Setup

To use the cacheing service add the following to your py file.

 try:
   import StorageServer
 except:
   import storageserverdummy as StorageServer
 cache = StorageServer.StorageServer()
 cache.table_name = "PluginName" # Name of your plugni.

You can now access the caching service through the "cache" variable.

cacheFunction(self, funct = False, *args)

Caching function results for one hour.

The function being cached must return a tupple ( function_return, status), a status of 200 means the result is ok and should be cached. Any other value and the function result will be returned, but not cached.

 def pi_count(self):
     def arccot(x, unity):
         sum = xpower = unity // x
         n = 3
         sign = -1
         while 1:
               xpower = xpower // (x*x)
               term = xpower // n
               if not term:
                       break
               sum += sign * term
               sign = -sign
               n += 2
         return sum
  
     digits = 40
     unity = 10**(digits + 10)
     pi = 4 * (4*arccot(5, unity) - arccot(239, unity))
     return (pi // 10**10, 200)
 
 result = cache.cacheFunction(pi_count) # This will call the pi_count function, save the result in the cache, and return the result.
 time.sleep(300)
 result = cache.cacheFunction(pi_count) # This will return the cached result
 time.sleep(3600)
 result = cache.cacheFunction(pi_count) # This will again call pi_count since the result is now considered stale.
