Attributes
Attributes2Impl
public interface Attributes2 extends Attributes
Attributes
. If an implementation supports this extension, the attributes provided in ContentHandler.startElement()
will implement this interface, and the http://xml.org/sax/features/use-attributes2 feature flag will have the value true. XMLReader implementations are not required to support this information, and it is not part of core-only SAX2 distributions.
Note that if an attribute was defaulted (!isSpecified()) it will of necessity also have been declared (isDeclared()) in the DTD. Similarly if an attribute's type is anything except CDATA, then it must have been declared.

boolean isDeclared(int index)
index
- The attribute index (zero-based).ArrayIndexOutOfBoundsException
- When the supplied index does not identify an attribute.boolean isDeclared(String qName)
qName
- The XML qualified (prefixed) name.IllegalArgumentException
- When the supplied name does not identify an attribute.boolean isDeclared(String uri, String localName)
Remember that since DTDs do not "understand" namespaces, the namespace URI associated with an attribute may not have come from the DTD. The declaration will have applied to the attribute's qName.
uri
- The Namespace URI, or the empty string if the name has no Namespace URI.localName
- The attribute's local name.IllegalArgumentException
- When the supplied names do not identify an attribute.boolean isSpecified(int index)

- The attribute index (zero-based).ArrayIndexOutOfBoundsException
- When the supplied index does not identify an attribute.boolean isSpecified(String uri, String localName)
