// getExpectedTokens computes the set of input symbols which could follow ATN
// state number stateNumber in the specified full parse context ctx and returns
// the set of potentially valid input symbols which could follow the specified
// state in the specified context. This method considers the complete parser
// context, but does not evaluate semantic predicates (i.e. all predicates
// encountered during the calculation are assumed true). If a path in the ATN
// exists from the starting state to the RuleStopState of the outermost context
// without Matching any symbols, Token.EOF is added to the returned set.
//
// A nil ctx defaults to ParserRuleContext.EMPTY.
//
// It panics if the ATN does not contain state stateNumber.
