Method Detail

fill

public V fill(K key,
              V value)

Description copied from class: AbstractConcurrentOffHeapMap

See OffHeapHashMap.fill(Object, Object) for a detailed description.

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:

the previous value associated with key, or null if there was no mapping for key (irrespective of whether the value was successfully installed).

                   V value)

Specified by:

putPinned in interface PinnableCache<K,V>

isPinned

public boolean isPinned(Object key)

Specified by:

isPinned in interface PinnableCache<K,V>

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
