Method Detail

peek

InternalCacheEntry<K,V> peek(Object key)

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.

Parameters:

key - The key to find the value for

Returns:

The value mapping to this key

touchKey

boolean touchKey(Object key,
                 long currentTimeMillis)

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

Parameters:

key - key to touch

currentTimeMillis - the recency timestamp to set

Returns:

whether the entry was touched or not
