so here worthy downvote question. i understand java pass value , means , how works. not can explain pass value is. more curious why java not include pass reference? imagine useful? helpful know cement reasoning in head.... i hate 'it because is' scenarios surely equivalent of 'because said so'. have answer why java includes pass value? o'reilly's java in nutshell david flanagan puts best: "java manipulates objects 'by reference,' passes object references methods 'by value.'" design decision java. when pass objects around, still manipulating same underlying object reference same memory location. i'm not sure specific scenario thinking can't existing java mechanisms.

in linear layout have 2 listview's vertically oriented. want add "second slide" 2 more listview's simmilar before. when open app, first 2 listview vertically oriented shown, , when scroll right 2 listview shown. and tried horizontal scroll, had 2 linear layout in horizontal scroll view brackets. in first linear layout first 2 listview's , in second linear layout 2 ... and got in console: horizontalscrollview can host 1 direct child... so, if i'm right, can't have 2 linear layouts in horizontalscrollview. have idea how it? i'm new in android, don't have idea how it... thank you, matija :) so, if i'm right, can't have 2 linear layouts in horizontalscrollview that's correct, @ least not 2 direct children of scrollview error message tells you. you could, however, wrap 2 linearlayout s in linearlayout (sounds horizontal orientation though i'm having trouble picturing doing). if explain little better tryin

i'm new here, can't comment/follow-up yet on question partially provided answer i'm trying achieve. on question here [ moving background image in loop left right fantastic , detailed answer jack pattishall jr lets me set page background scroll either vertically or horizontally. is there way combine directional code, page background scrolls diagonally (i.e. bottom left top right)? i've been "mutilating" jack's code days now, can't figure out how make background scroll in 2 directions simultaneously. :-( starting example mentioned above , here changes: html, body { height: 100%; width: 100%;} body { background-image: url('http://coloradoellie.files.wordpress.com/2013/10/25280-ginger-kitten-leaping-with-arms-outstretched-white-background.jpg?w=300&h=222'); background-repeat: repeat-x repeat-y; // line removed entirely } $(function(){ var x = 0; var y = 0; setinterval(function(){ x+=1;

i'm searching code example of lightbox demo famo.us. unfortunately, interesting part of app in codepen uglified in pens version of famous.lib.js. it's not whole gallery thing i'm interested in, "just" scollable view multiple elements in 1 row, depending on size , screen size. has experiences in developing view/layout this? thanks in advance i have been doing work scrollview , gridlayout. can calculate grid dimensions based on contextsize , target/min cell size. here example started. adding gridlayout sole view in scrollview. know may work against scrollviews efficient rendering in scrollview rendering entire grid, doing examples sake. use modifier around gridlayout ensure size of view calculated , scrollview scrolls right amount. anyway, here did.. var engine = require('famous/core/engine'); var surface = require('famous/core/surface'); var rendernode = require('famous/core/rendernode'); var mod

i have bunch of images foldered this: /first/345.jpg /second/12.jpg /third/394.jpg /fourth/234.jpg /fifth/5.jpg i'm trying go through folders , load image contained. there 1 image in each folder. how can tell javascript choose image, regardless of name? look @ code: for (var i=0; i<dirlist.length; i++) { // dirlist array containing folder names something.load.image("c:/.../"+ dirlist[i] +"/"+ anydigit + ".png"); } how can replace "anydigit" make work? regular expressions? thank you! just tested this. following list png in directory 1/ , 2/ var dirs = ['1/', '2/']; $.each(dirs, function(i, dir) { $.ajax({ url: dir, success: function(data) { $(data).find("a:contains(.png)").each(function() { var href = $(this).attr('href'); $('<p></p>').html(href).appendto($('div')); }); }}); });

(post edited again, new comments follow line) i'm changing title of posting since misleading - trying fix symptom. i unable figure out why code breaking $digest() iterations error. plunk of code worked fine. totally stuck, decided make code little more angular-like. 1 anti-pattern had implemented hide model behind controller adding getters/setters controller. tore out , instead put model $scope since had read proper angular. to surprise, $digest() iterations error went away. not know why , not have intestinal fortitude put old code , figure out. surmise involving controller in get/put of data added dependency under hood. not understand it. edit #2 ends here. (post edited, see edit below) i working through first error: 10 $digest() iterations reached. aborting! error today. i solved way: <div ng-init="lineitems = ctrl.getlineitems()"> <tr ng-repeat="r in lineitems"> <td>{{r.text}}</td> <td>

i want dynamically change current cgcontextref according different user actions? possible or modification possible within drawrect: of view instance? happens when call uigraphicsgetcurrentcontext() outside drawrect: , there limitations in doing so, recommended? possible implications need consider? according docs graphics context set before function called. means if function not called won't set , if don't make system call again (never reason) won't there either. use 1 of these functions force view drawrect: setneedsdisplay: setneedsdisplayinrect: it doesn't mean can stuff inside drawrect however. context sort of globally available @ moment , can call clean separate functions or classes drawing things. passing reference functions clean way it.

is possible save file users local downloads folder without prompting them save dialog? i have application user right mouse clicks choose option save specific file. i have used ihttphandler interface not sure how call handler in code system start saving downloads file without user having navigate different page one way out host required file on public url , navigate url in new tab/window silverlight app.. htmlpage.window.navigate(new uri("<your file's url>"), "_blank"); this should cause browser open link in new tab , in turn download automatically (occasionally depending on user settings)..

i'm curious how rails achieves this. notice can access flash variable globally in app, isn't prefixed @ or $ . i can see there's method accessing flash , there's initializer set @flash , how can call flash local variable? session further apneadiving 's answer, flash part of middleware stack ( actiondispatch::flash ). it's non-persistent session cookie: -- from the docs : the flash special part of session cleared each request. means values stored there available in next request, useful passing error messages etc. much in same way params works (on per request basis), flash variable populated data previous request. -- middleware if take apneadiving 's comment, you'll see flash created through middleware stack - meaning local nature of variable set particular request (much same params ). why can access / set flash message in controller - because it's defined higher "middleware stack" - provides
