Public Member Functions

virtual void at_enum (enumNode *the_enum, Order ord)
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.

Detailed Description

visits each enum value

WARNING: This is only temporary. The evaluation of the initializers must be more general and powerful. This functionality should be integrated into the semantic checker.
