Describes regular expressions.
  • Field Details

    • label

      public String label
      The label of the regular expression (if any). If no label is present, this is set to "".
    • lhsTokens

      public List<Token> lhsTokens
      The LHS to which the token value of the regular expression is assigned. In case there is no LHS, then the list remains empty.
    • rhsToken

      public Token rhsToken
      We now allow qualified access to token members. Store it here.
    • private_rexp

      public boolean private_rexp
      This flag is set if the regular expression has a label prefixed with the # symbol - this indicates that the purpose of the regular expression is solely for defining other regular expressions.
    • tpContext

      public TokenProduction tpContext
      If this is a top-level regular expression (nested directly within a TokenProduction), then this field point to that TokenProduction object.
