6.87 Link
- Defined in namespace Smalltalk
- Category: Collections-Sequenceable
- I represent simple linked lists. Generally, I am not used by myself, but
rather a subclass adds other instance variables that hold the information
for each node, and I hold the glue that keeps them together.
6.87.1 Link class: instance creation
- nextLink: aLink
- Create an instance with the given next link
6.87.2 Link: basic
- nextLink
- Answer the next item in the list
- nextLink: aLink
- Set the next item in the list
6.87.3 Link: iteration
- at: index
- Retrieve a node (instance of Link) that is at a distance of `index' after the receiver.
- at: index put: object
- This method should not be called for instances of this class.
- do: aBlock
- Evaluate aBlock for each element in the list
- size
- Answer the number of elements in the list. Warning: this is O(n)
