Detailed Description
Queues up nodes matched on left side of -> in a tree parser. This is the analog of RewriteRuleTokenStream for normal parsers.

| el | |||
| ) |
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.
Reimplemented from rve_interface_gen.antlr3.tree.RewriteRuleElementStream.
| def rve_interface_gen.antlr3.tree.RewriteRuleNodeStream.toTree | ( | self, | |
| el | |||
| ) |
Ensure stream emits trees; tokens must be converted to AST nodes. AST nodes can be passed through unmolested.
