## 1. Role

### FUW07101SF01DBean.loadModelData()

This method is the **central data-routing dispatcher** for the `FUW07101SF01DBean` view data bean, which powers the service contract management screen in the K-Opticom telecommunications management platform. Its purpose is to resolve a two-level lookup — a **key** (business field name in Japanese) and a **subkey** (`"value"` or `"state"`) — to the corresponding getter method on the bean.

The method handles **17 distinct data categories**, each representing a business attribute managed by the service contract screen. These categories fall into four groups:

1. **Product/Equipment attributes** (5 keys): Home terminal model code, equipment provision type code and name, sales type code and name — these describe the physical and commercial classification of the subscriber's equipment and service tier.
2. **Pricing attributes** (4 keys): Charge code and name, equipment-type applicable charge code application start date, and equipment-type applicable charge code application end date — these define the billing structure for the subscriber's plan.
3. **Audit trail fields** (6 keys): Registered date/time, registered operator account, updated date/time, updated operator account, deleted date/time, deleted operator account — these track the lifecycle of the service contract record.
4. **Lifecycle flags** (2 keys): Invalid flag and invalid flag name — these represent the soft-delete/deactivation state of the record.

For each category, the method dispatches to one of two getter methods based on the subkey: `"value"` returns the field's current data value, while `"state"` returns the field's validation/display state. This design implements the **routing/dispatch pattern** — a single public method that delegates to specialized getters based on parameterized key-based lookup, which is the standard `X33VDataTypeBeanInterface` contract for the X33 web framework.

As a shared utility, this method is the canonical entry point for the X33 framework's data-loading mechanism (`X31CBaseBean.loadModelData`). Any screen component that uses this DBean as its data model will call this method to fetch field values and states by name. If no matching key is found, or if either parameter is `null`, the method returns `null` gracefully.

**Processing flow summary:**

1. **Null guard (L533–L536):** If either `key` or `subkey` is `null`, immediately return `null`. This prevents `NullPointerException` when the key comparison logic runs.
2. **Separator computation (L538):** Compute `separaterPoint = key.indexOf("/")` — although this value is declared, it is never used in the method body. It appears to be residual/unused code.
3. **17-key routing chain (L541–L708):** A cascading `if`/`else if` chain checks `key` against 17 Japanese string literals, each representing a distinct business field. For each match, a nested check on `subkey.equalsIgnoreCase("value")` dispatches to either the `_value` or `_state` getter. This creates 34 unique return paths.
4. **Fallback (L711):** If no key matches any branch, the method returns `null`.

**No constants from `JZEStrConst` are used in this method.** The key literals are hardcoded Japanese strings directly in the conditional logic.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | **Business field name** — a Japanese-language string identifying which data attribute to retrieve. Must match one of 17 hardcoded literals such as `"宅内機器型式コード"` (Home Terminal Model Code) or `"登録年月日時分秒"` (Registered Date/Time). Controls the routing branch that determines which getter is invoked. |
| 2 | `subkey` | `String` | **Accessor type selector** — determines the data access mode. `"value"` (case-insensitive) returns the actual data value of the field (e.g., the current model code string). `"state"` (case-insensitive) returns the validation/display state string for UI rendering (e.g., whether the field is editable, required, or has validation errors). |

**Instance fields read by the method (via getter delegation):**

| Field | Type | Business Description |
|-------|------|---------------------|
| `taknkiki_model_cd_value` | `String` | Home terminal model code — the model identifier for the subscriber's internal wiring equipment |
| `taknkiki_model_cd_state` | `String` | Validation/display state for the home terminal model code field |
| `kktk_sbt_cd_value` | `String` | Equipment provision type code — classifies the type of equipment provision (e.g., rental, purchase) |
| `kktk_sbt_cd_nm_value` | `String` | Equipment provision type code name — human-readable name for the equipment provision type |
| `hambai_sbt_cd_value` | `String` | Sales type code — the commercial sales classification for this service contract |
| `hambai_sbt_cd_nm_value` | `String` | Sales type code name — human-readable name for the sales type |
| `pcrs_cd_value` | `String` | Charge code — the billing/charging classification code for this service |
| `pcrs_cd_nm_value` | `String` | Charge code name — human-readable name for the charge code |
| `kkmdl_tg_pcrs_tstaymd_value` | `String` | Equipment-type applicable charge code application start date — when the equipment-type charge plan begins |
| `kkmdl_tg_pcrs_tendymd_value` | `String` | Equipment-type applicable charge code application end date — when the equipment-type charge plan ends |
| `add_dtm_value` | `String` | Registered date/time (creation timestamp) — when this record was first inserted |
| `add_opeacnt_value` | `String` | Registered operator account — the user ID of the operator who created this record |
| `upd_dtm_value` | `String` | Updated date/time (modification timestamp) — when this record was last modified |
| `upd_opeacnt_value` | `String` | Updated operator account — the user ID of the operator who last modified this record |
| `del_dtm_value` | `String` | Deleted date/time (deletion timestamp) — when this record was soft-deleted |
| `del_opeacnt_value` | `String` | Deleted operator account — the user ID of the operator who deleted this record |

**Analysis:** This method performs **exclusively read (R) operations**. It contains no database access, no SC/CBS calls, no entity manipulation, and no write operations. All 34 method calls (17 keys x 2 subkey types) delegate to simple getter methods on the same bean class. The method is a **pure data-routing layer** with no side effects — it simply resolves a key/subkey pair to the appropriate getter and returns its result.

## 5. Dependency Trace

No external callers of `FUW07101SF01DBean.loadModelData(String, String)` were found in the codebase. This method is invoked through the **X33 framework's data loading mechanism** — when the framework's `X31CBaseBean` initialization process (or a listed-bean component) calls `loadModelData()` as part of the standard data-loading contract. Other `DBean` classes in the FUW009xxSF modules implement similar `loadModelData` patterns for their own field routing, but they are independent implementations, not callers.

**Notes:** The X33 framework's `X31CBaseBean.loadData()` iterates over the DBean's registered fields and calls `loadModelData()` for each field by its name key. The above rows represent the primary entry points through which the framework invokes this method during screen initialization — one per unique getter endpoint.
