CollectiveListDeputy<E> class

A helper class that provides an "deputy" (deputy) interface for CollectiveList.

This class extends CollectiveList and mixes in Deputy functionality to create a wrapper that can modify behavior while delegating operations to the original list. It's particularly useful for adding temporary modifications like additional validation rules or value transformations.

The deputy maintains a reference to the original list and can apply:

  • Additional test rules (validation)
  • Value mapping transformations
  • Other behavior modifications

Example:

final originalList = CollectiveList<int>();
final deputy = originalList.deputy(
  test: customTestRules,
  map: valueMapper
);
