 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 Attributesinterface, with the addition of manipulators so that the list can be modified or reused.There are two typical uses of this class: - to take a persistent snapshot of an Attributes object
  in a startElementevent; or
- to construct or modify an Attributes object in a SAX2 driver or filter.
 This class replaces the now-deprecated SAX1 AttributeListImplclass; in addition to supporting the updated Attributes interface rather than the deprecatedAttributeListinterface, it also includes a much more efficient implementation using a single array rather than a set of Vectors.- Since:
- 1.4, SAX 2.0

- 
 - 
Method Detail-

getIndexpublic int getIndex(String uri, String localName) Look up an attribute's index by Namespace name.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. - Specified by:

- See Also:
- Attributes.getIndex(java.lang.String,java.lang.String)
 
 -

- The attribute's index, or -1 if none matches.
- See Also:
- Attributes.getIndex(java.lang.String)
 
 - 
getTypepublic String getType(String uri, String localName) Look up an attribute's type by Namespace-qualified name.- Specified by:
- getTypein interface- Attributes
- Parameters:
- uri- The Namespace URI, or the empty string for a name with no explicit Namespace URI.
- localName- The local name.
