      • kindImage

        public static final java.lang.String[] kindImage
        The image of the above constants

      • lexStates

        public java.lang.String[] lexStates
        The states in which this regular expression production exists. If this array is null, then "<*>" has been specified and this regular expression exists in all states. However, this null value is replaced by a String array that includes all lexical state names during the semanticization phase

      • kind

        public int kind
        The kind of this token production - TOKEN, SKIP, MORE, or SPECIAL

      • respecs

        public java.util.List<RegExprSpec_> respecs
        The list of regular expression specifications that comprise this production. Each entry is a "RegExprSpec"

      • isExplicit

        public boolean isExplicit
        This is true if this corresponds to a production that actually appears in the input grammar. Otherwise (if this is created to describe a regular expression that is part of the BNF) this is set to false

      • ignoreCase

        public boolean ignoreCase
        This is true if case is to be ignored within the regular expressions of this token production

      • firstToken

        public Token firstToken
        The first token from the input stream that represent this production

      • lastToken

        public Token lastToken
        The last token from the input stream that represent this production
