◆ setASTFactory()
virtual void antlr::TreeParser::setASTFactory |

inlinevirtual |
Specify the AST factory to be used during tree building.
(Compulsory) Setting the factory is compulsory (if you intend to modify the tree in the treeparser). The AST Factory is shared between parser (who builds the initial AST) and treeparser.

The AST Null object; the parsing cursor is set to this when it is found to be null.
This way, we can test the token type of a node without having to have tests for 0 everywhere.
