DoublyLinkedAggregate S

aggcat.spad line 1251 [edit on github]

• S: Type

A doubly-linked aggregate serves as a model for a doubly-linked list, that is, a list which has links to both next and previous nodes and thus can be efficiently traversed in both directions.

setnext!(u, v) destructively sets the next node of doubly-linked aggregate u to v, returning v.
