        The access modifier of this production.

      • lhs

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

      • return_type_tokens

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

      • parameter_list_tokens

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

      • throws_list

        private java.util.List<java.util.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 java.lang.String eol
