Description
This array type is used to define a dom::Array whose members are evaluated on demand as they are accessed.
Each member can goes through a transform function before being returned as a Value so that all types can be converted to dom::Value.
The underlying representation of the array is a range from where the elements are extracted. Elements in this range should be convertible to dom::Value.
This class is typically useful for implementing arrays that are expensive and have recursive dependencies, as these recursive dependencies can also be deferred.
Unlike a LazyObjectImpl, which contains an overlay object, this implementation is read‐only. The set and emplace_back methods are not implemented.
