You mean
A) my own tree in the parser ?
no, I do not build. Work ANTLR itself to build AST
B) tree parser?
but how this affect?
and everybody need tree parser ...

Right. This is why in my Reuse() func you can see that I destroy tree
parser, then it is created again later ...

Yes, I am going now spend time to see how work parser->reset() and others
here.
But can you at least give me points, what I should see ?
You set some flags for objects of parser?

This is speed ok. But memory ...
