Service Tree Implementation
The ServiceTree is a core component in the Matrix Framework that manages hierarchical service relationships and message routing across distributed endpoints.
Core Implementation
public class ServiceTree : CommunicationElement
{
// Root Service Property
public static readonly DependencyProperty RootServiceProperty = DependencyProperty.Register(
"RootService",
typeof(ServiceNode),
typeof(ServiceTree),
new CommunicationPropertyMetadata(
null,
CommunicationPropertyMetadataOptions.AffectsMessaging |
CommunicationPropertyMetadataOptions.AffectsRouting
)
);
public ServiceNode RootService
{
get => (ServiceNode)GetValue(RootServiceProperty);
set => SetValue(RootServiceProperty, value);
}
// Network Topology Management
protected override async Task ProcessMessageAsync(NetworkMessage message)
{
foreach (ServiceNode node in RegisteredServices)
{
await node.ProcessMessageAsync(message);
}
return;
}
protected override async Task UpdateTopologyAsync(NetworkTopology topology)
{
// Update service hierarchy based on network topology
return;
}
}Service Discovery Integration
For advanced service discovery and routing:
public class ServiceDiscoveryManager
{
private readonly ServiceTree _tree;
private readonly IServiceRegistry _registry;
public ServiceDiscoveryManager(ServiceTree tree, IServiceRegistry registry)
{
_tree = tree;
_registry = registry;
}
public async Task RegisterServiceAsync(ServiceEndpoint endpoint)
{
// Register service with the network
await _registry.RegisterAsync(endpoint);
// Create service node
var node = new ServiceNode
{
Endpoint = endpoint,
State = ServiceState.Active
};
// Add to service tree
_tree.AddService(node);
}
}Usage in Matrix XAML
<Matrix xmlns="http://schemas.matrix.com/framework/2024">
<ServiceTree>
<ServiceNode Name="AuthService"
Endpoint="tcp://auth.services.local:5000">
<ServiceNode Name="UserManagement"
Endpoint="tcp://users.services.local:5001">
<ServiceNode Name="ProfileService"
Endpoint="tcp://profiles.services.local:5002" />
</ServiceNode>
</ServiceNode>
</ServiceTree>
</Matrix>Network Integration
public class NetworkServiceAdapter
{
private readonly ServiceTree _tree;
private readonly INetworkDispatcher _dispatcher;
public NetworkServiceAdapter(ServiceTree tree, INetworkDispatcher dispatcher)
{
_tree = tree;
_dispatcher = dispatcher;
}
public async Task BroadcastMessageAsync(NetworkMessage message)
{
var services = _tree.GetServicesInScope(message.Scope);
foreach (var service in services)
{
await _dispatcher.SendAsync(service.Endpoint, message);
}
}
public async Task RouteMessageAsync(NetworkMessage message)
{
var route = _tree.CalculateRoute(
message.SourceEndpoint,
message.TargetEndpoint
);
foreach (var hop in route)
{
await _dispatcher.SendAsync(hop, message);
}
}
