javascript - Expected null({ }) to equal Object({ }) -

-

i have been trying run angularjs own unit tests of $resource. difference i'm running jasmine v2.0 , karma v0.13.
did work of converting custom actions older jasmine newer, tests pass. all...

i have stumbled 1 type of tests. believe have $httpbackend. whilst testing this line see fails:

expected null({ }) equal object({ }).

actual test code, problem latest expectation:

      // ---        callback = jasmine.createspy();        // ---          it("should create resource", function() {          $httpbackend.expect('post', '/creditcard', '{"name":"misko"}').respond({id: 123, name: 'misko'});            var cc = creditcard.save({name: 'misko'}, callback);          expect(cc).toequaldata({name: 'misko'});          expect(callback).not.tohavebeencalled();            $httpbackend.flush();          expect(cc).toequaldata({id: 123, name: 'misko'});          expect(callback).tohavebeencalledonce();          expect(callback.calls.mostrecent().args[0]).toequal(cc);          expect(callback.calls.mostrecent().args[1]()).toequal({});        });

update

found it.
turns out, angular uses function bellow create empty object. newest versions of jasmine fails on calling objects instantiated null , {} equals.

/**  * creates new object without prototype. object useful lookup without having  * guard against prototypically inherited properties via hasownproperty.  *  * related micro-benchmarks:  * - http://jsperf.com/object-create2  * - http://jsperf.com/proto-map-lookup/2  * - http://jsperf.com/for-in-vs-object-keys2  *  * @returns {object}  */ function createmap() {   return object.create(null); }

after looking @ angularjs source, see objects created using object.create(null), in snippet below.

/**  * creates new object without prototype. object useful lookup without having  * guard against prototypically inherited properties via hasownproperty.  *  * related micro-benchmarks:  * - http://jsperf.com/object-create2  * - http://jsperf.com/proto-map-lookup/2  * - http://jsperf.com/for-in-vs-object-keys2  *  * @returns {object}  */ function createmap() {   return object.create(null); }

looks jasmine 2.0 added comparison prototype type well, expectation fails.

test can written this: expect(callback.calls.mostrecent().args[1]()).toequal(object.create(null));, pass.

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.
