## 1. Role

### Mover.getBeanMapListFromDataBeanArray()

This method is a **batch data transformer** that converts an array of structured data beans (`X31SDataBeanAccessArray`) into a list of `BeanMap` objects. In the broader webview layer, `X31SDataBeanAccessArray` holds raw data records retrieved from the presentation or business tier, while `BeanMap` provides a map-based view suitable for screen rendering or further processing. The method delegates the per-bean conversion to `getBeanMapFromDataBean()`, applying the same transformation logic independently to each element in the array. This follows a **map-pattern** design: iterate over a collection, apply a unary transformation, and collect results into a new list. Its role is that of a **shared utility** within the `Mover` helper class — it is called by other methods in the same class (e.g., `getBeanMapFromDataBean()`) that need to convert entire data arrays into map-based representations for downstream processing.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["getBeanMapListFromDataBeanArray(beanArray, structure)"])
    STEP1["Extract count = beanArray.getCount()"]
    STEP2["Create empty ArrayList<BeanMap> result with capacity = count"]
    STEP3["Initialize loop counter i = 0"]
    STEP4{"i < count ?"}
    STEP5["Get bean = beanArray.getDataBean(i)"]
    STEP6["Convert bean to BeanMap via getBeanMapFromDataBean(bean, structure)"]
    STEP7["Add BeanMap to result list"]
    STEP8["Increment i"]
    STEP9["Return result"]

    START --> STEP1 --> STEP2 --> STEP3 --> STEP4
    STEP4 -- "Yes" --> STEP5 --> STEP6 --> STEP7 --> STEP8 --> STEP4
    STEP4 -- "No" --> STEP9
```

This method performs a straightforward **map-and-collect** iteration:
1. **Extract count** — Determines the number of beans in the array via `beanArray.getCount()`.
2. **Pre-allocate** — Creates the result `ArrayList` with the exact capacity to avoid resize overhead.
3. **Iterate** — For each bean index, retrieves the bean, converts it to a `BeanMap` via the delegated `getBeanMapFromDataBean()` call, and appends it to the result list.
4. **Return** — Once all beans are processed, the completed list is returned.

There are no conditional branches or constant-based routing in this method. The processing is uniform across all elements.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `beanArray` | `X31SDataBeanAccessArray` | A collection of data beans representing raw records to be transformed. Each bean holds fields that correspond to business data entities (e.g., service contracts, orders). The array's `getCount()` determines the iteration size. |
| 2 | `structure` | `Object[]` | A metadata or structure descriptor passed through to the per-bean conversion (`getBeanMapFromDataBean`). Likely defines field mappings, ordering, or display configuration for the target `BeanMap` output. |

**External/Instance State:**
- This method is **static** and does not read any instance fields or external state.

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `Mover.getBeanMapFromDataBean` | — | — | Converts a single `X31SDataBeanAccess` bean into a `BeanMap` (read-only transformation). |
| R | `X31SDataBeanAccessArray.getCount` | — | — | Returns the number of data beans in the array. |
| R | `X31SDataBeanAccessArray.getDataBean` | — | — | Retrieves the data bean at the specified index from the array. |

All operations in this method are **Read** — it transforms existing data without creating, updating, or deleting any records in the database.

## 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: `getBeanMapFromDataBean` [R], `getDataBean` [R], `getCount` [R]

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Method: `Mover.getBeanMapFromDataBean` | `getBeanMapFromDataBean` -> `getBeanMapListFromDataBeanArray` | `getBeanMapFromDataBean` [R], `getDataBean` [R], `getCount` [R] |

This method is a utility called internally by `Mover.getBeanMapFromDataBean()`, which is itself invoked within the `KKW01021SFLogic` flow. It operates entirely within the utility/helper tier and does not directly reach database or service components.

## 6. Per-Branch Detail Blocks

**Block 1** — SET (L1381)

Extract the bean count from the array to determine iteration size.

| # | Type | Code |
|---|------|------|
| 1 | SET | `count = beanArray.getCount().intValue()` // Number of data beans in the input array |

**Block 2** — SET (L1382)

Pre-allocate the result list with capacity to minimize resizing.

| # | Type | Code |
|---|------|------|
| 1 | SET | `result = new ArrayList<BeanMap>(count)` // Empty result list with initial capacity = count |

**Block 3** — FOR (condition: `i < count`) (L1383–1388)

Iterate over each data bean in the array, convert it, and collect into the result list.

| # | Type | Code |
|---|------|------|
| 1 | SET | `i = 0` // Loop counter initialization |
| 2 | CONDITION | `i < count` // Continue while index is within array bounds |

**Block 3.1** — FOR-BODY (L1384–1387)

| # | Type | Code |
|---|------|------|
| 1 | SET | `bean = beanArray.getDataBean(i)` // Retrieve the data bean at index i |
| 2 | SET | `content = getBeanMapFromDataBean(bean, structure)` // Convert single bean to BeanMap |
| 3 | SET | `result.add(content)` // Append converted BeanMap to result list |
| 4 | EXEC | `i++` // Increment loop counter |

**Block 4** — RETURN (L1389)

Return the fully populated list of `BeanMap` objects.

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return result` // Returns ArrayList<BeanMap> containing converted beans |
