Interface Summary

Interface	Description
EventProcessor	Interface for an object that can send or store analytics events.
EventProcessorFactory	Interface for a factory that creates some implementation of EventProcessor.
FeatureStore	A thread-safe, versioned store for feature flags and related objects received from the streaming API.
FeatureStoreFactory	Interface for a factory that creates some implementation of FeatureStore.
LDClientInterface	This interface defines the public methods of LDClient.
UpdateProcessor	Interface for an object that receives updates to feature flags, user segments, and anything else that might come from LaunchDarkly, and passes them to a FeatureStore.
UpdateProcessorFactory	Interface for a factory that creates some implementation of UpdateProcessor.
VersionedData	Common interface for string-keyed, versioned objects that can be kept in a FeatureStore.

Class Summary

Class	Description
Components	Provides configurable factories for the standard implementations of LaunchDarkly component interfaces.
EvaluationDetail<T>	An object returned by the "variation detail" methods such as LDClientInterface.boolVariationDetail(String, LDUser, boolean), combining the result of a flag evaluation with an explanation of how it was calculated.
EvaluationReason	Describes the reason that a flag evaluation produced a particular value.
EvaluationReason.Error	Deprecated This type will be removed in a future version.
EvaluationReason.Fallthrough	Deprecated This type will be removed in a future version.
EvaluationReason.Off	Deprecated This type will be removed in a future version.
EvaluationReason.PrerequisiteFailed	Deprecated This type will be removed in a future version.
EvaluationReason.RuleMatch	Deprecated This type will be removed in a future version.
EvaluationReason.TargetMatch	Deprecated This type will be removed in a future version.
Event	Base class for all analytics events that are generated by the client.
Event.Custom	A custom event created with LDClientInterface.track(String, LDUser) or one of its overloads.
Event.FeatureRequest	An event generated by a feature flag evaluation.
Event.Identify	An event created with LDClientInterface.identify(LDUser).
Event.Index	An event created internally by the SDK to hold user data that may be referenced by multiple events.
EventProcessor.NullEventProcessor	Deprecated Use Components.noEvents().
FeatureFlagsState	A snapshot of the state of all feature flags with regard to a specific user, generated by calling LDClientInterface.allFlagsState(LDUser, FlagsStateOption...).
FeatureStoreCacheConfig	Deprecated This has been superseded by the PersistentDataStoreBuilder interface.
FlagsStateOption	Optional parameters that can be passed to LDClientInterface.allFlagsState(LDUser, FlagsStateOption...).
InMemoryFeatureStore	A thread-safe, versioned store for feature flags and related data based on a HashMap.
LDClient	A client for the LaunchDarkly API.
LDConfig	This class exposes advanced configuration options for the LDClient.
LDConfig.Builder	A builder that helps construct LDConfig objects.
LDUser	A LDUser object contains specific attributes of a user browsing your site.
LDUser.Builder	A builder that helps construct LDUser objects.
RedisFeatureStore	Deprecated Use Redis.dataStore()
RedisFeatureStoreBuilder	Deprecated Use Redis.dataStore()
SegmentRule	Deprecated This class was made public in error and will be removed in a future release.
TestFeatureStore	Deprecated Will be replaced by a file-based test fixture.
UpdateProcessor.NullUpdateProcessor	Deprecated Use Components.externalUpdatesOnly() instead of referring to this implementation class directly.
VersionedDataKind<T extends VersionedData>	The descriptor for a specific kind of VersionedData objects that may exist in a FeatureStore.

Enum Summary

Enum	Description
EvaluationReason.ErrorKind	Enumerated type defining the possible values of EvaluationReason.Error.getErrorKind().
EvaluationReason.Kind	Enumerated type defining the possible values of EvaluationReason.getKind().
FeatureStoreCacheConfig.StaleValuesPolicy	Possible values for FeatureStoreCacheConfig.staleValuesPolicy(StaleValuesPolicy).
LDCountryCode	Deprecated

Package com.launchdarkly.client Description

The main package for the LaunchDarkly Java SDK.

You will most often use LDClient (the SDK client), LDConfig (configuration options for the client), and LDUser (user properties for feature flag evaluation).
