error

public void error(String domain, String key, XMLParseException exception)
Reports an error. Errors are non-fatal and usually signify that the document is invalid with respect to its grammar(s).

Parameters: domain The domain of the error. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this error. key The error key. This key can be any string and is implementation dependent. exception Exception.

Throws: XNIException Thrown to signal that the parser should stop parsing the document.

fatalError

public void fatalError(String domain, String key, XMLParseException exception)
Report a fatal error. Fatal errors usually occur when the document is not well-formed and signifies that the parser cannot continue normal operation.

Note: The error handler should always throw an XNIException from this method. This exception can either be the same exception that is passed as a parameter to the method or a new XNI exception object. If the registered error handler fails to throw an exception, the continuing operation of the parser is undetermined.

Parameters: domain The domain of the fatal error. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this fatal error. key The fatal error key. This key can be any string and is implementation dependent. exception Exception.

Throws: XNIException Thrown to signal that the parser should stop parsing the document.

getErrorHandler

public ErrorHandler getErrorHandler()
Returns the SAX error handler.

setErrorHandler

public void setErrorHandler(ErrorHandler errorHandler)
Sets the SAX error handler.

warning

public void warning(String domain, String key, XMLParseException exception)
Reports a warning. Warnings are non-fatal and can be safely ignored by most applications.

Parameters: domain The domain of the warning. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this warning. key The warning key. This key can be any string and is implementation dependent. exception Exception.

Throws: XNIException Thrown to signal that the parser should stop parsing the document.
