Interface MediaList

public interface MediaList

The MediaList interface provides the abstraction of an ordered collection of media, without defining or constraining how this collection is implemented. An empty list is the same as a list that contains the medium "all".

The items in the MediaList are accessible via an integral index, starting from 0.

See also the Document Object Model (DOM) Level 2 Style Specification.

Since:
1.4, DOM Level 2
