Interface Attributes2
- Attributes
- Attributes2Impl, SAXDriver, SAXParser
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.

isDeclared
public boolean isDeclared(int index)
Returns false unless the attribute was declared in the DTD.
This helps distinguish two kinds of attributes that SAX reports
as CDATA: ones that were declared (and hence are usually valid),
and those that were not (and which are never valid).
index - The attribute index (zero-based).
- true if the attribute was declared in the DTD,
false otherwise.
isDeclared
public boolean isDeclared(String qName)
Returns false unless the attribute was declared in the DTD.
This helps distinguish two kinds of attributes that SAX reports
as CDATA: ones that were declared (and hence are usually valid),
and those that were not (and which are never valid).
qName - The XML qualified (prefixed) name.
- true if the attribute was declared in the DTD,
false otherwise.

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.
- true if the attribute was declared in the DTD,
false otherwise.
isSpecified
public boolean isSpecified(int index)
Returns true unless the attribute value was provided
by DTD defaulting.
index - The attribute index (zero-based).
- true if the value was found in the XML text,
false if the value was provided by DTD defaulting.
isSpecified
public boolean isSpecified(String qName)
Returns true unless the attribute value was provided
by DTD defaulting.
qName - The XML qualified (prefixed) name.
- true if the value was found in the XML text,
false if the value was provided by DTD defaulting.
