## 1. Role

### KKW01601SF02DBean.typeModelData()

This method implements a **data type routing/dispatch pattern** for the K-Opticom web application's data binding framework. It maps **billing contract history** (請求契約履歴) field names and sub-keys to their corresponding Java runtime types (`String.class`, `Boolean.class`), enabling the framework to perform compile-time-safe property access on bean instances at runtime.

The method handles fields across multiple business domains within the **billing and contract history** context: payment review results, payment methods (bank transfer, credit card), financial institution details (bank name, branch code), card information (card number, expiry, card type), customer information (postal code, address components, phone number, department, responsible person name), invoice-related flags, audit timestamps, authorization records, and mask/flags for display fields.

It implements a **delegation pattern** through a long `if-else if` chain (approximately 70+ key conditions), where each key represents a specific business field name in Japanese. Each key branch further dispatches on the `subkey` parameter to distinguish between `value` (the actual data value), `enable` (editability flag), and `state` (UI state). This pattern is consistent with the X31/X33 web framework's data binding contract where `typeModelData` serves as a reflection-free alternative to Java's `Class` introspection.

The method is a **shared utility** called by the parent bean's `typeModelData` dispatcher (KKW01601SFBean) to resolve field types for the "billing contract history" list items, and is indirectly invoked by multiple screens: KKSV0381, KKSV0384, KKSV0403, KKSV0405, KKSV0406, and KKSV1057 through their respective OPDBMapper mapping classes. It plays no CRUD role — it is purely a **type resolution utility** with zero side effects.

**Processing Summary:**

1. **Null Guard** — If either `key` or `subkey` is `null`, return `null` immediately.
2. **Separator Index Computation** — Compute `separaterPoint = key.indexOf('/')`. (Note: the result is never used — this appears to be a vestigial computation.)
3. **Key Dispatch** — A chain of ~70 `else if(key.equals("JapaneseFieldName"))` conditions matches the input `key` against known field names. Each key corresponds to a specific business field listed in the KKW01601SFConst constant class.
4. **Sub-key Dispatch** — Within each matched key block, a nested `if-else if` chain dispatches on `subkey`:
   - `value` (case-insensitive) → `String.class`
   - `enable` (case-insensitive) → `Boolean.class`
   - `state` (case-insensitive) → `String.class`
5. **Notable sub-key patterns**: Some fields (e.g., "支払い方法コード", "請求書発行要否コード") have only `value` and `state` sub-keys (no `enable`). The "選択" (selection) field additionally supports `enable` with `Boolean.class`.
6. **Fallback** — If no key matches, return `null`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | Field name in Japanese — the business identifier of a billing/contract-history data item. Examples: "選択" (Selection), "請求契約番号" (Billing Contract Number), "支払い審査結果" (Payment Review Result), "口座番号" (Account Number), "クレジットカード" (Credit Card). Each `key` maps to a specific field in the billing contract history entity. |
| 2 | `subkey` | `String` | Sub-key identifying which property facet of the field to resolve: `value` (the data value itself), `enable` (whether the field is editable), or `state` (the UI state/status). Case-insensitive comparison. |

**Instance fields or external state read:** None. This method is entirely stateless — it does not read any instance fields, static variables, or external resources. It is a pure function of its two parameters.

## 4. CRUD Operations / Called Services

This method performs **no CRUD operations** and **calls no services**. It is a pure type-mapping utility with zero side effects. No database reads, writes, updates, or deletes occur.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |

| 7 | Parent Bean | `KKW01601SFBean.typeModelData(key, subkey)` directly delegates to `KKW01601SF02DBean.typeModelData(key, subkey)` | N/A (no CRUD) |

**Call pattern detail:** The `KKW01601SFBean` (parent container) contains a `typeModelData(String key, String subkey)` method that internally creates instances of `KKW01601SF02DBean` for the "billing contract history" list items, and delegates type resolution by calling `KKW01601SF02DBean.typeModelData` as a static utility or on the created instance. The `KKW01601SFBean.typeModelData(String key, String subkey)` method (at line 26314) is the direct delegator.

The `KKW01601SF02DBean` also has a duplicate copy at `source/koptWebB/...` mirroring the same implementation for the WebB build variant.
