*** ** * ** ***

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](http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407).

## Public methods

### getLength

Added in[API level 8](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public abstract int getLength ()
```

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

<br />

|    Returns    ||
|-------|--------|
| `int` | <br /> |

### item

Added in[API level 8](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public abstract DOMImplementation item (int index)
```

Returns the`index`th item in the collection. If`index`is greater than or equal to the number of`DOMImplementation`s in the list, this returns`null`.
