Methods

map<S>(S callback(int index, T value), [DataType<S>? dataType]) → Vector<S>

Available on Vector<T>, provided by the TransformedVectorExtension extension

Returns a read-only view on this Vector with all its elements lazily converted by calling the provided transformation callback.

transform<S>(S read(int index, T value), {T write(int index, S value)?, DataType<S>? dataType}) → Vector<S>

Available on Vector<T>, provided by the TransformedVectorExtension extension

Returns a view on this Vector with all its elements lazily converted by calling the provided read transformation. An optionally provided write transformation enables writing to the returned vector.
