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.
