# To use for a method:
class C(Synchronization):
  def __init__(self):
    Synchronization.__init__(self)
    self.data = 1
  def m(self):
    self.data += 1
    return self.data
  m = synchronized(m)
  def f(self): return 47
  def g(self): return 'spam'

# So m is synchronized, f and g are not.
c = C()

# On the class level:
class D(C):
  def __init__(self):
    C.__init__(self)
  # You must override an un-synchronized method
  # in order to synchronize it (just like Java):
  def f(self): C.f(self)

# Synchronize every (defined) method in the class:
synchronize(D)
d = D()
d.f() # Synchronized
d.g() # Not synchronized
d.m() # Synchronized (in the base class)

class E(C):
  def __init__(self):
    C.__init__(self)
  def m(self): C.m(self)
  def g(self): C.g(self)
  def f(self): C.f(self)
# Only synchronizes m and g. Note that m ends up
# being doubly-wrapped in synchronization, which
# doesn't hurt anything but is inefficient:
synchronize(E, 'm g')
e = E()
e.f()
e.g()
e.m()
