public class NormalProduction extends Expansion
Describes JavaCC productions.

  • Field Details

    • parents

      private final List<Expansion> parents
      The NonTerminal nodes which refer to this production.

    • accessMod

      private String accessMod
      The access modifier of this production.

    • lhs

      private String lhs
      The name of the non-terminal of this production.

    • return_type_tokens

      private final List<Token> return_type_tokens
      The tokens that make up the return type of this production.

    • parameter_list_tokens

      private final List<Token> parameter_list_tokens
      The tokens that make up the parameters of this production.

    • throws_list

      private List<List<Token>> throws_list
      Each entry in this list is a list of tokens that represents an exception in the throws list of this production. This list does not include ParseException which is always thrown.

    • expansion

      private Expansion expansion
      The RHS of this production. Not used for JavaCodeProduction.

    • emptyPossible

      private boolean emptyPossible
      This boolean flag is true if this production can expand to empty.

    • leftExpansions

      private NormalProduction[] leftExpansions
      A list of all non-terminals that this one can expand to without having to consume any tokens. Also an index that shows how many pointers exist.

    • leIndex

      int leIndex

    • walkStatus

      private int walkStatus
      The following variable is used to maintain state information for the left-recursion determination algorithm: It is initialized to 0, and set to -1 if this node has been visited in a pre-order walk, and then it is set to 1 if the pre-order walk of the whole graph from this node has been traversed. i.e., -1 indicates partially processed, and 1 indicates fully processed.

    • lastToken

      private Token lastToken
      The first and last tokens from the input stream that represent this production.

    • firstToken

      private Token firstToken

    • eol

      private final String eol
