Method Detail

delegate

protected ConcurrentMap<K,InternalCacheEntry<K,V>> delegate()

Specified by:

delegate in class AbstractDelegatingConcurrentMap<K,InternalCacheEntry<K,V>>

peek

public InternalCacheEntry<K,V> peek(Object key)

Description copied from interface: PeekableTouchableMap

Peaks at a value for the given key. Note that this does not update any expiration or eviction information when this is performed on the map, unlike the get method.

Specified by:

peek in interface PeekableTouchableMap<K,V>

Parameters:

key - The key to find the value for

Returns:

The value mapping to this key

touchKey

public boolean touchKey(Object key,
                        long currentTimeMillis)

Description copied from interface: PeekableTouchableMap

Touches the entry for the given key in this map. This method will update any recency timestamps for both expiration or eviction as needed.

Specified by:

touchKey in interface PeekableTouchableMap<K,V>

Parameters:

key - key to touch

currentTimeMillis - the recency timestamp to set

Returns:

whether the entry was touched or not
