Hello to all!.
i'm creating a job that consist in a series of orders for printing. the job manager is very simple with only the delete option ( to delete one entry ) and the swap option ( to swap entry up or down).
i had though to use a linked list and after searching i've tried to use the collectionExtra library which by the way is for android but i've also worked with it in b4j.
however... when i debug i see what it seens to be 2 methods that are not public (but are usually used in linked list ). they are Next and Prev.
So my question is:
using the for each or for..next and inside get is the only method to read the list?
what if beeing in a element i would need to go to the next element ( without using the index of the cycle?)
shell i need to always know the item where i am?
Thank to all!
