Method Detail
-
getName
public String getName()
Description copied from interface:Cache
Returns the cache name.- Returns:
- cache name
-
get
public <K,V> io.smallrye.mutiny.Uni<V> get(K key, Function<K,V> valueLoader)
Description copied from interface:Cache
Returns a lazy asynchronous action that will emit the cache value identified bykey
, obtaining that value fromvalueLoader
if necessary.- Type Parameters:
K
- cache key typeV
- cache value type- Parameters:
key
- cache keyvalueLoader
- function used to compute a cache value ifkey
is not already associated with a value- Returns:
- a lazy asynchronous action that will emit a cache value
-
invalidate
public io.smallrye.mutiny.Uni<Void> invalidate(Object key)
Description copied from interface:Cache
Removes the cache entry identified bykey
from the cache. If the key does not identify any cache entry, nothing will happen.- Parameters:
key
- cache key
-
invalidateAll
public io.smallrye.mutiny.Uni<Void> invalidateAll()
Description copied from interface:Cache
Removes all entries from the cache.
-
replaceUniValue
public io.smallrye.mutiny.Uni<Void> replaceUniValue(Object key, Object emittedValue)
Description copied from class:AbstractCache
Replaces the cache value associated with the given key by an item emitted by aUni
. This method can be called several times for the same key, each call will then always replace the existing cache entry with the given emitted value. If the key no longer identifies a cache entry, this method must not put the emitted item into the cache.- Specified by:
replaceUniValue
