    • close

      public static void close(Node node)
      Make sure that all variables reachable from node are marked not available, indicating that they are no longer in scope. Note that only defining occurrences of variables are to be considered here, as a scope that merely references a variable may be closed while the containing defining scope is still open.
    • checkScope

      public static void checkScope(ExpressionInternal expr)
      Throw an exception if any ExpressionInternal reachable from expr contains a Variable that is out of scope. Note that this is only useful for Expressions.
    • checkTree

      public static void checkTree(Node node, PrintStream pw)
      Check that node is really a tree, that is, when we traverse it with the visitor, we never encounter the same node twice.
    • displayAttributes

      private static void displayAttributes(Node node, CodegenPrinter pr)
    • getNodeIdString

      public static String getNodeIdString(Node obj)
    • display

      public static void display(Node node, PrintStream pw)
      Display a tree for the node.
