castFrom<S, T> static method
Adapts source
to be a ObservableList<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 ObservableList<T>
.
Implementation
static ObservableList<T> castFrom<S, T>(ObservableList<S> source) =>
ObservableList<T>._spy(source._list.cast<T>());
