suppose interface like: public interface fooer { void foo(); boolean isfooed(); } this part of java library i'm writing. users of library supposed implement interface , pass objects library. i want provide way users test their implementation hold invariants my library code assumes. following above example: fooer f = getusersfooer(); f.foo(); // f.isfooed() must return true is possible, , if so, feasible or acceptable provide such tests part of library? (i don't know whether these considered unit tests or integration tests ... test modifications made single method using getter methods or primitive non-mutating methods) sure, can write classes like public class testfooer { public static boolean test(fooer f) { // ... } } but there "standard way", using usual testing frameworks (junit, ...) ?

i need lexical parser parse c source codes , have using java language. researched , saw antlr , javacc. of these parsers better use , why? or have other parser recommend? answers appreciated. thanks. a lexer breaks input stream tokens. don't count incomplete purpose of computing simple metrics. if want differentiate "functions" "variables" you'll need kind of parser check sequences of tokens determine represent (e.g., "a variable declaration, use, or function declaration"). can build ad hoc parser may satisfy counting needs @ price of making occasional mistakes, or can real parser , right. (parsing c variable declaration lot harder looks @ first glance; pretty arcane syntax). if homework, or real problem , don't care if answer wrong, lexer generator , ad hoc parsing code enough. if want accurately, you'll need preprocessor , parser, , you'd better (implicitly including lexer).

i'm wondering if can explain in simple enough terms intra-record integrity means when working databases? definition have "enforcing constraints on contents of fields linked data validation" hoping elaborate further?.. here 1 explanation depends heavily on word "intra-record". let's start example, lets have health record patient, has fields such as id gender age date_of_birth last_menstrual_date now if value of gender male , last_menstrual_date null or blank. similarly if have populated both fields age , date_of_birth, , lets have date_of_birth = january 1 1976 , age = 30, incorrect since if person born on january 1 1976 age should 40 or, if age in fact 30 date_of_birth should january 1 1986 . note: bad design include both age , date_of_birth columns in same table, above show case of data integrity so way fields within record i.e. intra-record valid , not violate data integrity. this 1 explanation of intra-record data integrity ...

i have class class myclass{ private $id; private $name; public function __construct ($id, $name){ $this->name = $name; } } $ob1 = new myclass(1, 'earth'); $ob2 = new myclass(2, 'sky'); $ob3 = new myclass(3, 'ocean'); i want objects $ob1, $ob2 , $ob3 have different attribute $id. example when make : $ob4 = new myclass(3, 'wood'); the code denies me create object thanks you need keep track of ids in static class property: class myclass { static private $ids = []; public function __construct($id) { if (in_array($id, self::$ids)) { throw new exception("object id $id constructed"); } self::$ids[] = $id; } } having said this, question usefulness of this. sounds recipe problems. should keep track of unique data part of business logic , database interaction, not enforced on language level.

i implementing random sampling / montecarlo heuristic travelling salesman problem. want perform maximum c iterations, while being able stop search when want ctrl + c or sending sigint process. i know has been asked before (related: quitting node.js gracefully ) given solution not working me. process doesn't exit when give ctrl + c , if kill it, finalizing code not executed. my code: var tsp = require("./tsp.js"); var data = tsp.load("./input/it16862.tsp"); var starting_point = data.splice(10927, 1)[0]; var c = 0; var cost = number.positive_infinity; var new_cost, solution, candidate_solution; var interrupt = false; var c = 0, interrupt = false; process.on('sigint', function() { interrupt = true; }); while(c < 1000000000) { if (interrupt) { break; } candidate_solution = shuffle(data); new_cost = tsp.cost(candidate_solution, starting_point); if (new_cost < cost) { cost = new_cost; solut...

session variable becomes null when called public partial class outside methods. if called inside methods value available. code initialize sql connection string not work intended. public partial class doctor_default : system.web.ui.page { sqlconnection con = new sqlconnection(session["connectionstring"].tostring()); protected void page_load(object sender, eventargs e) { } } maybe work you: string constring; sqlconnection con; protected void page_load(object sender, eventargs e) { constring = session["connectionstring"].tostring(); // check here constring == null, if necessary. con = new sqlconnection(constring); }

what null pointer exceptions ( java.lang.nullpointerexception ) , causes them? what methods/tools can used determine cause stop exception causing program terminate prematurely? when declare reference variable (i.e. object) creating pointer object. consider following code declare variable of primitive type int : int x; x = 10; in example variable x int , java initialize 0 you. when assign 10 in second line value 10 written memory location pointed x. but, when try declare reference type different happens. take following code: integer num; num = new integer(10); the first line declares variable named num , but, not contain primitive value. instead contains pointer (because type integer reference type). since did not yet point java sets null, meaning "i pointing @ nothing". in second line, new keyword used instantiate (or create) object of type integer , pointer variable num assigned object. can reference object using dereferencing operator .

i have simple problem i'm hoping can shed light on. have child theme custom page template , i'm trying check weather or not template in use. under normal circumstances, have used is_page_template function, doesn't seem working child themes. i've tried following if(is_page_template('template-custom-fullwidth.php')){ //do something.. } as if(is_page_template(dirname(get_bloginfo('stylesheet_url')).'/template-custom-fullwidth.php'){ //do something.. } neiter works , hoping there more elegant solution using $_server check urls. can't imagine there not being function seeing seems common task. believe problem difference between template , stylesheet directories. possible use wordpress check page templates located in child theme? thanks in advance! reference wp codex page: http://codex.wordpress.org/function_reference/get_stylesheet_directory_uri use get_stylesheet_directory_uri instead. should work: is_pa...

situation suppose have orders , clients entities in application. in 1 aggregate, order entity considered root want make use of client entity simple things. in client root entity , order entity touched ever lightly. an example: let's in order aggregate use client read details name, address, build order history , not make client client specific business logic. (like persistence, passwords resets , flips..). on other hand, in client aggregate use order entity report on client's buying habbits, order totals, order counting, without requiring advanced order functionality order processing, updating, status changes, etc. possible solution i believe better solution create entities each aggregate specific aggregate context, because making them full featured (general purpose) , ready situation , usage seems overkill , potentially become maintenance nightmare. (and potentially memory intensive) question what ddd recommended way of handling situation? take on matter? ...

i new code contracts may have done stupid here :) i getting error detected expression statement evaluated potential side-effect in contracts of method '##'. (did mean put expression requires, ensures, or invariant call?) i have following contracts contract.requires<argumentnullexception>(obj != null); contract.requires<argumentnullexception>(obj.id != null); it failing on second contract obj.id != null ( id guid ) now possible id null isn't allowed in method. code contracts raises above compile error. method self doesn't return needs no ensures either. i have removed contract can compile , placed standard if check. causing this? you need mark id property [pure] that tell code contracts analyser has no side-effects. code contracts don't calling methods have side-effects; code behave differently depending on whether had code contract checking enabled or not, bad thing. example: public guid id { [pure] ...
