ANTLRErrorListener
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).

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
- The line number in the input where the error occurred.charPositionInLine
- The character position within that line where the error occurred.msg
- The message to emit.e
- 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.Copyright © 1992-2016 ANTLR. All Rights Reserved.
