model view controller - How does business logic class calls methods inside a managed bean? -

i have business logic code renders facesmessages on facelet based on output, made method in facelet managed bean method: public void renderfacesmessages(string summary, string detail) { facesmessage message = new facesmessage(summary, detail); facescontext.getcurrentinstance().addmessage(null, message); } and business logic class pass arguments method according message that's needed, question right approach business logic call method on managed bean? it layering concept... i presume have managedbean has method delegate business logic seperate business class/module. if case,i tell ,never have faces methods on business side... instead have business results wrapped in class , return managed bean.this result class encompass results,meta information result like,errors,exceptions.so managed bean can use renderfacesmessage method even if had not followed above presumption:my suggestion never have jsf faces logic inside business components.it bad idea.

python - Multiple operations in a List Comprehension -

say this: vlist=[1236745404] flist=[ "<td>{}</td>".format ] [ f(x) f, x in zip(flist, vlist) ] but want convert integer time string feeding multiple process stream. pseudocode: flist=[ "<td>{}</td>".format(time.strftime("%a %h&#58;%m %d %b %y", time.localtime())) ] [ f(x) f, x in zip(flist, vlist) ] and want see is: ['<td>tue 22&#58;23 10 mar 09</td>'] is list comprehension variable input limited 1 operation, or can output passed downstream? your 2 cases quite different; in first have callable ( str.format ) in second built complete string. you'd need create callable second option too; in case lambda work: flist=[lambda t: "<td>{}</td>".format(time.strftime("%a %h&#58;%m %d %b %y", time.localtime(t)))] this list 1 callable, lambda accepts 1 argument t , , returns result of full expression t passed time.localtime() formatted using

python - Leibniz determinant formula complexity -

i wrote code calculates determinant of given nxn matrix using leibniz formula determinants . i trying figure out it's complexity in o-notation. think should like: o(n!) * o(n^2) + o(n) = o(n!*n^2) or o((n+2)!) reasoning: think o(n!) complexity of permutations. , o(n) complexity of perm_parity, , o(n^2) multiplication of n items each iteration. this code: def determinant_leibnitz(self): assert self.dim()[0] == self.dim()[1] # o(1) dim = self.dim()[0] # o(1) det,mul = 0,1 # o(1) perm in permutations([num num in range(dim)]): in range(dim): mul *= self[i,perm[i]] # o(1) det += perm_parity(perm)*mul # o(n) ? mul = 1 # o(1) return det the following functions wrote used in calculation: perm_parity: given permutation of digits 0..n in order list, returns parity (or sign): +1 parity; -1 odd. i think perm_parity should run @ o(n^2) (is correct?). def perm_parity(lst): parity = 1 lst = lst[:] in rang
