## 1. Role

### KKW02410SFLogic.executeInitSvc()

This method performs the **Femtocell Option Information Inquiry Service Execution Process (Initial Display)** — its Javadoc describes it as 「フェムトセルオプション情報照会サービス実行処理(初期表示用)」 (Femtocell option information inquiry service execution process for initial display). It serves as the primary entry point for loading femtocell option service data when a user first opens the femtocell option information inquiry screen.

The method implements a **Mapper-based data binding pattern** with service invocation. It creates three HashMaps (parameter, input, and output maps), configures the use-case identifier, invokes two mapping methods to bind DataBean fields into the input map (one for option service contract agreement and one for additional service items), delegates to a generic service dispatcher, and then maps the returned data back to the DataBean for screen display.

Its role in the larger system is to prepare and fetch all femtocell option inquiry data required by the initial screen load. It is called by `KKW02410SFLogic.actionInit()`, indicating it is the dedicated initialization handler for the femtocell option information screen. The method delegates the actual service execution to a shared `invokeService` infrastructure, which routes the request to the appropriate backend service component.

The method has no conditional branches — it follows a linear execution path, making it a straightforward data preparation and service invocation routine.

```

**Processing Description:**

1. **Map Creation (L199–L201):** Three `HashMap<String, Object>` instances are created — `paramMap` for parameter configuration, `inputMap` for input data, and `outputMap` for result storage.

2. **Use Case ID Setup (L203):** The `TELEGRAM_INFO_USECASE_ID` key is set to `"KKSV0577"` in `paramMap`, routing the service call to the femtocell option inquiry use case.

3. **Mapper Instantiation (L205):** A new instance of `KKSV0577_KKSV0577OPDBMapper` is created to handle DataBean-to-map mapping operations.

4. **Upper Mapping — Input Binding (L208–L209):** Two `set*SC` methods are called to map DataBean items into the input map. `setKKSV057701SC` uses `JPCModelConstant.FUNC_CD_2` and `setKKSV057702SC` uses `JPCModelConstant.FUNC_CD_1` to differentiate the mapping modes. These are described as 「オプションサービス契約同意照会」 (Option service contract agreement inquiry).

5. **Service Invocation (L211):** The generic `invokeService` method is called with all three maps, which dispatches to the appropriate backend service component via the `JCCBatCommon.invokeService` infrastructure.

6. **Lower Mapping — Output Binding (L214–L215):** Two `get*SC` methods map the service output data back into the `paramBean` fields for screen display. These are the inverse operations of the `set*SC` calls above.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `paramBean` | `X31SDataBeanAccess[]` | Array of DataBean objects representing the femtocell option information inquiry screen's data model. Fields within these beans carry business data such as femtocell option contract status, service agreement details, and inquiry result data. Passed by reference — modified by `set*SC` (input binding) and `get*SC` (output binding) mapping methods. |

**External/Instance State Read:**
| Source | Description |
|--------|-------------|
| `invokeService(paramMap, inputMap, outputMap)` | Inherited from parent class `KKW02410SFLogic` — delegates service execution to `JCCBatCommon.invokeService`, which routes to the appropriate backend service component (e.g., `JBSBatKKCrsChgIktAdd`, `JBSbatKKCrsChgSmtVLAdd`, etc.) |

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `KKSV0577_KKSV0577OPDBMapper.setKKSV057701SC` | KKSV057701SC | - | Maps DataBean input fields to inputMap for option service contract agreement inquiry (Upper mapping) |
| - | `KKSV0577_KKSV0577OPDBMapper.setKKSV057702SC` | KKSV057702SC | - | Maps DataBean input fields to inputMap for additional option service items inquiry (Upper mapping) |
| R | `JCCBatCommon.invokeService` | Varies by use case | Backend entities | Invokes the service infrastructure to execute the femtocell option inquiry service with inputMap and returns results in outputMap |
| R | `KKSV0577_KKSV0577OPDBMapper.getKKSV057701SC` | KKSV057701SC | - | Maps outputMap results back to DataBean fields for option service contract agreement inquiry (Lower mapping) |
| R | `KKSV0577_KKSV0577OPDBMapper.getKKSV057702SC` | KKSV057702SC | - | Maps outputMap results back to DataBean fields for additional option service items inquiry (Lower mapping) |

**Classification Notes:**
- `set*SC` methods: These are **mapping/transform** operations (upper mapping from DataBean to inputMap). They populate the input parameters before service invocation.
- `invokeService`: This is an **R (Read)** operation — it queries backend data for femtocell option information and returns results via `outputMap`. The actual service component invoked depends on the use case ID `"KKSV0577"`.
- `get*SC` methods: These are **R (Read)** operations (lower mapping from outputMap back to DataBean). They extract the service results and populate the DataBean for screen rendering.

## 5. Dependency Trace

### Pre-computed evidence from code analysis graph:

No screen/batch entry points found within 8 hops. Direct callers found: 1 methods.
Terminal operations from this method: `getKKSV057702SC` [R], `getKKSV057701SC` [R], `invokeService` [-], `invokeService` [-], `invokeService` [-], `invokeService` [-], `invokeService` [-], `setKKSV057702SC` [-], `setKKSV057701SC` [-]

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | KKW02410SFLogic.actionInit() | `actionInit()` → `executeInitSvc(paramBean)` | `getKKSV057701SC [R]`, `getKKSV057702SC [R]`, `invokeService [-] (routed via KKSV0577 use case)` |

**Call Chain Details:**
- `KKW02410SFLogic.actionInit()` is the direct caller. It triggers this method during the screen initialization phase. This action method is likely registered as the init handler for the femtocell option information inquiry screen, which corresponds to use case `KKSV0577`.

## 6. Per-Branch Detail Blocks

| 3 | SET | `HashMap<String, Object> outputMap = new HashMap<String, Object>();` // 結果格納用マップ (HashMap for result storage) (L201) |

**Block 2** — [LINEAR PROCESSING] (L203)

> Use case ID setup — configures the TELEGRAM_INFO_USECASE_ID to route the service call to the KKSV0577 femtocell option inquiry use case.

| # | Type | Code |
|---|------|------|
| 1 | SET | `paramMap.put(X31CWebConst.TELEGRAM_INFO_USECASE_ID, "KKSV0577");` // Set use case ID for routing (L203) [-> TELEGRAM_INFO_USECASE_ID = key for use case routing] |

**Block 3** — [LINEAR PROCESSING] (L205)

> Mapper instantiation — creates a new instance of `KKSV0577_KKSV0577OPDBMapper` to handle DataBean-to-map mapping operations for the KKSV0577 use case.

| # | Type | Code |
|---|------|------|
| 1 | SET | `KKSV0577_KKSV0577OPDBMapper mapper = new KKSV0577_KKSV0577OPDBMapper();` // オプションサービス契約同意照会 (Option service contract agreement inquiry mapper) (L205) |

**Block 4** — [LINEAR PROCESSING] (L208)

> Upper mapping 1 — Maps DataBean fields into the inputMap for option service contract agreement inquiry. Uses `JPCModelConstant.FUNC_CD_2` as the mapping function code.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `mapper.setKKSV057701SC(paramBean, inputMap, JPCModelConstant.FUNC_CD_2);` // オプションサービス契約同意照会 (Option service contract agreement inquiry upper mapping) (L208) [-> FUNC_CD_2 = function code for contract agreement] |

**Block 6** — [LINEAR PROCESSING] (L211)
