modelType

modelType: string

The type of the model to be injected.

Optional id

id?: string

The id of the model to be injected.

The options to be passed to the model constructor.

Optional lifecycle

lifecycle?: DependencyLifecycle

The lifecycle at which the dependency should be injected.

Optional resolutionPolicy

resolutionPolicy?: DependencyResolutionPolicy

Policy for handling dependency resolution failures.

All policies first attempt to look up an existing model instance. If found and the type matches, the existing instance is returned. Only if lookup fails does the policy apply:

  • CREATE (default): Attempts to create model instance after lookup fails
  • CONTINUE: Returns undefined after lookup fails, allows graceful degradation
  • FAIL: Throws exception with detailed logging after lookup fails
