[antlr-interest] Bug ? In C++, the parameters passed to a rule become ASTRefCount<AST>

[Anthony Brenelière]

// Here is the root rule, ciaoTreeDocument :

 

ciaoTreeDocument

      :     ( statementA )*

;

 

// A pointer is created, named '_curstat'.

// This pointer is passed to the rule 'statProperties'

// Everything is OK when the rule is called, and _curstat is OK, with a
type 'CObject *'

 

statementA

      {     

            CObject * _curstat = world->addObject();

            _curstat->aP(CATEGORY, "Statement"); 

      }

      :     #(R_STA ( statProperties[ _curstat ])* statement) 

;

 

// In the statProperties rule, _curstat has changed : the value of the
pointer has changed, // and the type of _curstat has also changed :

 

// _curstat IS NOW 'antlr::ASTRefCount<antlr::AST>' instead of 'CObject
*' !!!!!!!!!!!

 

statProperties

      [ CObject * _curstat ]

      :     statStateA[ _curstat ]

      |     statId[ _curstat ]

;

 

So, my question is :

 

Any idea to pass a pointer from a rule to another rule in the Treewalker
in

C++ ?

 

Cordially,

Anthony
