Package list

Overview

Package list implements a doubly linked list.

To iterate over a list (where l is a *List):

for e := l.Front(); e != nil; e = e.Next() {
	// do something with e.Value
}

Example

package main

import (
	"container/list"
	"fmt"
)

func main() {
	// Create a new list and put some numbers in it.
	l := list.New()
	e4 := l.PushBack(4)
	e1 := l.PushFront(1)
	l.InsertBefore(3, e4)
	l.InsertAfter(2, e1)

	// Iterate through list and print its contents.
	for e := l.Front(); e != nil; e = e.Next() {
		fmt.Println(e.Value)
	}

}

type ElementSource

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 (*Element) NextSource

func (e *Element) Next() *Element

Next returns the next list element or nil.

func (*Element) PrevSource

func (e *Element) Prev() *Element

Prev returns the previous list element or nil.

type ListSource

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 NewSource

func New() *List

New returns an initialized list.

func (*List) BackSource

func (l *List) Back() *Element

Back returns the last element of list l or nil if the list is empty.

func (*List) FrontSource

func (l *List) Front() *Element

Front returns the first element of list l or nil if the list is empty.

func (*List) InitSource

func (l *List) Init() *List

Init initializes or clears list l.

func (*List) InsertAfterSource

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 (*List) InsertBeforeSource

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 (*List) LenSource

func (l *List) Len() int

Len returns the number of elements of list l. The complexity is O(1).

func (*List) MoveAfterSource 1.2

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 (*List) MoveBeforeSource 1.2

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 (*List) MoveToBackSource

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 (*List) MoveToFrontSource

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 (*List) PushBackSource

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 (*List) PushBackListSource

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 (*List) PushFrontSource

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 (*List) PushFrontListSource

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 (*List) RemoveSource

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.
