reset

public void reset()

Description copied from interface: Validator

Cleans up after validating a document. After completing validation of a document, reset must be called. After calling reset(), another document may be validated. Calling this method may create new ContentHandler and DTDHandler objects or may simply reinitialize the state of the existing objects.

Specified by:

reset in interface Validator

getContentHandler

public ContentHandler getContentHandler()

Description copied from interface: Validator

Returns the ContentHandler that will receive the XML document. Information about the XML document to be validated must be reported by calling methods on the returned ContentHandler. When validation of an XML document has been completed (either endDocument() has been called or validation has been abandoned prematurely), reset() must be called. If no calls are made on the ContentHandler, then reset() need not be called. Implementations should allocate resources that require cleanup (e.g. threads, open files) lazily, typically in startDocument(). This method does not change the state of the Validator: the same object will always be returned unless reset is called.

Specified by:

getContentHandler in interface Validator

Returns:

a ContentHandler, never null

See Also:

Validator.reset()

getDTDHandler

public DTDHandler getDTDHandler()

Description copied from interface: Validator

Returns a DTDHandler. Information about the DTD must be reported by calling methods on the returned object, unless null is returned. The same object will always be returned unless reset is called: this method does not change the state of the Validator.

Specified by:

getDTDHandler in interface Validator

Returns:

a DTDHandler, maybe null if DTD information is not significant to the Validator

error

private void error(String key,
                   String arg)
            throws SAXException

Throws:

SAXException
