- org.xml.sax.helpers.AttributesImpl

All Implemented Interfaces:

Attributes

Direct Known Subclasses:

Attributes2Impl
```
public class AttributesImpl
extends Object
implements Attributes
```
Default implementation of the Attributes interface.
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 class provides a default implementation of the SAX2 Attributes interface, with the addition of manipulators so that the list can be modified or reused.

There are two typical uses of this class:
1. to take a persistent snapshot of an Attributes object in a startElement event; or
2. to construct or modify an Attributes object in a SAX2 driver or filter.
This class replaces the now-deprecated SAX1 AttributeListImpl class; in addition to supporting the updated Attributes interface rather than the deprecated AttributeList interface, it also includes a much more efficient implementation using a single array rather than a set of Vectors.
Since:

SAX 2.0

```
    Add an attribute to the end of the list.
    For the sake of speed, this method does no checking to see if the attribute is already in the list: that is the responsibility of the application.

                String value)
```
    Set an attribute in the list.
