Validator (Java Platform SE 7 ) (original) (raw)

Sets the ErrorHandler to receive errors encountered during the validate method invocation.

Error handler can be used to customize the error handling process during a validation. When an ErrorHandler is set, errors found during the validation will be first sent to the ErrorHandler.

The error handler can abort further validation immediately by throwing SAXException from the handler. Or for example it can print an error to the screen and try to continue the validation by returning normally from the ErrorHandler

If any Throwable is thrown from an ErrorHandler, the caller of the validate method will be thrown the same Throwable object.

Validator is not allowed to throw SAXException without first reporting it toErrorHandler.

When the ErrorHandler is null, the implementation will behave as if the following ErrorHandler is set:

class DraconianErrorHandler implements ErrorHandler { public void fatalError( SAXParseException e ) throws SAXException { throw e; } public void error( SAXParseException e ) throws SAXException { throw e; } public void warning( SAXParseException e ) throws SAXException { // noop } }

When a new Validator object is created, initially this field is set to null.
