ExtensionRegistry class

Registry that owns extension lifecycle dispatch for the host binding.

Enforces:

  • namespace shape (^[a-z][a-z0-9_]*$) and uniqueness,
  • mandatory <namespace>.<tool> prefixing and bare-token tool names,
  • registration-order preservation across every dispatch,
  • per-method exception isolation with three-strike tripping (PRD §17).

Diagnostics are emitted through the injected logger (the Flutter host passes debugPrint); pure-Dart hosts may pass print or a no-op.

Constructors

ExtensionRegistry({void logger(String message)?})

Properties

extensions → List<LeonardExtension>
All registered extensions, in registration order. Read by the binding's single observation loop, which gates on is PerceptionExtension.
no setter
handshakeManifest → List<({String namespace, List<Map<String, Object?>> toolDescriptors, List<String> tools})>
Handshake manifest carrying each registered tool's device-owned description and raw input schema alongside the legacy bare-name list.
no setter
hashCode → int
The hash code for this object.
no setterinherited
manifest → List<({String namespace, List<String> tools})>
Extension manifest: ordered (namespace, bare tool names) records, one per registered extension (post de-duplication).
no setter
namespaces → List<String>
Extension namespaces in registration order (post de-duplication).
no setter
runtimeType → Type
A representation of the runtime type of the object.

Methods

busyStateAll() → Future<List<MapEntry<String, BusyState>>>
Dispatch busyState across every extension whose method is not tripped, in registration order. Failures yield BusyState.idle for the affected extension.
disposeAll() → Future<void>
Call LeonardExtension.dispose on every registered extension in registration order. Each call is exception-isolated; every extension is disposed even if earlier ones throw.
finalize() → Map<String, LeonardTool>
Alias for mergedTools.
initializeAll() → Future<void>
Call LeonardExtension.initialize on every registered extension in registration order. Failures are logged and mark the extension as failed; the call never rethrows.
mergedTools() → Map<String, LeonardTool>
Compute the merged tool list keyed by fully-qualified name.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onActionExecutedAll(ExecutedAction action) → Future<void>
Dispatch onActionExecuted across every extension whose method is not tripped, in registration order.
register(LeonardExtension p) → void
Register p. Order is preserved across every dispatch.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
