Iterate over the nodes in a List.

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

• Iterator[N] ref

[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^

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

• ListNodes[A, N] ref^

[Source]

Indicates whether there are any nodes remaining in the iterator.

fun box has_next()
: Bool val

• Bool val

[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 ?

• N ?
