AccumulatorCache()

def python.AccumulatorCache.AccumulatorCache	(		func = None,
			maxSize = 128,
			verifyResult = AccumulatorDecorator.VERIFY_NOTHING,
			deepCopy = True
	)

Function decorator, implements memoization.

Keyword arguments:
    maxSize: maximum size for the cache associated with the function (default 128)
    verifyResult:   takes two possible values
                    
                    AccumulatorDecorator.VERIFY_NOTHING -   default, the cached function result is returned with no verification
                    AccumulatorDecorator.VERIFY_HASH -      before returning the cached function value, the hash of the
                                                            result is checked to verify if this object was not modified
                                                            between function calls
    deepCopy:   if True (default) a deep copy of the function result will be stored in the cache.

Returns:
    An instance of AccumulatorDecorator.
