Adapts source
to be a List<T>
.
Any time the list would produce an element that is not a T
, the element access will throw.
Any time a T
value is attempted stored into the adapted list, the store will throw unless the value is also an instance of S
.
If all accessed elements of source
are actually instances of T
, and if all elements stored into the returned list are actually instance of S
, then the returned list can be used as a List<T>
.
static List<T> castFrom<S, T>(List<S> source) => new CastList<S, T>(source);
