node.js - Node progress bar -

-

i working on example presented in https://github.com/tj/node-progress

i have followed example word word, can't seem functionality of bar.tick() working

var req = http.request({     host: 'download.github.com',     port: 443,     path: '/visionmedia-node-jscoverage-0d4608a.zip' });  req.on('response', function (res) {     //var body = "";     var len = parseint(res.headers['content-length'], 10);     console.log();     var bar = new progressbar(' downloading :bar :percent :etas', {         complete: '=',         incomplete: ' ',         width: 20,         total: len     });      res.on('data', function (chunk) {         //body += chunk;         bar.tick(chunk.length);     });      res.on('end', function () {         console.log('\nfinished loading\n');     });  });  req.end();

the final output looks following

downloading ==================== 100% 0.0s

but instead should show progress data received until complete

ensure you're downloading something, file have been deleted or download instantly completing because there's nothing download.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
