Documentation

Overview

Package glist provides a concurrent-safe/unsafe doubly linked list.

Example (Basic)

package main

import (
	"fmt"

	"github.com/snail007/gf/container/glist"
)

func main() {
	n := 10
	l := glist.New()
	for i := 0; i < n; i++ {
		l.PushBack(i)
	}
	fmt.Println(l.Len())
	fmt.Println(l.FrontAll())
	fmt.Println(l.BackAll())
	for i := 0; i < n; i++ {
		fmt.Print(l.PopFront())
	}
	l.Clear()
	fmt.Println()
	fmt.Println(l.Len())

}

Output:

10
[0 1 2 3 4 5 6 7 8 9]
[9 8 7 6 5 4 3 2 1 0]
0123456789

Types

type Element

type Element = list.Element

type List

type List struct {
	// contains filtered or unexported fields
}

func New

func New(safe ...bool) *List

New creates and returns a new empty doubly linked list.

func (*List) Back

func (l *List) Back() (e *Element)

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

func (*List) BackAll

func (l *List) BackAll() (values []interface{})

BackAll copies and returns values of all elements from back of <l> as slice.

func (*List) BackValue

func (l *List) BackValue() (value interface{})

BackValue returns value of the last element of <l> or nil if the list is empty.

func (*List) Clear

func (l *List) Clear()

See RemoveAll().

func (*List) Front

func (l *List) Front() (e *Element)

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

func (*List) FrontAll

func (l *List) FrontAll() (values []interface{})

FrontAll copies and returns values of all elements from front of <l> as slice.

func (*List) FrontValue

func (l *List) FrontValue() (value interface{})

FrontValue returns value of the first element of <l> or nil if the list is empty.

func (*List) InsertAfter

func (l *List) InsertAfter(v interface{}, p *Element) (e *Element)

InsertAfter inserts a new element <e> with value <v> immediately after <p> and returns <e>. If <p> is not an element of <l>, the list is not modified. The <p> must not be nil.

func (*List) InsertBefore

func (l *List) InsertBefore(v interface{}, p *Element) (e *Element)

InsertBefore inserts a new element <e> with value <v> immediately before <p> and returns <e>. If <p> is not an element of <l>, the list is not modified. The <p> must not be nil.

func (*List) Iterator

func (l *List) Iterator(f func(e *Element) bool)

Iterator is alias of IteratorAsc.

func (*List) IteratorAsc

func (l *List) IteratorAsc(f func(e *Element) bool)

IteratorAsc iterates the list in ascending order with given callback function <f>. If <f> returns true, then it continues iterating; or false to stop.

func (*List) IteratorDesc

func (l *List) IteratorDesc(f func(e *Element) bool)

IteratorDesc iterates the list in descending order with given callback function <f>. If <f> returns true, then it continues iterating; or false to stop.

func (*List) Len

func (l *List) Len() (length int)

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

func (*List) LockFunc

func (l *List) LockFunc(f func(list *list.List))

LockFunc locks writing with given callback function <f> within RWMutex.Lock.

func (*List) MarshalJSON

func (l *List) MarshalJSON() ([]byte, error)

MarshalJSON implements the interface MarshalJSON for json.Marshal.

func (*List) MoveAfter

func (l *List) MoveAfter(e, p *Element)

MoveAfter moves element <e> to its new position after <p>. If <e> or <p> is not an element of <l>, or <e> == <p>, the list is not modified. The element and <p> must not be nil.

func (*List) MoveBefore

func (l *List) MoveBefore(e, p *Element)

MoveBefore moves element <e> to its new position before <p>. If <e> or <p> is not an element of <l>, or <e> == <p>, the list is not modified. The element and <p> must not be nil.

func (*List) MoveToBack

func (l *List) MoveToBack(e *Element)
