com.launchdarkly.client.RedisFeatureStore

All Implemented Interfaces:

FeatureStore, java.io.Closeable, java.lang.AutoCloseable

Deprecated.

Use Redis.dataStore()

@Deprecated
public class RedisFeatureStore
extends java.lang.Object
implements FeatureStore

Deprecated implementation class for the Redis-based persistent data store.

Instead of referencing this class directly, use Redis.dataStore() to obtain a builder object.

Constructor Detail

RedisFeatureStore

protected RedisFeatureStore(RedisFeatureStoreBuilder builder)

Deprecated.

Creates a new store instance that connects to Redis based on the provided RedisFeatureStoreBuilder.

See the RedisFeatureStoreBuilder for information on available configuration options and what they do.

Parameters:

builder - the configured builder to construct the store with.

RedisFeatureStore

@Deprecated
public RedisFeatureStore()

Deprecated. Please use Components.redisFeatureStore() instead.

Creates a new store instance that connects to Redis with a default connection (localhost port 6379) and no in-memory cache.

Method Detail

init

public void init(java.util.Map<VersionedDataKind<?>,java.util.Map<java.lang.String,? extends VersionedData>> allData)

Deprecated.

Description copied from interface: FeatureStore

Initializes (or re-initializes) the store with the specified set of objects. Any existing entries will be removed. Implementations can assume that this set of objects is up to date-- there is no need to perform individual version comparisons between the existing objects and the supplied features.

If possible, the store should update the entire data set atomically. If that is not possible, it should iterate through the outer map and then the inner map in the order provided (the SDK will use a Map subclass that has a defined ordering), storing each item, and then delete any leftover items at the very end.

The store should not attempt to modify any of the Maps, and if it needs to retain the data in memory it should copy the Maps.

Specified by:

init in interface FeatureStore

Parameters:

allData - all objects to be stored

get

public <T extends VersionedData> T get(VersionedDataKind<T> kind,
                                       java.lang.String key)

Deprecated.

Description copied from interface: FeatureStore

Returns the object to which the specified key is mapped, or null if the key is not associated or the associated object has been deleted.

Specified by:

get in interface FeatureStore

Type Parameters:

T - class of the object that will be returned

Parameters:

kind - the kind of object to get

key - the key whose associated object is to be returned

Returns:

the object to which the specified key is mapped, or null if the key is not associated or the associated object has been deleted.

all

public <T extends VersionedData> java.util.Map<java.lang.String,T> all(VersionedDataKind<T> kind)

Deprecated.

Description copied from interface: FeatureStore

Returns a Map of all associated objects of a given kind.

Specified by:

all in interface FeatureStore

Type Parameters:

T - class of the objects that will be returned in the map

Parameters:

kind - the kind of objects to get

Returns:

a map of all associated object.

upsert

public <T extends VersionedData> void upsert(VersionedDataKind<T> kind,
                                             T item)

Deprecated.

Description copied from interface: FeatureStore

Update or insert the object associated with the specified key, if its version is less than or equal to the version specified in the argument object.

Specified by:

upsert in interface FeatureStore

Type Parameters:

T - class of the object to be updated

Parameters:

kind - the kind of object to update

item - the object to update or insert

delete

public <T extends VersionedData> void delete(VersionedDataKind<T> kind,
                                             java.lang.String key,
                                             int version)

Deprecated.

Description copied from interface: FeatureStore

Deletes the object associated with the specified key, if it exists and its version is less than or equal to the specified version.

Specified by:

delete in interface FeatureStore

Type Parameters:

T - class of the object to be deleted

Parameters:

kind - the kind of object to delete
