Method Details

getWriteTime

public final long getWriteTime()

Description copied from class: Node

Returns the time that this entry was last written, in ns.

Overrides:

getWriteTime in class Node<K,V>

setWriteTime

public final void setWriteTime(long writeTime)

Description copied from class: Node

Sets the write time in nanoseconds. This update may be set lazily and rely on the memory fence when the lock is released.

Overrides:

setWriteTime in class Node<K,V>

casWriteTime

public final boolean casWriteTime(long expect,
 long update)

Description copied from class: Node

Atomically sets the write time to the given updated value if the current value equals the expected value and returns if the update was successful.

Overrides:

casWriteTime in class Node<K,V>

newNode

public Node<K,V> newNode(K key,
 ReferenceQueue<K> keyReferenceQueue,
 V value,
 ReferenceQueue<V> valueReferenceQueue,
 int weight,
 long now)

Description copied from interface: NodeFactory

Returns a node optimized for the specified features.

Specified by:

newNode in interface NodeFactory<K,V>

Overrides:

newNode in class PS<K,V>

newNode

public Node<K,V> newNode(Object keyReference,
 V value,
 ReferenceQueue<V> valueReferenceQueue,
 int weight,
 long now)

Description copied from interface: NodeFactory

Returns a node optimized for the specified features.

Specified by:

newNode in interface NodeFactory<K,V>

Overrides:

newNode in class PS<K,V>
