A
ValidatorHandler is
an org.xml.sax.ContentHandler that uses the
streaming SAX API to validate an XML document against the
Schema from which the
ValidatorHandler was derived. The
Validator class can be used to validate a
SAXSource, but ValidatorHandler
provides lower-level access to the SAX API.
If the document is not valid, one of the
ContentHandler methods throws a
SAXException that propagates up to your code. As
with the Validator class, you can alter this by
specifying a custom org.xml.sax.ErrorHandler
class.
ValidatorHandler can be used as a filter for SAX
parsing events. If you pass a ContentHandler to
setContentHandler( ), the
ValidatorHandler augments the source document with
attribute defaults from the schema and invokes the appropriate
callback methods on the ContentHandler you supply.
If you are interested in attribute and element type information
provided by the schema, your ContentHandler can
use the TypeInfoProvider obtained from the
ValidatorHandler getTypeInfoProvider(
).
