NodeVisitor function ( Node arg0 , Node arg1 ) { return enter ( arg1 ) ; }
begin normal traversal of a subtree rooted at n . this gives the visitor the option of changing internal state or returning a new visitor which will be used to visit the children of n . the default implementation of this method is to call #enter node enter n , as most subclasses do not need to know the parent of the node n . concode_field_sep Lang lang concode_field_sep N visitEdgeNoOverride concode_elem_sep Node leave concode_elem_sep Node leave concode_elem_sep void finish concode_elem_sep void finish concode_elem_sep String toString concode_elem_sep Node override concode_elem_sep Node override concode_elem_sep N visitEdge concode_elem_sep NodeVisitor copy concode_elem_sep Lang lang concode_elem_sep NodeVisitor begin
