instance

I'm learning to code and I have a question about some sample code I found: var Comment = new Schema({ user:userStub, time:Date, content: {type:String, required: true, trim:true} }); From what I learned about OOP, I thought the Comment object instance of Schema would be built like this: function Schema (user, time, content){ this.user = user; this.time = time; this.content = content; }; var Comment = new Schema (userStub, time, content); Anyone know the advantage of building the Comment instance via var Comment = new Schema({ instead? What does the ({ signify? Any help would be greatly

I have a JET Template that is meant to generate code for an interface implementation class. I am having trouble coming up with an executable test class that prints out this generated code because I am unable to get an object for the argument of the generate method created from the JET Template. I want the test class to work something like this: /** * An executable test class that prints out exemplary generator output * and demonstrates that the JET template does what it should. */ public class TestClass { public static void main(String args[]) throws ClassNotFoundException,

I've been searching for an answer to this for a while to no avail. First a bit of background: I'm trying to create an AI for robocode using Weka. I'm first logging the required data from a manual robot to an ARFF file, this is working as it should. This data is then processed this using Weka and a model created, I'm then saving this file. I can successfully import the model and classify a dataset that has been imported from another arff file and use the results. What I want to do now is every time the game status changes is assemble an instance and classify it, to decide for example which way

I know that this question has been answered before, but I can't seem to make any of the solutions work I'm making a ruby wrapper for an API that I need to call. The Interface class does all of the session handling and actual calling of the api, but I want to build helper classes for the functions that I will be performing most frequently. The problem I am having is that I need a way of maintaining one instance of the Interface class across multiple helper classes. Here's the code I have so far require_relative 'interface' module Api_Helper attr_accessor :xmlmc #get a new instance of the

I know that methods __repr__ and __str__ exist to give a formal and informal representation of class instances. But does an equivalent exist for class objects too, so that when the class object is printed, a nice representation of it could be shown? >>> class Foo: ... def __str__(self): ... return "instance of class Foo" ... >>> foo = Foo() >>> print foo instance of class Foo >>> print Foo __main__.Foo unutbu When you call print(foo) , foo 's __str__ method is called. __str__ is found in the class of foo , which is Foo . Similarly, when you call print(Foo) , Foo 's __str__ method is called. _

I wonder when Java Class is instance of Serializable. As I know class is serializable only if it implements Serializable interface. I'm trying to use junit to generate entity class (from some kind of template) and check if it is serializable. My generated class (which does NOT implement Serializable) looks like: package test; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Table; import javax.annotation.Generated; import javax.persistence.Id; @Entity @Table( name = MyTestTableDto.TABLE_NAME ) public class MyTestTableDto { public static final String
