Member Functions

Name	Description
traverse	evaluates attributes on the entire AST
traverseWithinFile	evaluates attributes only at nodes which represent the same file as where the evaluation was started

Protected Member Functions

Name	Description
atTraversalEnd [virtual]
atTraversalStart [virtual]	Function called at the start of the traversal, before any node is visited; override if necessary, the default implementation is a no‐op.
destroyInheritedValue [virtual]
evaluateInheritedAttribute [virtual]	pure virtual function which must be implemented to compute the inherited attribute at a node

Description

This class allows computation of 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.

Internal: This class is derived from the SgTreeTraversal class.
