# NameList

public interface **NameList** The `NameList` interface provides the abstraction of an ordered
collection of parallel pairs of name and namespace values (which could be
null values), without defining or constraining how this collection is
implemented. The items in the `NameList` 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

#### public abstract boolean
**contains**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) str)

Test if a name is part of this `NameList`.

##### Parameters

| str | The name to look for. |
|---|---|

##### Returns

- `true` if the name has been found, `false` otherwise.

#### public abstract boolean
**containsNS**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) namespaceURI, [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) name)

Test if the pair namespaceURI/name is part of this
`NameList`.

##### Parameters

| namespaceURI | The namespace URI to look for. |
| name | The name to look for. |
|---|---|

##### Returns

- `true` if the pair namespaceURI/name has been found, `false` otherwise.

#### public abstract int
**getLength**
()

The number of pairs (name and namespaceURI) in the list. The range of
valid child node indices is 0 to `length-1` inclusive.

#### public abstract [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getName**
(int index)

Returns the `index`th name item in the collection.

##### Parameters

| index | Index into the collection. |
|---|---|

##### Returns

- The name at the `index`th position in the `NameList`, or `null` if there is no name for the specified index or if the index is out of range.

#### public abstract [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getNamespaceURI**
(int index)

Returns the `index`th namespaceURI item in the collection.

##### Parameters

| index | Index into the collection. |
|---|---|

##### Returns

- The namespace URI at the `index`th position in the `NameList`, or `null` if there is no name for the specified index or if the index is out of range.
