## 1. Role

### KKW01037SFBean.loadModelData()

This method serves as the central data access gateway for the KKW01037SF screen's view model, implementing a hierarchical key-based routing and dispatch pattern. It retrieves data values and status flags from the bean's internal state by parsing a structured `key` string that identifies the target field, service type category, or list element. The method handles eight distinct business data categories: system identifier (継続システムID), customer service category (継続お客様情報), referral contract party name (紹介者契約者名), referral phone number (紹介者電話番号), referral system identifier (紹介者システムID), service contract full list (サービス契約一覧リスト), customer contract succession list (顧客契約引継リスト), and popup mode (ポップアップモード). For scalar fields it routes to specific getter methods that return either the value, enabled state, or display status depending on the `subkey` parameter. For list-based fields it supports wildcard queries (e.g., index `*`) to return list sizes, and fully delegated indexed lookups that route through to individual list element beans implementing `X33VDataTypeBeanInterface`. This design follows the **routing/dispatch pattern** combined with **delegation**, where the parent bean acts as a facade that forwards requests to subordinate data beans, making it a shared utility called by many screen methods to achieve loose coupling between the view layer and the data model.

```

This method acts as a **centralized routing gateway** that parses a key string and dispatches the request to the appropriate data retrieval handler.

**Phase 1 — Input Validation and Normalization**
The method first checks if `key` is `null` and returns `null` immediately if so. If `subkey` is `null`, it is normalized to an empty string to prevent downstream `null` checks.

**Phase 2 — Common Info Detection**
The method checks if `key` starts with the `//` separator (indicating a common-info view item). If `separaterPoint == 0`, the request is delegated entirely to the parent class's `loadCommonInfoData(key)` method, which handles shared informational display data.

**Phase 3 — Key Element Extraction**
For non-common-info keys, the method locates the first `/` separator. If found (position > 0), the first element before the `/` is extracted as `keyElement` (e.g., from `"サービス契約一覧リスト/0/planName"` the keyElement is `"サービス契約一覧リスト"`). If no separator is found, the entire key is treated as the keyElement for scalar fields.

**Phase 4 — Type-Based Dispatch**
The method branches into 8 type-specific handlers:

1. **継続システムID** (HKTG_SYSID) — Returns the system ID value or state based on subkey.
2. **継続お客様情報** (HKTG_SVC_KEI_NO) — Returns the customer service category value or state.
3. **紹介者契約者名** (HI_CUST_NM) — Returns the referral contract party name value, enabled flag, or state.
4. **紹介者電話番号** (HI_TELNO) — Returns the referral phone number value, enabled flag, or state.
5. **紹介者システムID** (HI_SYSID) — Returns the referral system ID value, enabled flag, or state.
6. **サービス契約一覧リスト** (SVC_KEI_LIST) — A hierarchical list type supporting index-based delegation to child beans.
7. **顧客契約引継リスト** (CUST_KEI_HKTGI_LIST) — A hierarchical list type with the same structure as the service list.
8. **ポップアップモード** (POPUP_MODE) — Returns the popup mode value or state.

**Phase 5 — List Type Handling**
For list-based types (Items 6 and 7), the method parses the remaining key path to extract an array index (as a numeric string) and delegates to the specific list element's `loadModelData` method. If the index is `*`, it returns the list size. Index validation catches `NumberFormatException` and out-of-bounds access.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | A hierarchical field identifier that routes to specific data categories. For scalar fields, it contains the Japanese field name (e.g., `継続システムID`). For list types, it follows the pattern `FieldPath/Index/SubField` (e.g., `サービス契約一覧リスト/0/planName`). For common-info items, it starts with `//`. If `null`, the method returns `null` immediately. |
| 2 | `subkey` | `String` | A sub-identifier within the field that specifies which attribute to retrieve. For scalar fields it is `value`, `state`, or `enable` (for boolean-enabled fields). For list elements it targets a specific sub-field of the child bean. If `null`, it is normalized to an empty string. |

**Instance fields read:**

| Field | Type | Business Description |

| `hktg_sysid_state` | `String` | The display/interaction state of the system ID field |
| `hktg_svc_kei_no_value` | `String` | The customer service category value |

| `hi_cust_nm_enabled` | `Boolean` | Whether the referral contract party name field is enabled |
| `hi_cust_nm_state` | `String` | The state of the referral contract party name field |
| `hi_telno_value` | `String` | The referral phone number value |
| `hi_telno_enabled` | `Boolean` | Whether the referral phone number field is enabled (default: `true`) |
| `hi_telno_state` | `String` | The state of the referral phone number field |
| `hi_sysid_value` | `String` | The referral system ID value |
| `hi_sysid_enabled` | `Boolean` | Whether the referral system ID field is enabled |
| `hi_sysid_state` | `String` | The state of the referral system ID field |
| `svc_kei_list_list` | `ArrayList` (of `X33VDataTypeBeanInterface`) | The service contract list — contains child beans for each service line item |
| `cust_kei_hktgi_list_list` | `ArrayList` (of `X33VDataTypeBeanInterface`) | The customer contract succession list — contains child beans for each customer contract item |
| `popup_mode_value` | `Object` (inferred) | The current popup mode value |
