A sub-attribute selector within a field. For scalar fields it accepts `"value"` (to get the data type of the field's value) or `"state"` (to get the data type of the field's UI state). For list fields it is forwarded to the child `X33VDataTypeStringBean.typeModelData()` method. |

**Instance fields read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `svc_kei_stat_lis_list` | `X33VDataTypeList` | The repeating list of service contract status items. Used when the key is "サービス契約ステータスリスト" (Service Contract Status List). |
| `intr_cd_list_list` | `X33VDataTypeList` | The repeating list of introduction/referred-by codes. Used when the key is "紹介コードリスト" (Introduction Code List). |

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `X33VDataTypeStringBean.typeModelData` | X33VDataTypeBean | - | Delegates to child bean's type model method for list elements (scalar or list item introspection) |
| - | `String.indexOf` | Java Lang | - | Finds the `/` separator position in the key string for list index extraction |
| - | `String.substring` | Java Lang | - | Extracts the index portion after the `/` separator |
| - | `Integer.valueOf` | Java Lang | - | Parses the extracted index string to an integer |
| - | `X33VDataTypeList.size` | X33VDataTypeList | - | Gets the count of elements in the list for bounds checking |
| - | `X33VDataTypeList.get` | X33VDataTypeList | - | Retrieves a specific list element by index |

This method performs **no direct database or SC/CBS operations**. It is a pure type-resolution utility that operates entirely in-memory on bean fields.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Internal Bean Framework | `X33VView framework calls typeModelData` | `X33VDataTypeStringBean.typeModelData [R] in-memory list element` |

**Note:** The pre-computed caller analysis shows that `typeModelData` is called internally within `KKW00127SF02DBean`. This method implements the `X33VDataTypeBeanInterface` contract, meaning the Futurity X33 view framework calls it automatically during page rendering and validation to resolve data types at runtime. No external screens or batches invoke it directly.

## 6. Per-Branch Detail Blocks

### Block 1 — IF (null guard) `(key == null || subkey == null)` (L730)

Null-check guard: returns null immediately if either argument is null.

| # | Type | Code |
|---|------|------|
| 1 | SET | `separaterPoint = key.indexOf("/")` // L732: Find first slash for list key parsing |

### Block 2 — IF-ELSE-IF chain (key dispatch) (L735–L867)

Top-level dispatch on the `key` value. Each branch handles one business item type.

### Block 2.1 — IF `key.equals("サービス契約ステータス")` (Service Contract Status) (L735)

| 2 | RETURN | `return String.class` // L737: The value type is String |
| 3 | ELSE-IF | `subkey.equalsIgnoreCase("state")` // L739: subkey is "state" (case-insensitive). Comment: subkeyが"state"の場合、ステータスを返す。 |
