Method Summary

Modifier and Type	Method and Description
static <K,V> org.onosproject.store.service.AsyncConsistentMap<K,V>	newCachingMap(org.onosproject.store.service.AsyncConsistentMap<K,V> map) Creates an instance of AsyncConsistentMap that caches entries on get.
static <K,V> org.onosproject.store.service.AsyncConsistentMap<K,V>	newMeteredMap(org.onosproject.store.service.AsyncConsistentMap<K,V> map) Creates an instance of AsyncConsistentMap that records metrics for all its operations.
static <E> org.onosproject.store.service.AsyncDistributedSet<E>	newSetFromMap(org.onosproject.store.service.AsyncConsistentMap<E,Boolean> map) Creates an instance of AsyncDistributedSet that is backed by a AsyncConsistentMap.
static <K1,V1,K2,V2> org.onosproject.store.service.AsyncConsistentMap<K1,V1>	newTranscodingMap(org.onosproject.store.service.AsyncConsistentMap<K2,V2> map, Function<K1,K2> keyEncoder, Function<K2,K1> keyDecoder, Function<V1,V2> valueEncoder, Function<V2,V1> valueDecoder) Creates an instance of AsyncConsistentMap that transforms operations inputs and applies them to corresponding operation in a different typed map and returns the output after reverse transforming it.
static <K,V> org.onosproject.store.service.AsyncConsistentMap<K,V>	newUnmodifiableMap(org.onosproject.store.service.AsyncConsistentMap<K,V> map) Creates an instance of AsyncConsistentMap that disallows updates.
