public enum Terminal
extension Terminal: ExpressibleByStringLiteral
extension Terminal: Hashable
extension Terminal: CustomStringConvertible
extension Terminal: Codable

A terminal symbol which can occur in a string recognized by a parser and which cannot be replaced by any production

  • A terminal that is a string. The terminal is matched when the tokenized subsequence of a word is equal to this string.

    Declaration

    case string(string: String, hash: Int)

  • A terminal that is a range of characters. The terminal is matched when the tokenized subsequence is a character contained in this range.

    Declaration

    Swift

    case characterRange(range: ClosedRange<Character>, hash: Int)

  • A terminal that is a regular epxression. The terminal is matched when the tokenized subsequence is contained in the language generated by the given regular expression

    Declaration

    Swift

    case regularExpression(expression: NSRegularExpression, hash: Int)

  • Creates a terminal that is a string. The terminal is matched when the tokenized subsequence of a word is equal to this string.

    Declaration

    Swift

    init(string: String)
