    • 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 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.
