Hi i made a wrapper class for handling file and dir operations and i wonder,
whats the performance penalty for making such wrapper classes? here it is:
##################################
import os
class File(object):
#access modes
F_OK = os.F_OK,
W_OK = os.W_OK,
R_OK = os.R_OK,
X_OK = os.X_OK
def __init__(s,pathToFile):
s.path = pathToFile
s.name = os.path.basename(s.path)
s.dirName = os.path.dirname(s.path)
#s.size = path.getsize(s.path)
def size(s):
return os.path.getsize(s.path)
def open(s,mode='r'):
return open(s.path,mode)
def openw(s):
return open(s.path,'w')
def access(s,mode):
return os.access(s.path,mode)
def abspath(s):
return os.path.abspath(s.path)
def getatime(s):
return os.path.getatime(s.path)
def getctime(s):
return os.path.getctime(s.path)
def isabs(s):
return os.path.isabs(s.path)
def isfile(s):
return os.path.isfile(s.path)
def isdir(s):
return os.path.isdir(s.path)
def ext(s):
return os.path.splitext(s.path)[1]
def stat(s):
return os.stat(s.path)
def access(s,mode):
return os.access(s.path,mode)
def chdir(path) : os.chdir(path)
def cwd() : return os.getcwd()
def chmod(path,mode): return os.chmod(path,mode)
def chown(path,uid,gid): os.chown(path,uid,gid)
def ln(src,dest): os.symlink(src,dest)
def ls(path): return os.listdir(path)
def mkdir(path,rec=False,mode = 0777) :
if not rec:
os.mkdir(path,mode)
else:
os.makedirs(path,mode)
def rm(path): os.remove(path)
def rename(old,new): os.rename(old,new)
def rmdir(path): os.rmdir(path)
def xremove(path) :
'just unix'
os.system('rm -rf %s' % path)
def utime(path,times=None):
'set times of a file\
times = tuple like (atime,ctime) '
os.utime(path,times)
if __name__ == '__main__':
f = File('/tmp')
print f.isfile()
print f.isdir()
print f.size()
print ls('/tmp')
