public interface Attributes2
SAX2 extension to augment the per-attribute information
provided though 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.
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.
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.

Method Detail |

boolean isDeclared(int index)
index
- The attribute index (zero-based).
java.lang.ArrayIndexOutOfBoundsException
- When the
supplied index does not identify an attribute.boolean isDeclared(java.lang.String qName)
qName
- The XML qualified (prefixed) name.
java.lang.IllegalArgumentException
- When the
supplied name does not identify an attribute.boolean isDeclared(java.lang.String uri, java.lang.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.
java.lang.IllegalArgumentException
- When the
supplied names do not identify an attribute.boolean isSpecified(int index)
index
- The attribute index (zero-based).
java.lang.ArrayIndexOutOfBoundsException
- When the
supplied index does not identify an attribute.boolean isSpecified(java.lang.String uri, java.lang.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.
java.lang.IllegalArgumentException
- When the
supplied names do not identify an attribute.boolean isSpecified(java.lang.String qName)
qName
- The XML qualified (prefixed) name.
java.lang.IllegalArgumentException
- When the
supplied name does not identify an attribute.
