ruleToTokenType public property

For lexer ATNs, this maps the rule index to the resulting token type.
For lexer ATNs, this maps the rule index to the resulting token type. For parser ATNs, this maps the rule index to the generated bypass token type if the ATNDeserializationOptions.GenerateRuleBypassTransitions() deserialization option was specified; otherwise, this is .
