[antlr-interest] Controlling a TreeParser

[Kevin Ruland]

Hi all.

Suppose I've written an antlr3 grammar which produces an AST and I've 
written the corresponding tree parser.  Are there any hooks available in 
the generated tree parser to support development of a debugger for my 
language?  I need to control execution of the tree grammar at a very 
fine level of detail including stepped execution, breakpoints, and even 
serialization of execution state and corresponding deserialization and 
resuming execution.

Any ideas or suggestions?

Thanks much.
