* This list implementation can help to keep two lists in sync - like real models and view models. |
||||
* Every operation on the main list triggers update of the supplementary list (but not vice versa). |
||||
* This makes sure that the main list is always the source of truth. |
||||
* Main list is projected to the supplementary list by the passed mapper function. |
||||
* Paired list is newer actually exposed and clients are provided with {@code getPairedCopy()}, |
||||
* {@code getPairedItem()} and {@code setPairedItem()}. This prevents modifications of the |
||||
* supplementary list size so lists are always have the same length. |
||||
* This implementation will not try to recover from exceptional cases so lists may be out of sync |
||||
* after the exception. |
||||
* |
||||
* It is most useful with immutable data because we cannot track changes inside stored objects. |
