## 1. Role

### KKW01023SF01DBean.loadModelData()

This method is the central data-loading dispatcher for the Discount Service Contract Display screen (`KKW01023SF`), which handles the initial display and inquiry of discount service contracts (割引サービス契約照会) in the K-Opticom customer backbone system. It implements the `X33VDataTypeBeanInterface.loadModelData(String key, String subkey)` contract from the Fujitsu Futurity web framework, serving as the entry point through which the view-layer retrieves field values, enablement flags, and status indicators for screen components.

The method follows a **routing/dispatch pattern**: it receives a `key` (the business field name in Japanese, such as "照会選択" for consultation selection, or "キャンペーンコード" for campaign code) and a `subkey` (the data facet — "value", "enable", or "state"). Based on the `key` value, it routes to the appropriate group of three getter methods that return the field's current value, enabled/disabled state, and input status respectively. This design centralizes all model data access for the screen's data-type beans into a single polymorphic entry point, enabling the X33V framework to dynamically load field data without hard-coding property names in the view templates.

The method supports **8 distinct business fields**: Consultation Selection (照会選択), Number (番号), Campaign Code (キャンペーンコード), Campaign Name (キャンペーン名), Type Code (タイプコード), Type Code Name (タイプコード名称), Category Code (種類コード), and Category Code Name (種類コード名称). For each field, it provides up to 3 sub-key lookups (value/enable/state), yielding up to 23 distinct data retrieval paths. This makes it the foundational data access method for the entire screen's presentation layer.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The Japanese business field name identifying which screen field's data to load. It represents the high-level category of the data item: "照会選択" (Consultation Selection — boolean checkbox for consultation list rows), "番号" (Number — sequential row number), "キャンペーンコード" (Campaign Code — string identifier for the discount campaign), "キャンペーン名" (Campaign Name — human-readable campaign title), "タイプコード" (Type Code — service type classification code), "タイプコード名称" (Type Code Name — descriptive name of the type code), "種類コード" (Category Code — sub-category classification), "種類コード名称" (Category Code Name — descriptive name of the category code). |
| 2 | `subkey` | `String` | The data facet selector within a field, specifying which attribute of the field to return. It is case-insensitive and maps to: "value" (the current data value of the field), "enable" (whether the field is enabled/editable — applies to fields that support toggleable editability), or "state" (the UI state string of the field, used for rendering controls like enabled/disabled styling). |

All 23 method calls are internal getter calls within the same bean — they read instance fields and return their values. These are **pure Read (R)** operations that expose the current state of the bean's data model to the view layer.

**Note:** This method performs exclusively Read (R) operations. It has no C/U/D (Create/Update/Delete) endpoints. The underlying bean instance fields are populated by the `KKW01023SFLogic` business logic class via the `Service.KKSV0231` service invocation (see Section 5 dependency trace), but those population steps occur outside this method's scope.

**Call Chain Details:**
- **KKSV0231** is the "Discount Service Contract Display" screen (割引サービス契約照会画面). The screen's business logic is handled by `KKW01023SFLogic`, which invokes the `KKSV0231` service to fetch discount service contract data and applies it to the `SFBean`. The X33V framework then triggers `loadModelData` on data-type beans (`KKW01023SF01DBean`, `02DBean`, `03DBean`, `04DBean`) to populate individual screen components.
- The `KKW01023SFBean` class serves as the main data bean for the screen and delegates to the `01DBean` through the `X33VDataTypeBeanInterface` contract.
- The method is **not directly called by application code** from other classes — it is invoked exclusively through the X33V framework's data-type bean mechanism, where the framework calls `loadModelData(key, subkey)` for each field during view rendering.

## 6. Per-Branch Detail Blocks

**Block 1** — IF (null guard) `(key == null || subkey == null)` (L343)

Guard against null inputs. If either parameter is null, return null immediately to prevent NPE during subsequent string comparisons.

| 1 | EXEC | `key == null || subkey == null` // null guard check |
| 2 | RETURN | `return null;` // key, subkeyがnullの場合、nullを返す (If key/subkey is null, return null) |

**Block 2** — EXEC (separator point search) (L346)

Computes the position of the "/" separator in the key string. Note: this value is assigned but never used in the current method body (dead code).

| # | Type | Code |
|---|------|------|
| 1 | SET | `int separaterPoint = key.indexOf("/");` // Note: variable is assigned but never used |
