Public Member Functions

 vcgWalker (ostream &ostr, const string &comment, string excludefilename)
virtual ~vcgWalker (void)
Accessors
Methods to get and set fields in the class.

Order order () const
 Return the order in which Nodes of an AST should be visited.

Depth depth () const
 Return which Nodes of an AST should be visited.

"at_" methods
These methods define the functions that should be performed when different classes of Nodes are encountered in the AST. The most specific "at_" method that matches a given Node's class will be called.
