Element is an element of a linked list.
type Element struct {
// The value stored with this element.
Value interface{}
// contains filtered or unexported fields
}
func (e *Element) Next() *Element
Next returns the next list element or nil.
func (e *Element) Prev() *Element
Prev returns the previous list element or nil.
List represents a doubly linked list. The zero value for List is an empty list ready to use.
type List struct {
// contains filtered or unexported fields
}
func New() *List
New returns an initialized list.
func (l *List) Back() *Element
Back returns the last element of list l or nil if the list is empty.
func (l *List) Front() *Element
Front returns the first element of list l or nil if the list is empty.
func (l *List) Init() *List
Init initializes or clears list l.
func (l *List) InsertAfter(v interface{}, mark *Element) *Element
InsertAfter inserts a new element e with value v immediately after mark and returns e. If mark is not an element of l, the list is not modified. The mark must not be nil.
func (l *List) InsertBefore(v interface{}, mark *Element) *Element
InsertBefore inserts a new element e with value v immediately before mark and returns e. If mark is not an element of l, the list is not modified. The mark must not be nil.
func (l *List) Len() int
Len returns the number of elements of list l. The complexity is O(1).
func (l *List) MoveAfter(e, mark *Element)
MoveAfter moves element e to its new position after mark. If e or mark is not an element of l, or e == mark, the list is not modified. The element and mark must not be nil.
func (l *List) MoveBefore(e, mark *Element)
MoveBefore moves element e to its new position before mark. If e or mark is not an element of l, or e == mark, the list is not modified. The element and mark must not be nil.
func (l *List) MoveToBack(e *Element)
MoveToBack moves element e to the back of list l. If e is not an element of l, the list is not modified. The element must not be nil.
func (l *List) MoveToFront(e *Element)
MoveToFront moves element e to the front of list l. If e is not an element of l, the list is not modified. The element must not be nil.
func (l *List) PushBack(v interface{}) *Element
PushBack inserts a new element e with value v at the back of list l and returns e.
func (l *List) PushBackList(other *List)
PushBackList inserts a copy of an other list at the back of list l. The lists l and other may be the same. They must not be nil.
func (l *List) PushFront(v interface{}) *Element
PushFront inserts a new element e with value v at the front of list l and returns e.
func (l *List) PushFrontList(other *List)
PushFrontList inserts a copy of an other list at the front of list l. The lists l and other may be the same. They must not be nil.
func (l *List) Remove(e *Element) interface{}
Remove removes e from l if e is an element of list l. It returns the element value e.Value. The element must not be nil.
