public class AttributesImpl extends Object implements 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 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:
startElement
event; orThis 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.

public AttributesImpl()
public AttributesImpl(Attributes atts)
This constructor is especially useful inside a
startElement
event.

In many cases, it will be more efficient to look up the name once and use the index query methods rather than using the name query methods repeatedly.
