public RefreshCache(Cache cache)

方法详细资料

close

public void close()

从接口复制的说明: Cache

Clean resources created by this cache.

指定者:

close 在接口中 Cache<K,V>

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 SimpleProxyCache<K,V>

computeIfAbsent

public V computeIfAbsent(K key,
                         Function<K,V> loader)

从接口复制的说明: Cache

If there is a value associated with the key, return the value; otherwise use the loader load the value and return, and then update the cache.

指定者:

computeIfAbsent 在接口中 Cache<K,V>

覆盖:

computeIfAbsent 在类中 SimpleProxyCache<K,V>

参数:

key - the key

loader - the value loader

返回:

the value

另请参阅:

CacheConfig.isCacheNullValue()

computeIfAbsent

public V computeIfAbsent(K key,
                         Function<K,V> loader,
                         boolean cacheNullWhenLoaderReturnNull)

从接口复制的说明: Cache

If there is a value associated with the key, return the value; otherwise use the loader load the value and return, and then update the cache.

指定者:

computeIfAbsent 在接口中 Cache<K,V>

覆盖:

computeIfAbsent 在类中 SimpleProxyCache<K,V>

参数:

key - the key

loader - the value loader

cacheNullWhenLoaderReturnNull - true if null value returned by loader should put into cache use the key

返回:

the value

computeIfAbsent

public V computeIfAbsent(K key,
                         Function<K,V> loader,
                         boolean cacheNullWhenLoaderReturnNull,
                         long expireAfterWrite,
                         TimeUnit timeUnit)

从接口复制的说明: Cache

If there is a value associated with the key, return the value; otherwise use the loader load the value and return, and then update the cache.

指定者:

computeIfAbsent 在接口中 Cache<K,V>

覆盖:

computeIfAbsent 在类中 SimpleProxyCache<K,V>

参数:

key - the key

loader - the value loader

cacheNullWhenLoaderReturnNull - true if null value returned by loader should put into cache use the key

expireAfterWrite - the TTL(time to live) of the KV association

timeUnit - the time unit of expireAfterWrite

返回:

the value

GET

public CacheGetResult<V> GET(K key)

从接口复制的说明: Cache

Gets an entry from the cache.

if the implementation supports asynchronous operation, the cache access may not completed after this method return. The invoke of getResultCode()/isSuccess()/getMessage()/getValue() on the result will block until cache operation is completed. Call future() method on the result will get a CompletionStage instance for asynchronous programming.

指定者:

GET 在接口中 Cache<K,V>

覆盖:

GET 在类中 SimpleProxyCache<K,V>

参数:

key - the key

返回:

the result

GET_ALL

public MultiGetResult<K,V> GET_ALL(Set<? extends K> keys)

从接口复制的说明: Cache

Gets a collection of entries from the Cache.

if the implementation supports asynchronous operation, the cache access may not completed after this method return. The invoke of getResultCode()/isSuccess()/getMessage()/getValue() on the result will block until cache operation is completed. Call future() method on the result will get a CompletionStage instance for asynchronous programming.

指定者:

GET_ALL 在接口中 Cache<K,V>

覆盖:

GET_ALL 在类中 SimpleProxyCache<K,V>

参数:

keys - the key collection

返回:

the result
