Method Detail

getWriteTime

public final long getWriteTime()

Description copied from interface: Node

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

setWriteTime

public final void setWriteTime(long writeTime)

Description copied from interface: Node

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

getPreviousInWriteOrder

public final Node<K,V> getPreviousInWriteOrder()

Description copied from interface: WriteOrderDeque.WriteOrder

Retrieves the previous element or null if either the element is unlinked or the first element on the deque.

setPreviousInWriteOrder

public final void setPreviousInWriteOrder(Node<K,V> previousInWriteOrder)

Description copied from interface: WriteOrderDeque.WriteOrder

Sets the previous element or null if there is no link.

getNextInWriteOrder

public final Node<K,V> getNextInWriteOrder()

Description copied from interface: WriteOrderDeque.WriteOrder

Retrieves the next element or null if either the element is unlinked or the last element on the deque.

setNextInWriteOrder

public final void setNextInWriteOrder(Node<K,V> nextInWriteOrder)

Description copied from interface: WriteOrderDeque.WriteOrder

Sets the next element or null if there is no link.
