javascript - Thorax 2.0.1 is throwing `Cannot read property '_thoraxBind' of undefined` when constructing my View -

with following thorax 2.0.1 code:

myview = thorax.view.extend({     events: {         'foo': 'bar'     },     template: 'hello world' });  foo = new myview();  foo.bar = function() {}

i getting following error when attempt create view:

here minimal reproduction.

why error occurring?

ps: can higher rep add thorax tag? thanks!

thorax requires events specified in events hash exist on object @ time of instantiation. there 2 possible solutions:

add function before object instantiation

// add 'bar' function object before instantiation myview = thorax.view.extend({     events: {         'foo': 'bar'     },     template: 'hello world' });  myview.prototype.bar = function() {}  foo = new myview();

use anonymous function wrap call

if dynamically adding function @ later time, can following:

// wrap call this.bar in anonymous function satisfy thorax myview = thorax.view.extend({     events: {         'foo': function(e) { this.bar(e); }     },     template: 'hello world' });  foo = new myview();  foo.bar = function() {}

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.
