Detailed Description
Queues up nodes matched on left side of -> in a tree parser. This is the analog of RewriteRuleTokenStream for normal parsers.Definition at line 35 of file RewriteRuleNodeStream.java.

| Object org.antlr.runtime.tree.RewriteRuleNodeStream.toTree | ( | Object | el | ) | [protected] |
Ensure stream emits trees; tokens must be converted to AST nodes. AST nodes can be passed through unmolested.
Reimplemented from org.antlr.runtime.tree.RewriteRuleElementStream.
Definition at line 61 of file RewriteRuleNodeStream.java.
| Object org.antlr.runtime.tree.RewriteRuleNodeStream.dup | ( | Object | el | ) | [protected, virtual] |
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.
Implements org.antlr.runtime.tree.RewriteRuleElementStream.
