Interface Summary

Interface	Description
BaseEvaluation<T>	This is a common interface between the evaluation results that providers return and what is given to the end users.
BooleanHook	An extension point which can run around flag resolution.
Client	Interface used to resolve flags of varying types.
ClientMetadata	Metadata specific to an OpenFeature Client.
DoubleHook	An extension point which can run around flag resolution.
EvaluationContext	The EvaluationContext is a container for arbitrary contextual data that can be used as a basis for dynamic evaluation.
EventBus<T>	Interface for attaching event handlers.
FeatureProvider	The interface implemented by upstream flag providers to resolve flags for their service.
Features	An API for the type-specific fetch methods offered to users.
Hook<T>	An extension point which can run around flag resolution.
IntegerHook	An extension point which can run around flag resolution.
Metadata	Holds identifying information about a given entity.
StringHook	An extension point which can run around flag resolution.
Structure	Structure represents a potentially nested object type which is used to represent structured data.
TransactionContextPropagator	TransactionContextPropagator is responsible for persisting a transactional context for the duration of a single transaction.

Class Summary

Class	Description
EventDetails	The details of a particular event.
EventProvider	Abstract EventProvider.
FlagEvaluationDetails<T>	Contains information about how the provider resolved a flag, including the resolved value.
FlagEvaluationOptions
HookContext<T>	A data class to hold immutable context that Hook instances use.
ImmutableContext	The EvaluationContext is a container for arbitrary contextual data that can be used as a basis for dynamic evaluation.
ImmutableMetadata	Immutable Flag Metadata representation.
ImmutableMetadata.ImmutableMetadataBuilder	Immutable builder for ImmutableMetadata.
ImmutableStructure	ImmutableStructure represents a potentially nested object type which is used to represent structured data.
MutableContext	The EvaluationContext is a container for arbitrary contextual data that can be used as a basis for dynamic evaluation.
MutableStructure	MutableStructure represents a potentially nested object type which is used to represent structured data.
NoOpProvider	A FeatureProvider that simply returns the default values passed to it.
NoOpTransactionContextPropagator	A TransactionContextPropagator that simply returns empty context.
OpenFeatureAPI	A global singleton which holds base configuration for the OpenFeature library.
OpenFeatureClient	Deprecated // TODO: eventually we will make this non-public.
ProviderEvaluation<T>	Contains information about how the a flag was evaluated, including the resolved value.
ProviderEventDetails	The details of a particular event.
ThreadLocalTransactionContextPropagator	A ThreadLocalTransactionContextPropagator is a transactional context propagator that uses a ThreadLocal to persist a transactional context for the duration of a single thread.
Value	Values serve as a generic return type for structure data from providers.
