[antlr-interest] Re: A way to find all subtrees of a particular type?

[lgcraymer]

There is a quick fix.  Redefine "equals" in your base AST class so 
that some text string--say ""--matches anything.  That way, "equals" 
has the default behavior in all but the one special case and you get 
the match behavior that you want by using the special string when 
building an AST for the findAllPartial().
