RewriteRuleNodeStream (ANTLR 3 Runtime 3.5.3 API)

java.lang.Object
- org.antlr.runtime.tree.RewriteRuleElementStream
- - org.antlr.runtime.tree.RewriteRuleNodeStream

```
public class RewriteRuleNodeStream
extends RewriteRuleElementStream
```
Queues up nodes matched on left side of -> in a tree parser. This is the analog of RewriteRuleTokenStream for normal parsers.

    Ensure stream emits trees; tokens must be converted to AST nodes. AST nodes can be passed through unmolested.

```
protected Object dup(Object el)
```
    Description copied from class: RewriteRuleElementStream
    
    When constructing trees, sometimes we need to dup a token or AST subtree. Dup'ing a token means just creating another AST node around it. For trees, you must call the adaptor.dupTree() unless the element is for a tree root; then it must be a node dup.
