I have a proxy class that wraps an arbitrary file-like object fp and
reads blocks of data from it. Is it safe to assume that fp.read(-1) will
read until EOF? I know that's true for file.read() and StringIO.read(),
but is it a reasonable assumption to make for arbitrary file-like objects?
To put it in more concrete terms, I have a class like this:
class C(object):
# Much simplified version.
def __init__(self, fp):
self.fp = fp
def read(self, size=-1):
return self.fp.read(size)
Should I re-write the read() method like this?
def read(self, size=-1):
if size < 0:
return self.fp.read()
else:
return self.fp.read(size)
