-Ph0dZddlmZGddZdS)a Implements a buffer with insertion points. When you know you need to "get back" to a place and write more later, simply call insertion_point() at that spot and get a new StringIOTree object that is "left behind". EXAMPLE: >>> a = StringIOTree() >>> _= a.write('first\n') >>> b = a.insertion_point() >>> _= a.write('third\n') >>> _= b.write('second\n') >>> a.getvalue().split() ['first', 'second', 'third'] >>> c = b.insertion_point() >>> d = c.insertion_point() >>> _= d.write('alpha\n') >>> _= b.write('gamma\n') >>> _= c.write('beta\n') >>> b.getvalue().split() ['second', 'alpha', 'beta', 'gamma'] >>> try: from cStringIO import StringIO ... except ImportError: from io import StringIO >>> i = StringIOTree() >>> d.insert(i) >>> _= i.write('inserted\n') >>> out = StringIO() >>> a.copyto(out) >>> out.getvalue().split() ['first', 'second', 'alpha', 'inserted', 'beta', 'gamma', 'third'] )StringIOcPeZdZdZd dZdZdZdZdZdZ d Z d Z d Z d Z dS) StringIOTreez See module docs.
