- /** <summary>
- * A TreeAdaptor proxy that fires debugging events to a DebugEventListener
- * delegate and uses the TreeAdaptor delegate to do the actual work. All
- * AST events are triggered by this adaptor; no code gen changes are needed
- * in generated rules. Debugging events are triggered *after* invoking
- * tree adaptor routines.
- * </summary>
- *
- * <remarks>
- * Trees created with actions in rewrite actions like "-&gt; ^(ADD {foo} {bar})"
- * cannot be tracked as they might not use the adaptor to create foo, bar.
- * The debug listener has to deal with tree node IDs for which it did
- * not see a createNode event. A single &lt;unknown&gt; node is sufficient even
- * if it represents a whole tree.
