    • Method Detail

      • nud

        public Term nud​(OPParser p)
        Process this token in the context of parser p with the null denotation. A nud method typically will have no interest in the token to the left. The processing results in an Abstract Syntax Tree Node that captures the meaning
        Overrides:
        nud in class OPToken
        Parameters:
        p - the parser that is the context for parsing
        Returns:
        an AstNode
      • led

        public Term led​(OPParser parser,
                        Term leftNode)
        Process this token and possibly the given leftNodein the context of a parser with the left denotation. A led method typically will be interested t in the token to the left. The processing results in an Abstract Syntax Tree Node that captures the meaning
        Overrides:
        led in class OPToken
        Parameters:
        parser - the parser that is the context for parsing
        leftNode - an ast Term that the token is possibly interested in
        Returns:
        an AstNode
      • toString

        public String toString()
        Return a human-readable description for this token.
        Overrides:
        toString in class OPToken
        Returns:
        a String description of the token
