UndoHeader<E> class

An header with an final entry, which is doubly linked with an chain of headers, while also being doubly linked with an chain of adjacent headers, resulting in a tree like structure.

Methods

add(E entry, int i) → UndoHeader<E>
Add the entry to the current branch. If we are a head, append it, otherwise appendAlt.
altHead() → UndoHeader<E>
The head of the current alt UndoHeader linked list.
altIter() → Iterable<UndoHeader<E>>
An iterable which walks the alt UndoHeader linked list from the altTail to the altHead.
altTail() → UndoHeader<E>
The tail of the current alt UndoHeader linked list.
append(E entry, int i) → UndoHeader<E>
Append the entry to the end of the UndoHeader linked list, so that it becomes the new head.
appendAlt(E entry, int i) → UndoHeader<E>
Append the entry to the end of the alt UndoHeader linked list, so that it becomes the new altHead.
entriesIter() → Iterable<UndoHeader<E>>
An iterable which walks the UndoHeader linked list from the tail to the head, passing through this.
The head of the current UndoHeader linked list.
nextsIter() → Iterable<UndoHeader<E>>
An iterable which walks the UndoHeader linked list from this to the head.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
prevsIter() → Iterable<UndoHeader<E>>
An iterable which walks the UndoHeader linked list backwards from this to the tail.
tail() → UndoHeader<E>
The tail of the current UndoHeader linked list.
toString() → String
A string representation of this object.
