Member Documentation

walk_expression(expr)

Walk an expression, calling registered callbacks.

This is the standard interface for running the visitor. It defaults to using an efficient recursive implementation of the visitor, falling back on walk_expression_nonrecursive() if the recursion stack gets too deep.

walk_expression_nonrecursive(expr)

Nonrecursively walk an expression, calling registered callbacks.

This routine is safer than the recursive walkers for deep (or unbalanced) trees. It is, however, slightly slower than the recursive implementations.
