|

|

* <p>This class provides a default implementation of the SAX2
|
||||
* {@link org.xml.sax.Attributes Attributes} interface, with the
|
||||
* addition of manipulators so that the list can be modified or
|
||||
* reused.</p>
|
||||
*
|
||||
* <p>There are two typical uses of this class:</p>
|
||||
*
|
||||
* <ol>
|
||||
* <li>to take a persistent snapshot of an Attributes object
|
||||
* in a {@link org.xml.sax.ContentHandler#startElement startElement} event; or</li>
|
||||
* <li>to construct or modify an Attributes object in a SAX2 driver or filter.</li>
|
||||
* </ol>
|
||||
*
|
||||
* <p>This class replaces the now-deprecated SAX1 {@link
|
||||
* org.xml.sax.helpers.AttributeListImpl AttributeListImpl}
|
||||
* class; in addition to supporting the updated Attributes
|
||||
* interface rather than the deprecated {@link org.xml.sax.AttributeList
|
||||
* AttributeList} interface, it also includes a much more efficient
|
||||
* implementation using a single array rather than a set of Vectors.</p>
