(JSON)", "isActive": true, "createdDate": "datetime", "modifiedDate": "datetime" } ``` ### Business Rules - VehicleTypeId must be unique - Cannot delete if referenced by Node/Edge properties - Soft delete via IsActive flag (recommended) --- ## 3️⃣ NodesController **Base Route:** `/api/nodes` **Purpose:** Node retrieval and update (creation via EdgesController) ### Endpoints ```http GET /api/nodes/level/{layoutLevelId:guid} # Get all nodes for level GET /api/nodes/{id:guid} # Get node by Id PUT /api/nodes/{id:guid} # Update node ``` **Note:** Node creation is automatic when creating edges (smart detection) ### DTOs **NodeDto:** ```csharp { "id": "guid", "levelId": "guid", "nodeId": "string (GUID 8-char)", "nodeName": "string", "nodeDescription": "string?", "mapId": "string?", "x": 12.5, // meters "y": 8.3, // meters "vehicleProperties": [ { "id": "guid", "nodeId": "guid", "vehicleTypeId": "guid", "theta": 1.57, // radians "actions": "[{\"actionType\":\"pick\"}]" // JSON } ] } ``` ### Update Rules - Can update: NodeName, NodeDescription, MapId, X, Y, VehicleProperties - Cannot change: Id, LevelId, NodeId - Validates X, Y within bounds (if configured in EditorSettings) --- ## 4️⃣ StationsController **Base Route:** `/api/stations` **Purpose:** Station CRUD operations ### Endpoints ```http POST /api/stations # Create station GET /api/stations/level/{layoutLevelId:guid} # Get all stations GET /api/stations/{id:guid} # Get by Id PUT /api/stations/{id:guid} # Update station DELETE /api/stations/{id:guid} # Delete station ``` ### DTOs **StationDto:** ```csharp { "id": "guid", "levelId": "guid", "stationId": "string (unique within level)", "stationName": "string", "stationDescription": "string?", "stationHeight": 1.5, // meters, optional "x": 10.0, // meters "y": 5.0, // meters "theta": 0.0, // radians, optional "interactionNodes": [ { "id": "guid", "stationId": "guid", "nodeId": "guid" } ] } ``` ### Cascade Delete Rules When deleting a station: - ✅ Deletes StationInteractionNodes - ❌ Does NOT delete referenced Nodes --- ## 5️⃣ EdgesController ⭐ **Base Route:** `/api/edges` **Purpose:** Edge CRUD with smart node detection ### Endpoints ```http GET /api/edges/level/{layoutLevelId:guid} # Get all edges GET /api/edges/{id:guid} # Get by Id POST /api/edges # Create (smart detection) PUT /api/edges/{id:guid} # Update edge DELETE /api/edges/{id:guid} # Delete (orphan cleanup) DELETE /api/edges/batch # Batch delete (transaction) ``` ### Smart Edge Creation ⭐ **Request:** ```csharp { "layoutLevelId": "guid", "x1": 10.0, // Start point (meters) "y1": 5.0, "x2": 15.0, // End point (meters) "y2": 8.0, "edgeName": "string? (optional)", "vehicleProperties": [...] // optional } ``` **Logic Flow:** ``` 1. Load LayoutLevelEditorSettings for the level ├─ Get NodeProximityRadius (default: 0.35m) ├─ Get EdgeMinLengthCreate (default: 0.5m) └─ Get AutoGenerate flags 2. Find or Create Start Node: ├─ Search existing nodes within NodeProximityRadius of (X1, Y1) ├─ If found → Use existing node └─ If not found → Create new node with GUID name at (X1, Y1) 3. Find or Create End Node: ├─ Search existing nodes within NodeProximityRadius of (X2, Y2) ├─ If found → Use existing node └─ If not found → Create new node with GUID name at (X2, Y2) 4. Validate Edge: ├─ Check StartNode != EndNode ├─ Check edge length >= EdgeMinLengthCreate └─ Check no duplicate edge between same nodes 5. Create Edge: ├─ Generate EdgeId (GUID 8-char if auto-generate) ├─ Link StartNodeId and EndNodeId └─ Add VehicleProperties if provided 6. Save to database (transaction) ``` **Distance Calculation:** ```csharp double distance = Math.Sqrt(Math.Pow(node.X - x, 2) + Math.Pow(node.Y - y, 2)); if (distance <= settings.NodeProximityRadius) return node; // Use existing node ``` ### Cascade Delete Rules ⭐ When deleting an edge: ``` 1. Delete EdgeVehicleProperties (FK CASCADE) 2. Check StartNode: ├─ Count edges connected to StartNode ├─ If count == 0 (orphan): │ ├─ Delete NodeVehicleProperties │ ├─ Delete StationInteractionNodes │ └─ Delete Node └─ Else: Keep node 3. Check EndNode: ├─ Count edges connected to EndNode ├─ If count == 0 (orphan): │ ├─ Delete NodeVehicleProperties │ ├─ Delete StationInteractionNodes │ └─ Delete Node └─ Else: Keep node 4. All operations in transaction ``` ### Batch Delete **Request:** ```csharp { "edgeIds": ["guid1", "guid2", "guid3"] } ``` **Response:** ```csharp { "deletedEdgesCount": 3, "deletedNodesCount": 2, // Orphaned nodes cleaned up "message": "Successfully deleted 3 edges and 2 orphan nodes" } ``` - ✅ Transaction ensures atomicity - ✅ Cascade delete for all edges - ✅ Returns summary --- ## 6️⃣ LayoutDataController **Base Route:** `/api/layoutdata` **Purpose:** Comprehensive data retrieval for MapEditor ### Endpoint ```http GET /api/layoutdata/{layoutLevelId:guid} ``` ### Response Structure **LayoutDataDto:** ```csharp { "layoutLevelId": "guid", "layoutLevelName": "string", "nodes": [ { "id": "guid", "nodeId": "string", "nodeName": "string", "x": 10.0, "y": 5.0, "vehicleProperties": [...] } ], "edges": [ { "id": "guid", "edgeId": "string", "edgeName": "string", "startNodeId": "guid", "endNodeId": "guid", "vehicleProperties": [ { "vehicleTypeId": "guid", "orientationType": "TANGENTIAL", // enum "rotationAtStartNodeAllowed": "CCW", // enum "rotationAtEndNodeAllowed": "BOTH", // enum "maxSpeed": 2.0, "trajectory": "{...}" // JSON } ] } ], "stations": [ { "id": "guid", "stationId": "string", "stationName": "string", "x": 12.0, "y": 6.0, "theta": 1.57, "interactionNodes": [...] } ] } ``` ### Use Case MapEditor loads entire level data in **one request** for rendering: - All nodes with vehicle properties - All edges with vehicle properties - All stations with interaction nodes Efficient for UI rendering and caching. --- ## 7️⃣ LayoutManagerController **Base Route:** `/api/layouts` **Purpose:** Layout/Version/Level management + Import/Export ### Endpoints Overview **Layout Management (9):** ```http POST /api/layouts # Create layout GET /api/layouts # Get all GET /api/layouts/{id:guid} # Get by Id GET /api/layouts/layoutId/{layoutId} # Get by LayoutId GET /api/layouts/search?query={text} # Search PUT /api/layouts/{id:guid} # Update PUT /api/layouts/{id:guid}/activate # Activate PUT /api/layouts/{id:guid}/deactivate # Deactivate DELETE /api/layouts/{id:guid} # Delete ``` **Version Management (5):** ```http POST /api/layouts/{layoutId:guid}/versions # Create version GET /api/layouts/{layoutId:guid}/versions # Get all versions GET /api/layouts/versions/{versionId:guid} # Get by Id PUT /api/layouts/versions/{versionId:guid}/activate # Activate version DELETE /api/layouts/versions/{versionId:guid} # Delete version ``` **Level Management (5):** ```http POST /api/layouts/versions/{versionId:guid}/levels # Create level GET /api/layouts/versions/{versionId:guid}/levels # Get all levels GET /api/layouts/levels/{levelId:guid} # Get by Id PUT /api/layouts/levels/{levelId:guid} # Update level DELETE /api/layouts/levels/{levelId:guid} # Delete level ``` **Import/Export (2):** ```http POST /api/layouts/import # Import VDMA LIF JSON GET /api/layouts/{id}/export?version={v} # Export VDMA LIF JSON ``` ### Business Rules **Layout:** - Only ONE active layout at a time - Activate → deactivates others - Cannot delete if IsActive = true - Delete cascades to versions → levels → nodes/edges/stations **LayoutVersion:** - Only ONE active version per layout - Version format: "X.Y" (e.g., "1.0", "2.3") - Activate → deactivates other versions of same layout **LayoutLevel:** - LayoutLevelId unique within version - LevelOrder for UI sorting - Auto-creates LayoutLevelEditorSettings with defaults: - EdgeMinLengthCreate: 0.5 - NodeNameAutoGenerate: true - EdgeNameAutoGenerate: true - OriginX, OriginY: 0.0 - Resolution: 0.05 - NodeProximityRadius: 0.35 ### Import Logic **VDMA LIF JSON → Database:** ```csharp 1. Parse VDMA LIF JSON 2. Create/Update Layout (by layoutId) 3. Create/Update LayoutVersion (by version) 4. For each layoutLevelId: a. Create/Update LayoutLevel b. Import Nodes (auto GUID if needed) c. Import Edges d. Import Stations e. Import VehicleProperties f. Auto-create EditorSettings 5. Transaction commit ``` ### Export Logic **Database → VDMA LIF JSON:** ```json { "metaInformation": { "creator": "RobotNet10.MapManager", "exportDate": "2024-11-26T10:00:00Z" }, "layouts": [ { "layoutId": "warehouse_main", "layoutVersion": "1.0", "layoutLevelId": "floor_1", "nodes": [...], "edges": [...], "stations": [...] } ] } ``` **Important:** ❌ Do NOT export LayoutLevelEditorSettings (internal only) --- ## 🎨 Enum Types ### 1. OrientationType **File:** `RobotNet10.MapEditor.Shared/Enums/OrientationType.cs` ```csharp public enum OrientationType { GLOBAL = 0, // Absolute to map origin TANGENTIAL = 1 // Follows edge direction } ``` **Used in:** EdgeVehicleProperty.OrientationType ### 2. RotationDirection **File:** `RobotNet10.MapEditor.Shared/Enums/RotationDirection.cs` ```csharp public enum RotationDirection { NONE = 0, // No rotation CCW = 1, // Counter-clockwise CW = 2, // Clockwise BOTH = 3 // Both directions } ``` **Used in:** - EdgeVehicleProperty.RotationAtStartNodeAllowed - EdgeVehicleProperty.RotationAtEndNodeAllowed ### 3. StorageType **File:** `RobotNet10.MapEditor.Shared/Enums/StorageType.cs` ```csharp public enum StorageType { FileSystem = 0, Minio = 1 } ``` **Used in:** ImageStorageOptions configuration ### Database Storage Enums stored as `INTEGER`: - GLOBAL/NONE/FileSystem = 0 - TANGENTIAL/CCW/Minio = 1 - CW = 2 - BOTH = 3 ### JSON Serialization ASP.NET Core serializes enums as **strings** in JSON: ```json { "orientationType": "TANGENTIAL", "rotationAtStartNodeAllowed": "CCW" } ``` Invalid values return **400 Bad Request** automatically. --- ## 🛠️ Services Layer ### Service Overview | Service | Lines | Responsibility | |---------|-------|----------------| | **IImageStorageService** | ~40 | Image storage interface | | **FileSystemImageStorageService** | ~110 | Local file storage | | **IVehicleTypeService** | ~50 | VehicleType interface | | **VehicleTypeService** | ~130 | VehicleType CRUD | | **INodeService** | ~30 | Node interface | | **NodeService** | ~150 | Node operations | | **IStationService** | ~30 | Station interface | | **StationService** | ~160 | Station CRUD | | **IEdgeService** | ~35 | Edge interface | | **EdgeService** | ~320 | Edge + smart detection | | **ILayoutDataService** | ~20 | Data aggregation | | **LayoutDataService** | ~150 | Comprehensive queries | | **ILayoutService** | ~60 | Layout management | | **LayoutService** | ~420 | Layout + Import/Export | | **LayoutLevelNamingService** | ~213 | GUID name generation | | **TOTAL** | **~1,918** | | ### Key Service: EdgeService **Complex Business Logic:** ```csharp public async Task CreateEdgeAsync(CreateEdgeRequest request) { // 1. Load editor settings var settings = await _context.LayoutLevelEditorSettings .FirstOrDefaultAsync(s => s.LevelId == request.LayoutLevelId); if (settings == null) throw new InvalidOperationException("EditorSettings not found"); // 2.
