Interface NodeList

All Known Implementing Classes:
IIOMetadataNode
public interface NodeList

The NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. NodeList objects in the DOM are live.

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

See also the Document Object Model (DOM) Level 3 Core Specification.
