Methods

collectDependencies() → Iterable<InjectorKey>

Available on ServiceDescriptor, provided by the ResolutionExtension extension

Collects all required dependencies of this service and its conditions.

collectOptionalDependencies() → Iterable<InjectorKey>

Available on ServiceDescriptor, provided by the ResolutionExtension extension

Collects all optional dependencies of this service and its conditions.

instantiate(Injector injector) → Future

isSatisfied(Injector injector) → bool

Available on ServiceDescriptor, provided by the ResolutionExtension extension

Verifies if the injector provides all required dependencies.

isSolvable(Injector injector, List<InjectorKey> futurePromises) → bool

Available on ServiceDescriptor, provided by the ResolutionExtension extension

Verifies if all required dependencies are either already provided by the injector or could still become available as promised by futurePromises.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

skipDependencyCycle(Injector injector, List<InjectorKey> futurePromises) → bool

Available on ServiceDescriptor, provided by the ResolutionExtension extension

Returns if the DarwinSystemServiceMixin should wait another dependency cycle before trying to create this service, either because it is currently lacking required dependencies, or optional dependencies are still being possibly promised by futurePromises.

start(DarwinSystem system, dynamic obj) → Future<void>

The start signal handler of this service.

override

stop(DarwinSystem system, dynamic obj) → Future<void>

The stop signal handler of this service.

override

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
