Known indirect subclasses [Attributes2](https://developer.android.com/reference/org/xml/sax/ext/Attributes2), [Attributes2Impl](https://developer.android.com/reference/org/xml/sax/ext/Attributes2Impl), [AttributesImpl](https://developer.android.com/reference/org/xml/sax/helpers/AttributesImpl), [Driver](https://developer.android.com/reference/org/xmlpull/v1/sax2/Driver) [Attributes2](https://developer.android.com/reference/org/xml/sax/ext/Attributes2) SAX2 extension to augment the per-attribute information provided though `https://developer.android.com/reference/org/xml/sax/Attributes`. [Attributes2Impl](https://developer.android.com/reference/org/xml/sax/ext/Attributes2Impl) SAX2 extension helper for additional Attributes information, implementing the `https://developer.android.com/reference/org/xml/sax/ext/Attributes2` interface. [AttributesImpl](https://developer.android.com/reference/org/xml/sax/helpers/AttributesImpl) Default implementation of the Attributes interface. [Driver](https://developer.android.com/reference/org/xmlpull/v1/sax2/Driver) SAX2 Driver that pulls events from XmlPullParser and converts them into SAX2 callbacks.   

*** ** * ** ***

Interface for a list of XML attributes.

> *This module, both source code and documentation, is in the
> Public Domain, and comes with **NO WARRANTY**.* See <http://www.saxproject.org> for further information.

This interface allows access to a list of attributes in
three different ways:

1. by attribute index;
2. by Namespace-qualified name; or
3. by qualified (prefixed) name.

The list will not contain attributes that were declared
#IMPLIED but not specified in the start tag. It will also not
contain attributes used as Namespace declarations (xmlns\*) unless
the `http://xml.org/sax/features/namespace-prefixes`
feature is set to <var translate="no">true</var> (it is <var translate="no">false</var> by
default).
Because SAX2 conforms to the original "Namespaces in XML"
recommendation, it normally does not
give namespace declaration attributes a namespace URI.

Some SAX2 parsers may support using an optional feature flag
(`http://xml.org/sax/features/xmlns-uris`) to request
that those attributes be given URIs, conforming to a later
backwards-incompatible revision of that recommendation. (The
attribute's "local name" will be the prefix, or "xmlns" when
defining a default element namespace.) For portability, handler
code should always resolve that conflict, rather than requiring
parsers that can change the setting of that feature flag.

If the namespace-prefixes feature (see above) is
<var translate="no">false</var>, access by qualified name may not be available; if
the `http://xml.org/sax/features/namespaces` feature is
<var translate="no">false</var>, access by Namespace-qualified names may not be
available.

This interface replaces the now-deprecated SAX1 `https://developer.android.com/reference/org/xml/sax/AttributeList` interface, which does not
contain Namespace support. In addition to Namespace support, it
adds the <var translate="no">getIndex</var> methods (below).

The order of attributes in the list is unspecified, and will
vary from implementation to implementation.

### getType

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public abstract String getType (int index)
```

Look up an attribute's type by index.

The attribute type is one of the strings "CDATA", "ID",
"IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES",
or "NOTATION" (always in upper case).

If the parser has not read a declaration for the attribute,
or if the parser does not report attribute types, then it must
return the value "CDATA" as stated in the XML 1.0 Recommendation
(clause 3.3.3, "Attribute-Value Normalization").

For an enumerated attribute that is not a notation, the
parser will report the type as "NMTOKEN".
