DOMImplementationList
Stay organized with collections
Save and categorize content based on your preferences.
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.
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.
