Overrides:

fill in class AbstractConcurrentOffHeapMap<K,V>

Parameters:

key - key with which the specified value is to be associated

value - value to be associated with the specified key

Returns:

setPinning

public void setPinning(K key,
 boolean pinned)

Specified by:

setPinning in interface PinnableCache<K,V>

segmentFor

protected PinnableSegment<K,V> segmentFor(Object key)

Overrides:

segmentFor in class AbstractConcurrentOffHeapMap<K,V>

shrink

public boolean shrink()

shrinkOthers
