Method Detail

getOrComputeIfAbsent

public Store.ValueHolder<V> getOrComputeIfAbsent(K key,
                                                 Function<K,Store.ValueHolder<V>> source)
                                          throws CacheAccessException

Description copied from interface: CachingTier

Either return the value holder currently in the caching tier, or compute and store it when it isn't present. Note that in case of expired value holders null will be returned and the mapping will be invalidated.

Specified by:

getOrComputeIfAbsent in interface CachingTier<K,V>

Parameters:

key - the key.

source - the function that computes the value.

Returns:

the value holder, or null.

Throws:

CacheAccessException

invalidate

public void invalidate(K key)
                throws CacheAccessException

Description copied from interface: CachingTier

Remove a mapping.

Specified by:

invalidate in interface CachingTier<K,V>

Parameters:

key - the key.

Throws:

CacheAccessException

invalidate

public void invalidate(K key,
                       NullaryFunction<K> function)
                throws CacheAccessException

Description copied from interface: CachingTier

Remove a mapping, then call a function under the same lock scope irrespectively of a mapping being there or not.

Specified by:

invalidate in interface CachingTier<K,V>

Parameters:

key - the key.

function - the function to call.

Throws:

CacheAccessException

clear

public void clear()
           throws CacheAccessException

setInvalidationListener

public void setInvalidationListener(CachingTier.InvalidationListener<K,V> invalidationListener)

Description copied from interface: CachingTier

Set the caching tier's invalidation listener. The invalidation listener can only be set once.

Specified by:

setInvalidationListener in interface CachingTier<K,V>

Parameters:

invalidationListener - the listener.
