ok question might seem bit basic wonder if should cache variables in functions these: function foobar(target) { var elem = target.children[0].children[1]; if(n == 1) { elem.style.color = "red"; } else { elem.style.color = "blue"; } } vs function foobar(target) { if(n == 1) { target.children[0].children[1].style.color = "red"; } else { target.children[0].children[1].style.color = "blue"; } } there no real performance gain there? assume apart type safety latter better since need less lines. considered best practice in cases these? should still cache object eventhough not needed? so unless if statements included: if(elem.classname == "something") i personaly wouldnt bother caching. at other hand brain in conflict coding style / consistency. assuming have this: function foobar(target) { if(n == 1) { target.children[0].children[1].style.color = "red"; } if e

i'm in middle of fumbling around jpa. i've far created entity representing user data , stateless bean access user data. the data users can work on ( sqlfiddle link ): create table data ( email character varying(128) not null, data character varying(128) not null, lastchange timestamp not null, constraint email_data primary key (email,data) ); the idea save unaltered, current version users empty email key. then, when user alters data , creates auditable version, email field filled users email. way, each user can alter copy of data. merging problem later date , not part of question. now, have entities in place. created stateless bean load/save/find data records using entitymanager. logic load user specific version first, load unaltered version if user has no user specific version still eludes me. consider part of bean: @stateless public class databean { @persistencecontext(unitname = "authpu") private entitymanager em; public list

in every post see on so, involving std::initializer_list , people tend pass std::initializer_list value. according article: http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/ one should pass value, if 1 wants make copy of passed object. copying std::initializer_list not idea, as copying std::initializer_list not copy underlying objects. underlying array not guaranteed exist after lifetime of original initializer list object has ended. so why instance of passed value , not by, const& , guaranteed not make needless copy? it’s passed value because it’s cheap. std::initializer_list , being thin wrapper, implemented pair of pointers, copying (almost) cheap passing reference. in addition, we’re not performing copy, we’re (usually) performing move since in cases argument constructed temporary anyway. however, won’t make difference performance – moving 2 pointers expensive copying them. on other hand, accessing elements of copy may faster sin

i'm try include shared library (.so) in android cross platform dynamic library, put name of "so" dll in project configuration under "addition dependencies" but when compile "linker" doesn't found library. i tested add "path" in "additional library directories" , "shared library path" nothing, same error. works if put entire path name library on "additional dependencies" compiled "so" (opened text reader) reports entire path dll , in runtime call c:.. in android device!?!. someone have same issue ?

i have downloaded , tried eclipse able browse class/interface hierarchy easily. noted "open type hierarchy" feature , works nice when ascendants , descendants of class within same project. however, complication is: classes extend classes other projects. have 2 projects: mysite , myframework. class mysite project called mysite_controller extends myframework_web_controller located in myframework project. when code run, php can see both codebases because autoload configured. however, don't know how eclipse know classes particular prefixes. may have guessed, 2 projects can't joined because myframework used other projects well. so question is: how eclipse correctly show "foreign" parent class mysite_controller in type hierarchy view? view won't show classes files cannot found within current project. p. s. should goal not achievable eclipse, i'd hear names of other php ides can nice , easy. you can achieve adding myframework project

the method jsonconvert.deserializeobjects works when linking set sdk assemblies when build project using link sdk , user assemblies option in linker properties, not work, returns null in fields of deserialized object. you need put [preserve(allmembers = true)] attribute on classes dynamically generated. prevent them being stripped out. you can read more on ios linker here . so lets have list of users want deserialize like. var user = jsonconvert.deserializeobject<user>(json); in user class want place attribute on class. [preserve(allmembers = true)] public class user{ public string email { get; set; } public string firstname { get; set; } public string lastname { get; set; } }

i have viewcontroller uiscrollview, uiimages , uibuttons. in storyboard set size of uiscrollview to: width: 320, height: 570 i want change contentsize of uiscrollview when viewcontroller loaded. i added side in viewdidload: scrlmain.contentsize = cgsize(width: 320,height: 790) and added code in viewdidlayoutsubviews: self.scrlmain.translatesautoresizingmaskintoconstraints = true but uiscrollview still last size = 570. can't use viewdidappear because, when press button, need change color. when has changed color, uiscrollview moves up. what did wrong? all code: override func viewdidload() { super.viewdidload() scrlmain.delegate = self scrlmain.contentsize = cgsizemake(320, 790) } override func viewdidlayoutsubviews() { self.scrlmain.translatesautoresizingmaskintoconstraints = true self.scrlmain.contentsize = cgsize(width: self.scrlmain.frame.width, height: 60.0 + 5 * (self.scrlmain.frame.width / 16.0 * 5.0)); }
