Types

type Element

type Element struct {

	// The value stored with this element.
	Value ValueType
	// contains filtered or unexported fields
}

Element is an element of a linked list.

func (*Element) Next

func (e *Element) Next() *Element

Next returns the next list element or nil.

func (*Element) Prev

func (e *Element) Prev() *Element

Prev returns the previous list element or nil.

type ElementPool

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

ElementPool provides a pool for Elements.

type List

type List struct {
	Pool *ElementPool
	// contains filtered or unexported fields
}

List represents a doubly linked list. The zero value is an empty, ready to use list.

func (*List) Back

func (l *List) Back() *Element

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

func (*List) Front

func (l *List) Front() *Element

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

func (*List) Init

func (l *List) Init() *List

Init initializes or clears list l.

func (*List) InsertAfter

func (l *List) InsertAfter(v ValueType, 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) InsertBefore

func (l *List) InsertBefore(v ValueType, 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) Len

func (l *List) Len() int

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

func (*List) MoveAfter

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) MoveBefore

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) MoveToBack

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) MoveToFront

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) PushBack

func (l *List) PushBack(v ValueType) *Element

PushBack inserts a new element e with value v at the back of list l and returns e.

func (*List) PushBackList

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) PushFront

func (l *List) PushFront(v ValueType) *Element

PushFront inserts a new element e with value v at the front of list l and returns e.

func (*List) PushFrontList

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) Remove

func (l *List) Remove(e *Element) ValueType

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.

func (*List) Reset

func (l *List) Reset()

Reset resets list l for reuse and puts all elements back into the pool.

type ValueType

type ValueType generic.Type

ValueType is the generic element type for use with the list.
