isTerminal

public boolean isTerminal()

Description copied from interface: NotificationQueue.Notification

Terminal notifications guarantee that they will not queue additional notifications or mutate data structures that should result in additional notifications. They are in turn guaranteed to be called after all non-terminal notifications for a given cycle through the notification queue.

Specified by:

True iff this notification is terminal.

getNext

setNext

public void setNext(@NotNull NotificationQueue.Notification other)

Description copied from interface: IntrusiveDoublyLinkedNode

getPrev

@NotNull public NotificationQueue.Notification getPrev()

Description copied from interface: IntrusiveDoublyLinkedNode

Specified by:

getPrev in interface IntrusiveDoublyLinkedNode<NotificationQueue.Notification>

Returns:

This node's previous node

setPrev

public void setPrev(@NotNull NotificationQueue.Notification other)

Description copied from interface: IntrusiveDoublyLinkedNode
