syntaxError
public void syntaxError(Recognizer<?,?> recognizer,
Object offendingSymbol,
int line,
int charPositionInLine,
String msg,
RecognitionException e)
Upon syntax error, notify any interested parties. This is not
how to recover from errors or compute error messages. The
parser ANTLRErrorStrategy specifies how to recover from syntax
errors and how to compute error messages. This listener's job
is simply to emit a computed message, though it has enough
information to create its own message in many cases.
The RecognitionException is non-null for all syntax errors
except when we discover mismatched token errors that we can
recover from in-line, without returning from the surrounding
rule (via the single token insertion and deletion mechanism).
- Specified by:
syntaxError in interface ANTLRErrorListener- Overrides:
syntaxError in class BaseErrorListener- Parameters:
recognizer - What parser got the error. From this
object, you can access the context as well
as the input stream.offendingSymbol - The offending token in the input token
stream, unless recognizer is a lexer (then it's null) If
no viable alternative error, e has token at which we
started production for the decision.line - At what line in input to the error occur? This always refers to
stopTokenIndexcharPositionInLine - At what character position within that line did the error occur.msg - The message to emite - The exception generated by the parser that led to
the reporting of an error. It is null in the case where
the parser was able to recover in line without exiting the
surrounding rule.
