Method Detail
-
getWriteTime
public final long getWriteTime()
Description copied from class:Node
Returns the time that this entry was last written, in ns.- Overrides:
getWriteTime
in classNode<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 classNode<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 classNode<K,V>
-
newNode
public Node<K,V> newNode(K key, java.lang.ref.ReferenceQueue<K> keyReferenceQueue, V value, java.lang.ref.ReferenceQueue<V> valueReferenceQueue, int weight, long now)
Description copied from interface:NodeFactory
Returns a node optimized for the specified features.
