|

|
19 |
+
## π Basic Usage
|
20 |
|
21 |
```dart
|
22 |
final system = ActorSystem();
|
|
|
29 |
greeter.send(Greet('Alice'));
|
30 |
```

31 |

|
33 |

|
34 |
+
## π Remote Actors
|
35 |
|
36 |
+
Actory supports distributed actor systems spanning multiple nodes.
|
37 |
|
38 |
+
### Using `RemoteActorFactory` (Recommended)
|
39 |
|
40 |
```dart
|
|
|
41 |
final factory = RemoteActorFactory(
|
42 |
host: 'localhost',
|
43 |
port: 8080,
|
|
|
46 |
|
47 |
await factory.start();
|
48 |
|
|
|
49 |
await factory.createLocalActor<ChatMessage>(
|
50 |
'chat-actor',
|
51 |
ChatActor(),
|
52 |
(msg) => msg as ChatMessage,
|
53 |
);
|
54 |
|
|
|
55 |
factory.registerRemoteActor('remote-chat', 'ws://localhost:8081');
|
56 |
|
|
|
57 |
factory.sendMessage('chat-actor', ChatMessage('User', 'Hello!'));
|
58 |
factory.sendMessage('remote-chat', ChatMessage('User', 'Hello remote!'));
|
59 |
```
|
60 |
|
61 |
+
### Manual Remote Actor Setup
|
62 |
|
63 |
```dart
|
|
|
64 |
final clusterNode = ClusterNode('localhost', 8080);
|
65 |
final registry = ActorRegistry();
|
66 |
|
67 |
await clusterNode.start();
|
68 |
|
|
|
69 |
final localActor = await system.spawn<Message>(actor, decoder);
|
70 |
registry.registerLocal('my-actor', localActor);
|
71 |
|
|
|
72 |
registry.registerRemote('remote-actor', 'ws://localhost:8081');
|
73 |
|
|
|
74 |
final localRef = registry.get('my-actor');
|
75 |
final remoteRef = registry.get('remote-actor'); // Returns RemoteActorRef
|
76 |
|
|
|
77 |
localRef?.send(message);
|
78 |
remoteRef?.send(message);
|
79 |
```
|

|

|
82 |
|
83 |
+
## π SafeMap β Thread-Safe Data Structure
|
84 |
|
85 |
+
`SafeMap` provides atomic and thread-safe operations on shared state **within a single Dart isolate**. Since each actor runs in its own isolate, `SafeMap` is useful for shared data inside an isolate, while cross-isolate communication should use message passing.
|
86 |
+
|
87 |
+
### Usage Example
|
88 |
|
89 |
```dart
|
|
|
90 |
final sharedData = SafeMap<String, String>();
|
91 |
|
|
|
92 |
sharedData.set('key', 'value');
|
93 |
final value = sharedData.get('key');
|
94 |
|
|
|
95 |
final wasAdded = sharedData.putIfAbsent('key', () => 'default');
|
96 |
final computed = sharedData.getOrCompute('key', () => 'computed');
|
97 |
|
|
|
98 |
final wasUpdated = sharedData.updateIfPresent('key', (v) => 'updated_$v');
|
99 |
|
|
|
100 |
final keys = sharedData.keys;
|
101 |
final values = sharedData.values;
|
102 |
final entries = sharedData.entries;
|
103 |
|
|
|
104 |
final filtered = sharedData.where((key, value) => key.startsWith('user_'));
|
105 |
final transformed = sharedData.map((key, value) => MapEntry('new_$key', value.toUpperCase()));
|
106 |
|
|
|
107 |
sharedData.merge({'key2': 'value2'});
|
108 |
sharedData.mergeSafeMap(otherSafeMap);
|
109 |
|
|
|
110 |
final copy = sharedData.copy();
|
111 |
final regularMap = sharedData.toMap();
|
112 |
sharedData.clear();
|
113 |
```
|
114 |
|
115 |
+
### SafeMap in an Actor
|
116 |
|
117 |
```dart
|
118 |
class SharedStateActor extends Actor<dynamic> {
|
|
|
129 |
}
|
130 |
```
|
