[ZODB-Dev] how can I get the size of ZODB.Blob object ?

[KLEIN Stéphane]

Hi,

I've take cognizance of ZODB.Blob. I think it's great tools.

Know, I've one question : how can I get the size (in octet) of Blob 
object ?

>>> f = myblob.open("r")
>>> size = len(f.read())
>>> print size

This code isn't efficient. What is the good method ?

Thanks for your help,
Stephane
