singleton

pyserver also has a singleton container. When creating singleton class, it can be simply done by adding an annotation:

from pyserver.util import *
... 

@Singleton
class TempSingletonClass(object):
    def __init__(self):
       self.text = 'Hello World'
   
    def touch(self):
       print self.text

...

TempSingletonClass.instance().touch() # 'Hello World'

* Note that the Singleton class must not have any mandatory argument for the contructor!
