DOMImplementationList

  • DOMImplementationList is an interface representing an ordered collection of DOM implementations, accessible by index.

  • It provides methods to get the total number of DOMImplementation objects (getLength) and retrieve a specific DOMImplementation by its index (item).

  • Indices for accessing DOMImplementation objects within the list start from 0.

  • If an invalid index is provided to the item method, it returns null.
public interface DOMImplementationList

The DOMImplementationList interface provides the abstraction of an ordered collection of DOM implementations, without defining or constraining how this collection is implemented. The items in the DOMImplementationList are accessible via an integral index, starting from 0.

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

Public Method Summary

abstract int
getLength()
The number of DOMImplementations in the list.
abstract DOMImplementation
item(int index)
Returns the indexth item in the collection.

Public Methods

public abstract int getLength ()

The number of DOMImplementations in the list. The range of valid child node indices is 0 to length-1 inclusive.

public abstract DOMImplementation item (int index)

Returns the indexth item in the collection. If index is greater than or equal to the number of DOMImplementations in the list, this returns null.

Parameters
index Index into the collection.
Returns
  • The DOMImplementation at the index th position in the DOMImplementationList, or null if that is not a valid index.
