-## Overview - -This document summarizes the implementation of object message handling logic in the ably-java liveobjects module, -based on the JavaScript implementation in ably-js. - -## JavaScript Implementation Analysis - -### Flow Overview - -The JavaScript implementation follows this flow: - -1. **Entry Point**: `RealtimeChannel.processMessage()` receives protocol messages with `OBJECT` or `OBJECT_SYNC` actions -2. **Message Routing**: - - `OBJECT` action → `this._objects.handleObjectMessages()` - - `OBJECT_SYNC` action → `this._objects.handleObjectSyncMessages()` -3. **State Management**: Objects have states: `initialized`, `syncing`, `synced` -4. **Buffering**: Non-sync messages are buffered when state is not `synced` -5. **Sync Processing**: Sync messages are applied to a data pool and then applied to objects -6. **Operation Application**: Individual operations are applied to objects with serial-based conflict resolution - -### Key Components - -- **ObjectsPool**: Manages live objects by objectId -- **SyncObjectsDataPool**: Temporarily stores sync data before applying to objects -- **Buffered Operations**: Queues operations during sync sequences -- **Serial-based Conflict Resolution**: Uses site serials to determine operation precedence - -## Kotlin Implementation - -### Files Modified/Created - -1. **DefaultLiveObjects.kt** - Main implementation with state management and message handling -2. **LiveObjectImpl.kt** - Concrete implementations of LiveMap and LiveCounter - -### Key Features Implemented - -#### 1. State Management -```kotlin -private enum class ObjectsState { - INITIALIZED, - SYNCING, - SYNCED -} -``` - -#### 2. Message Handling -- **handle()**: Main entry point for protocol messages -- **handleObjectMessages()**: Processes regular object messages -- **handleObjectSyncMessages()**: Processes sync messages - -#### 3. Sync Processing -- **parseSyncChannelSerial()**: Extracts syncId and syncCursor from channel serial -- **startNewSync()**: Begins new sync sequence -- **endSync()**: Completes sync sequence and applies buffered operations -- **applySync()**: Applies sync data to objects pool - -#### 4. Object Operations -- **applyObjectMessages()**: Applies individual operations to objects -- **createZeroValueObjectIfNotExists()**: Creates placeholder objects for operations -- **parseObjectId()**: Parses object IDs to determine type - -#### 5. LiveObject Implementations -- **BaseLiveObject**: Abstract base class with common functionality -- **LiveMapImpl**: Concrete implementation for map objects -- **LiveCounterImpl**: Concrete implementation for counter objects - -### Implementation Details - -#### Serial-based Conflict Resolution -```kotlin -protected fun canApplyOperation(opSerial: String?, opSiteCode: String?): Boolean { - val siteSerial = siteTimeserials[opSiteCode] - return siteSerial == null || opSerial > siteSerial -} -``` - -#### CRDT Semantics for Maps -```kotlin -private fun canApplyMapOperation(mapEntrySerial: String?, opSerial: String?): Boolean { - // For LWW CRDT semantics, operation should only be applied if its serial is strictly greater - if (mapEntrySerial.isNullOrEmpty() && opSerial.isNullOrEmpty()) { - return false - } - if (mapEntrySerial.isNullOrEmpty()) { - return true - } - if (opSerial.isNullOrEmpty()) { - return false - } - return opSerial > mapEntrySerial -} -``` - -#### State Transitions -1. **INITIALIZED** → **SYNCING**: When first sync message received -2. **SYNCING** → **SYNCED**: When sync sequence completes -3. **SYNCED**: Normal operation state - -#### Buffering Strategy -- Regular object messages are buffered during sync sequences -- Buffered messages are applied after sync completion -- This ensures consistency and prevents race conditions - -### Comparison with JavaScript - -| Feature | JavaScript | Kotlin | -|---------|------------|--------| -| State Management | `ObjectsState` enum | `ObjectsState` enum | -| Object Pool | `ObjectsPool` class | `ConcurrentHashMap` | -| Sync Data Pool | `SyncObjectsDataPool` class | `ConcurrentHashMap` | -| Buffering | `_bufferedObjectOperations` array | `bufferedObjectOperations` list | -| Serial Parsing | `_parseSyncChannelSerial()` | `parseSyncChannelSerial()` | -| CRDT Logic | `_canApplyMapOperation()` | `canApplyMapOperation()` | - -### Thread Safety - -The Kotlin implementation uses: -- `ConcurrentHashMap` for thread-safe collections -- Immutable data structures where possible -- Proper synchronization for state changes - -### Error Handling - -- Validates object IDs and operation parameters -- Logs warnings for malformed messages -- Throws appropriate exceptions for invalid states -- Graceful handling of missing serials or site codes - -### Future Enhancements - -1. **Event Emission**: Implement proper event emission for object updates -2. **Lifecycle Events**: Add support for object lifecycle events (created, deleted) -3. **Garbage Collection**: Implement GC for tombstoned objects -4. **Performance Optimization**: Add caching and optimization for frequently accessed objects -5. **Testing**: Comprehensive unit and integration tests - -## Compliance with Specification - -The implementation follows the Ably LiveObjects specification (PR #333) and maintains compatibility with the JavaScript implementation while leveraging Kotlin's type safety and concurrency features. diff --git a/live-objects/src/main/kotlin/io/ably/lib/objects/ObjectsManager.kt b/live-objects/src/main/kotlin/io/ably/lib/objects/ObjectsManager.kt index 7055b50b6..18c9d1494
