| Fully Qualified Name | `eo.web.webview.KKA16601SF.KKW00128SF01DBean` |

## 1. Role

### KKW00128SF01DBean.typeModelData()

This method serves as the **central type-routing dispatcher** for the KKA16601SF screen's data bean, which handles the management and display of telecom service contract change orders. In business terms, it acts as a **data type resolver** -- given a field name (key) and a sub-property identifier (subkey), it returns the appropriate Java `Class<?>` type so that the X33 web framework knows how to render, bind, and validate each UI component on the service contract change screen.

The method supports approximately 18 distinct business fields, each representing a piece of service contract data such as system ID, service contract number, movement (transfer/reassignment) classification and reason codes, optional service contract numbers, application numbers, pricing codes, and discount flags. For simple scalar fields, it always returns `String.class` regardless of which subkey (`value` or `state`) is requested. For two list-type fields -- Movement Reason Code (`ido_rsn_cd_list`) and Optional Service Contract Number (`op_svc_kei_no_list`) -- it performs index-based delegation: when the key contains a `"/"` separator followed by an index, it retrieves the corresponding element from the list and delegates type resolution to that element's own `typeModelData` method.

The design pattern used here is a **routing/dispatch pattern with delegation**: the method routes based on the field name (key), then either returns a primitive type directly or delegates to child bean instances for composite (list) data. This is a standard pattern in the X33 framework's data binding architecture, where the UI layer queries the bean for type information to dynamically construct form fields and bind user input. The method plays a critical role in the screen's data model lifecycle, enabling dynamic field rendering without hard-coding field types in the view layer.

The flowchart above shows the high-level architecture. The actual method contains a long if-else-if chain covering all 18 supported fields. Each branch is described in detail in Section 6 below.

The key distinction in the processing pattern is between:
- **Scalar fields** (16 out of 18): These always return `String.class` for both `value` and `state` subkeys. They represent simple text fields on the UI form.
- **List fields** (2 out of 18): These support index-based access via a `"/"`-separated syntax in the key (e.g., `"異動理由コード/0"` for index 0). They can also accept `"*"` as the index portion to return `Integer.class` (representing the list element count). For valid indices, they delegate to the child bean's `typeModelData` method.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The field name (項目名) identifying which screen field's type to resolve. Represents a business data element from the service contract change screen, such as "System ID" (システムID), "Service Contract Number" (サービス契約番号), "Movement Reason Code" (異動理由コード), etc. For list-type fields, the key may contain a `"/"` separator followed by an integer index or the wildcard `"*"` (e.g., `"異動理由コード/0"` or `"オプションサービス契約番号/*"`). |
| 2 | `subkey` | `String` | The sub-property identifier. Typically `"value"` to request the data value's type, or `"state"` to request the UI state's type (e.g., enabled/disabled, visible/hidden status). Case-insensitive comparison. |

**Instance fields read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `ido_rsn_cd_list` | `X33VDataTypeList` | List of movement reason codes (異動理由コード) -- tracks reasons for service line reassignment or transfer. Contains `X33VDataTypeStringBean` elements. |
| `op_svc_kei_no_list` | `X33VDataTypeList` | List of optional service contract numbers (オプションサービス契約番号) -- tracks optional/added services on a contract line. Contains `X33VDataTypeStringBean` elements. |

## 4. CRUD Operations / Called Services

This method is a pure **data type resolver** and does not perform any database CRUD operations directly. It only reads instance fields and delegates to child bean methods for type resolution.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `X33VDataTypeList.get(int)` | X33VDataTypeList | - | Retrieves an element from the movement reason code list by index (ido_rsn_cd_list). Used for index-based access in list-type field branches. |
| - | `X33VDataTypeList.get(int)` | X33VDataTypeList | - | Retrieves an element from the optional service contract number list by index (op_svc_kei_no_list). Used for index-based access in list-type field branches. |
| - | `X33VDataTypeStringBean.typeModelData(String)` | KKW00128SF01DBean | - | Delegates type resolution to a child bean element for composite list fields. Called on individual list elements for the Movement Reason Code and Optional Service Contract Number fields. |

**Note:** The pre-computed evidence lists substring operations from utility classes (`JKKAdEditCC.substring`, `JKKAdEdit.substring`, `JKKTelnoInfoAddMapperCC.substring`, `JDKejbStringEdit.substring`). These appear in the method as `key.substring(separaterPoint + 1)` calls, which are standard Java `String` operations (not the custom utility classes). The method calls `String.substring()` to extract the index portion after the "/" separator in list-type field keys.

## 5. Dependency Trace

This method is called internally by the X33 web framework's data binding mechanism. The framework invokes `typeModelData(key, subkey)` when it needs to determine the Java type of a field during UI rendering, validation, or model loading.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen: KKW00128SF | `X33VViewBaseBean.loadModelProperty(key, subkey)` -> `KKW00128SF01DBean.typeModelData(key, subkey)` | `String.class` / `Integer.class` (return types) |
| 2 | Screen: KKW00128SF | `KKW00128SFBean.getXxx()` -> `KKW00128SF01DBean` instance -> `typeModelData(key, subkey)` | Internal X33 framework method (no external SC/DB call) |

**From this method outward (what it ultimately calls):**

| # | Called Method | Type | Result |
|---|--------------|------|--------|
| 1 | `X33VDataTypeList.get(int index)` | READ (list access) | Retrieves child bean from `ido_rsn_cd_list` or `op_svc_kei_no_list` |
| 2 | `X33VDataTypeStringBean.typeModelData(String subkey)` | Internal | Delegates to child bean's own typeModelData for composite list fields |

**Note:** No external SC (Service Component), CBS (Common Business Service), or database tables are accessed. This method operates entirely within the UI data bean layer, resolving type information from in-memory data structures and Java built-in types.
