i know since java 8, if hashmap has enough hash collisions, , keys implement comparable , use balanced tree instead of linked list bin . can see, comparable interface does not require compareto() "consistent equals() " (though recommended). did miss something? seems new implementation allows hashmap violate requirements of map interface if keys happen have compliant, non-recommended comparable implementation. the following junit test exposes behaviour on openjdk 8u72: import static org.junit.assert.*; import java.util.hashset; import java.util.set; import org.junit.test; class foo implements comparable<foo> // comment out fix test case { private final int bar; private final int baz; foo(int bar, int baz) { this.bar = bar; this.baz = baz; } public boolean equals(object obj) { // note ignores 'baz' return obj instanceof foo && bar == ((foo) obj).bar; } public int h

i have c,linux background less knowledge web application. came across strange requirement, , finding difficult providing solution. requirement in short: one code/multiple platforms[ mobile desktop] what know: 1) ui front. webview provided across mobile, desktop applications. [ atlease know for: ios, mac, in windows/linux/mac qt ]. conclusion: can have html5 code, can utilized across desktop/mobile platform. problem: how native access html/javascript. go phonegap supports mobile, not desktop [ correct me if wrong]. , if go qt, not support android/ios [ correct me if wrong]. 2) writing middle layer in c++: ios/windows/mac/android supports c++. question: in ios/android know how bring webview using xcode. how can webview in windows , mac. in short, have open source framework supports mac/windows/ios/android is possible write our own native function invoke mechanism javascript c++ code, common. kindly suggest. answer : you can lau

var funcs = []; (var = 0; < 3; i++) { // let's create 3 functions funcs[i] = function() { // , store them in funcs console.log("my value: " + i); // each should log value. }; } (var j = 0; j < 3; j++) { funcs[j](); // , let's run each 1 see } it outputs this: my value: 3 value: 3 value: 3 whereas i'd output: my value: 0 value: 1 value: 2 what's solution basic problem? well, problem variable i , within each of anonymous functions, bound same variable outside of function. what want bind variable within each function separate, unchanging value outside of function: var funcs = []; function createfunc(i) { return function() { console.log("my value: " + i); }; } (var = 0; < 3; i++) { funcs[i] = createfunc(i); } (var j = 0; j < 3; j++) { funcs[j](); // , let's run each 1 see }

i've been looking @ quite few of mvc javascript frameworks lately , quite overall feel of spine.js fact using coffeescript. said, primary concern @ stage need able drop mvc framework iteratively large existing application. of documentation have seen on spine.js focuses on creating new applications. does have suggestions on best way go doing this; if there tutorial somewhere great too, google not friend on one. or bad idea , should go elsewhere when dealing legacy? while angular didn't click me in same way; did seem pretty straight forward on how use iteratively legacy application. i think it's rather bad idea "iteratively". i'm working freelancer company decided complete ui rework splited on few releases. in first stage planned drop existing js , use spine js mvc , require js amd. far - process "iteratively". project/app quite complex , took on half year (i'm involved since 2,5 months). it big mistake leave existing js , &

i found answer question via simple google search, although, there slight problem ran into. so far, have image on html page id of newavatar. attempting find image via id, , save it's source variable, xml document used later on. when save source variable, or alert checking purposes, displaying full source, unusual. example, running site on wamp server, variable saving as: http://localhost/uploads/newuploadedimage.jpg when in reality, source should plain , simple, uploads/newuploadedimage.jpg the image tag is <img src="uploads/newuploadedimage.jpg" width="60px" height="60px;" id="newavatar"/> the way checking source is alert(document.getelementbyid('newavatar').src); any idea how rid of first lot of junk? all appreciated! by using @davidthomas comment before, managed working. changed alert to: alert(document.getelementbyid('newavatar').getattribute('src'));

when drop unique column (just unique not primary key) constraint, toad prompts me whether if want keep index. to me logical thing remove index why offer keep ? saving time if make same column unique @ later point in time ? (which kind of confuses me since old index may cause conflicts). as of 10g, oracle introduced "keep index" option on alter table...drop constraint . i've read, should other way around...in should drop index unless specify "keep index". assuming removed index via gui menus. with in mind, toad gui designed prompt that. wonder if ran alter table...drop constraint if still prompt you. going bet "not."

i´m trying hide/show own kml files (polygons) depending on zoom levels in openlayers - when reached zoom level 1 layer should hide , show. far found solution ( how load layers depending on zoom level? ), doesn´t seem working in case. i´m relatively new javascript , don´t know if i´m using right, made changes example: map.events.register("zoomend", map, zoomchanged); //inserted in function init() function zoomchanged() { if (map.getzoom() == 18) { kml1.setvisibility (true); kml2.setvisibility (false); } else if (map.getzoom() == 19) { kml1.setvisibility (false); kml2.setvisibility (true); } } i tried solution hide kml1, in case layer isn´t drawn. layerswitcher works - layer unselectable in defined zoom levels, nothing visible when zoomed out (when layer selectable): var kml1 = new openlayers.layer.vector("prehled", {minscale: 1000,}, //1:10
