  • Constructor Details

    • ExtendedTerminalNode

      public ExtendedTerminalNode(ParserRuleContext parent, Token symbol)
      Creates a new extended terminal node with a parent node and a token as the symbol.
      Parameters:
      parent - The parent node. This is a parser rule context because the parser passes a parser rule context when it creates new terminal nodes.
      symbol - The token to contain with this terminal node

    • ExtendedTerminalNode

      public ExtendedTerminalNode(ExtendedContext parent)
      Creates a null-token terminal node that has an extended context as a parent. This should only be used when the node is a placeholder for something. It will not be printed since the token is null.
      Parameters:
      parent - The parent node

    • ExtendedTerminalNode

      public ExtendedTerminalNode()
      Creates a null-token and parentless terminal node. This is to be used when the node is a placeholder and it will be added to a parse tree node. Adding it as a child using the node's method will attach it as a parent.
