    • accept

      public Node accept(NodeVisitor<? extends LexicalContext> visitor)
      Assist in IR navigation.
      Specified by:
      accept in class Node
      Parameters:
      visitor - IR navigating visitor.
      Returns:
      node the node or its replacement after visitation, null if no further visitations are required

    • accept

      public <R> R accept(TranslatorNodeVisitor<? extends LexicalContext, R> visitor)
      Description copied from class: Node
      Provides a means to navigate the IR.

      accept in class Node
      Parameters:
      visitor - Node visitor.
      Returns:
      node the node or its replacement after visitation, null if no further visitations are required

    • toString

      public void toString(StringBuilder sb, boolean printType)
      Description copied from class: Node
      Print logic that decides whether to show the optimistic type or not - for example it should not be printed after just parse, when it hasn't been computed, or has been set to a trivially provable value
      Specified by:
      toString in class Node
      Parameters:
      sb - string builder
      printType - print type?
