ListNodes[A: A, N: ListNode[A] #read]

[Source]

Iterate over the nodes in a List.

class ref ListNodes[A: A, N: ListNode[A] #read] is
  Iterator[N] ref

Implements

• Iterator[N] ref

---

Constructors

create

[Source]

Build the iterator over nodes.

reverse of false iterates forward, while reverse of true iterates in reverse.

new ref create(
  head: (N | None val),
  reverse: Bool val = false)
: ListNodes[A, N] ref^

Parameters

• head: (N | None val)
• reverse: Bool val = false

Returns

• ListNodes[A, N] ref^

---

Public Functions

has_next

[Source]

Indicates whether there are any nodes remaining in the iterator.

fun box has_next()
: Bool val

Returns

• Bool val

---

next

[Source]

Return the next node in the iterator, advancing the iterator by one element.

Order of return is determined by reverse argument during creation.

fun ref next()
: N ?

Returns

• N ?
