Hi i made a wrapper class for handling file and dir operations and i wonder,
�whats�the�performance�penalty�for�making�such�wrapper�classes?�is it ok to
make a lot of these wrappers? 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')
