Sorry, "re-iterables". A file re-iterable is:
class FileReIterable(object):
def __init__(self, file):
if isinstance(file, basestring):
self.file = open(file, 'rU')
else:
self.file = file
def __iter__(self):
self.file.seek(0)
return iter(self.file)
This works if-and-only-if it is only in use once at a time.
If you have multiple simultaneous accesses, you need to do
something like:
class FileReIterable2(object):
def __init__(self, file):
if isinstance(file, basestring):
self.file = open(file, 'rU')
else:
self.file = file
def __iter__(self):
self.file.seek(0)
for line in self.file:
nextpos = self.file.tell()
yield line
self.file.seek(nextpos)
