How to work with node.js and mongoDB -

-

i read :

and confused. how should work mongodb node.js? i’m rookie, , question may stupid.

var db = new db.mongoclient(new db.server('localhost', 27017));     db.open(function(err, database) {        //all code here?        database.close();     });

or every time when needing db need call:

mongoclient.connect("mongodb://localhost:27017/mydb", function(err, database) {     //all code here      database.close(); });

what difference betwen open , connect? read in manual open: initialize , second connect. mean? assume both same, in other way, when should use 1 instead other?

i wanna ask it's normal mongoclient needing 4 socket? running 2 mywebserver @ same time, here’s picture: http://i43.tinypic.com/29mlr14.png

edit: wanna mention isn't problem ( rather doubt :d), server works perfect. ask because wanna know if using mongodb driver correctly. now/actually use first option,init mongo dirver @ beginning , inside load put code.

i'd recommend trying mongodb tutorial offer. in same boat, breaks down nicely. in addition, there's this article on github explains basics of db connection.

in short, you're doing right. 

mongoclient.connect("mongodb://localhost:27017/mydb", function(err, database) {     //all code here      var collection = database.collection('users');     var document1 = {'name':'john doe'};     collection.insert(document1, {w:1}, function(err,result){         console.log(err);     });     database.close(); });

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.
