Detailed Description

template<class InheritedAttributeType>
class AstTopDownProcessing< InheritedAttributeType >

Attribute Evaluator for inherited attributes.

This class allows to compute inherited attributes on the AST. It requires an inherited attribute type as a template parameter and the implementation of the function evaluateInheritedAttribute. This function is invoked in pre-order while the AST is traversed. It can be used for passing context information down the AST.

For internal use only.

This class is derived from the SgTreeTraversal class.

Public Member Functions
void	traverse (SgNode *node, InheritedAttributeType inheritedValue)
	evaluates attributes on the entire AST
void	traverseWithinFile (SgNode *node, InheritedAttributeType inheritedValue)

	pure virtual function which must be implemented to compute the inherited attribute at a node
virtual void	atTraversalStart ()
	Function called at the start of the traversal, before any node is visited; override if necessary, the default implementation is a no-op.
