Recursively apply the given block to each node that gets visited with the given key which nodes get traverses for a given key can be set on a class via the: traverse :name, :child_1, :child2 macro. If no children are defined for a given traversal path name the block is invoked only with self.ode that gets visited with the given key which nodes get traverses for a given key can be set on a class via the: traverse :name, :child_1, :child2 macro.
