Rick Hillegas updated DERBY-4415:
---------------------------------
Attachment: XmlASTPrinter.java
Attaching a Visitor which prints the parsed, bound, and optimized trees as xml.
This tree printer can be poked into the compiler using the previously attached
database procedure.
> Make it easy to plug custom AST printers into the compiler

> Reporter: Rick Hillegas

> It would be nice to be able to tell the compiler to use user-written
> formatters for pretty-printing Derby's abstract syntax trees. For instance,
> it would be nice to be able to plug in the AST printers attached to
> DERBY-791, including the Eclipse-based tree grapher written by Kay Röpke.
