RecognitionException

The root of the ANTLR exception hierarchy. In general, ANTLR tracks just 3 kinds of errors: prediction errors, failed predicate errors, and mismatched input errors. In each case, the parser knows where it is in the input, where it is in the ATN, the rule invocation stack, and what kind of problem occurred.

Functions

getCtx RuleContext getCtx(): Gets the {@link RuleContext} at the time this exception was thrown.
getExpectedTokens IntervalSet getExpectedTokens(): Gets the set of input symbols which could potentially follow the previously matched symbol at the time this exception was thrown.
getInputStream IntStream getInputStream(): Undocumented in source. Be warned that the author may not have intended to support it.
getOffendingState int getOffendingState(): Get the ATN state number the parser was in at the time the error occurred. For {@link NoViableAltException} and {@link LexerNoViableAltException} exceptions, this is the {@link DecisionState} number. For others, it is the state whose outgoing edge we couldn't match.
getOffendingToken Token getOffendingToken(): Undocumented in source. Be warned that the author may not have intended to support it.
getRecognizer InterfaceRecognizer getRecognizer(): Gets the {@link Recognizer} where this exception occurred.
setOffendingState void setOffendingState(int offendingState): Undocumented in source. Be warned that the author may not have intended to support it.
setOffendingToken void setOffendingToken(Token offendingToken): Undocumented in source. Be warned that the author may not have intended to support it.

Variables
