RecognitionException<StreamType extends IntStream> class

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.

RecognitionException(Recognizer<ATNSimulator>? recognizer, StreamType inputStream, RuleContext? ctx, [String message = ''])

Properties

ctx RuleContext?
Gets the RuleContext at the time this exception was thrown.
final
expectedTokens IntervalSet?
Gets the set of input symbols which could potentially follow the previously matched symbol at the time this exception was thrown.
no setter
hashCode int
The hash code for this object.
no setterinherited
inputStream → StreamType
Gets the input stream which is the symbol source for the recognizer where this exception was thrown.
final
message String
finalinherited
offendingState int
Get the ATN state number the parser was in at the time the error occurred. For NoViableAltException and LexerNoViableAltException exceptions, this is the DecisionState number. For others, it is the state whose outgoing edge we couldn't match.
getter/setter pair
offendingToken Token
The current Token when an error occurred. Since not all streams support accessing symbols by index, we have to track the Token instance itself.
getter/setter pair
recognizer Recognizer<ATNSimulator>?
Gets the Recognizer where this exception occurred.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
stackTrace StackTrace?
The stack trace at the point where this error was first thrown.
no setterinherited
