Class ListOpToken

  • All Implemented Interfaces:
    Cloneable

    public class ListOpToken
    extends NestingOPToken
    ListOPToken is used to process expressions between bracketing characters such as are between "[" and "]" which should result in a list (e.g. [1,3,4,5]). This class does nothing to limit nesting hence nested lists are possible.

      • 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
