Description copied from interface:ErrorHandler
Receive notification of a warning.CSS parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML 1.0 recommendation. The default behaviour is to take no action.
The CSS parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end.

warning

exception
- The warning information encapsulated in a CSS parse exception.- Throws:
CSSException
- Any CSS exception, possibly wrapping another exception.- See Also:

error
Description copied from interface:ErrorHandler
Receive notification of a recoverable error.This corresponds to the definition of "error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a validating parser would use this callback to report the violation of a validity constraint. The default behaviour is to take no action.
The CSS parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end. If the application cannot do so, then the parser should report a fatal error even if the XML 1.0 recommendation does not require it to do so.
- Specified by:
error
in interfaceErrorHandler
- Parameters:
exception
- The error information encapsulated in a CSS parse exception.- Throws:
CSSException
- Any CSS exception, possibly wrapping another exception.- See Also:
-
fatalError
Description copied from interface:ErrorHandler
Receive notification of a non-recoverable error.This corresponds to the definition of "fatal error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a parser would use this callback to report the violation of a well-formedness constraint.
The application must assume that the document is unusable after the parser has invoked this method, and should continue (if at all) only for the sake of collecting addition error messages: in fact, CSS parsers are free to stop reporting any other events once this method has been invoked.
- Specified by:
fatalError
in interfaceErrorHandler
- Parameters:
exception
- The error information encapsulated in a CSS parse exception.- Throws:
CSSException
- Any CSS exception, possibly wrapping another exception.- See Also:
