Methods

`Abstract`close

close(): Promise<void>
Returns Promise<void>
- Defined in base.feature-flag-provider.ts:21

`Protected` `Abstract`getDefaultContext

getDefaultContext(): FlagContext | undefined
Implementation-specific default context (e.g. AsyncLocalStorage for LaunchDarkly, instance field for static tests).

Returns FlagContext | undefined
- Defined in base.feature-flag-provider.ts:27

`Abstract`getVariation

getVariation<T>(key: string, defaultValue: T, context?: FlagContext): Promise<T>
Type Parameters
- T
Parameters
- key: string
- defaultValue: T
- Optionalcontext: FlagContext
Returns Promise<T>
- Defined in base.feature-flag-provider.ts:20

`Abstract`identify

identify(context: FlagContext): Promise<void>
Sets the default evaluation context for this provider. When isEnabled / getVariation are called without an explicit context, the effective context is mergeFlagContext(getDefaultContext(), explicit) (implementation-specific).
Parameters
- context: FlagContext
Returns Promise<void>
- Defined in base.feature-flag-provider.ts:17

`Abstract`initialize

initialize(): Promise<void>
Returns Promise<void>
- Defined in base.feature-flag-provider.ts:10

`Abstract`isEnabled

isEnabled(key: string, context?: FlagContext): Promise<boolean>
Parameters
- key: string
- Optionalcontext: FlagContext
Returns Promise<boolean>
- Defined in base.feature-flag-provider.ts:19

`Protected`resolveEvaluationContext

resolveEvaluationContext(explicit?: FlagContext): FlagContext
Merges the default context with an explicit override for a single evaluation.
Parameters
- Optionalexplicit: FlagContext
Returns FlagContext
- Defined in base.feature-flag-provider.ts:32
