I have the following entities: User Admin : Inherits User Rules (relation: Rules * <-> 1 User) I can access $user['Rules'] to get a Doctrine collection for Rules. However $admin['Rules'] does not return anything. (No error either, normally a Unknown related component 'Rules' error would be thrown. Any help would be greatly appreciate...
Hi, I am using NetBeans IDE 6.8 to create C++ project. While I use class inheritance, however, it seems to me that it does not recognize the derived class. Here is what I have: class A { public: A(vector<double> a, double b) {...} }; class B : public A { public: additionalfunction(...) {...} }; main() { vector<double> c = ...
I have class A that is supposed to inherit class B whose name is not yet known at the time of A being written. Is it possible to declare A not inheriting anything, and add B as the base class during A's instantiation? Example: First file class B: def __init__(self): self.__name = "Class B" def name(self): return self.__nam...
I have the following abstract classes: public abstract class AbSuperClass1<K,S> { //class definition } and: public abstract class AbSuperClass2<K,S> { public abstract <Q extends AbSuperClass1<K,S>> void method(Q arg); ... } I then have two concrete implementations public class Concrete1 extends AbSuperClass<String, Str...
This is probably a common Objective-C question reported by Java coders, but I don't know what to call it or how to search for the answer. Let's say I have a class and another class which extends it: AbstractModel @interface AbstractModel { } ModelImpl @interface ModelImpl : AbstractModel { } Separate from these, I have two more cl...
Why in the following code world is blue rather than red ? The specificity of .my_class is 0,0,1,0, but it inherits the color of #my_id which specificity is higher (0,1,0,0). HTML: <p id='my_id'> Hello <span class='my_class'> world </span> </p> CSS: #my_id { color: red; } .my_class { color: blue; } ...
How to configure Unity so that any class derived from some base class would go through injection pipeline defined for base class. public abstract class Base { public IDependency Dependency {get;set;} }; public class Derived1: Base { }; public class Derived2: Base { }; container.RegisterType<Base>(new InjectionProperty("Dependenc...
I'm trying to set up some stuff with Lua, but the specifics of Lua aren't important for my question. What I would like to be able to do is call a function, say OpenLib<T>(L), and have it get the table name for a particular class (as well as it's table) and register it with Lua. It essentially boils down to this: template <class T> sta...
Hi all, I'm having a problem when trying to compile these two classes (Army and General) in their own header files: #ifndef ARMY_H #define ARMY_H #include "definitions.h" #include "UnitBase.h" #include "UnitList.h" #include "General.h" class Army { public: Army(UnitList& list); ~Army(void); UnitBase& operator[](con...
I have an abstract class User and 2 classes which inherit from it, namely BEUser and FEUser. Information about all users (FEUser and BEUser) is stored in a single table. Does Doctrine allows this kind of mapping? Any examples? Also if doctrine supports it which object does the table class return (FEUser or BEUser)? Thank You ...
Hi, I must structure new model for application and I don't what is better: using inheritance or using enum as type of object: For example : Books class Book { public string Name {get;set;} public string Author {get;set;} public int NumberOfPages {get;set;} } public class Encyclopedie:Book { } public class Novel:Book { } or...
I am using "Class Table Inheritance - Using joined subclasses" as described here: http://www.castleproject.org/activerecord/documentation/trunk/usersguide/typehierarchy.html The following code is partly copied from there. [ActiveRecord("entity"), JoinedBase] public class Entity : ActiveRecordBase { ... private int id; [Pri...
I have created a subclass of a generic list so that I could implement a new interface public class CustomersCollection : List<Customer>, IEnumerable<SqlDataRecord> { ... } When I change the field definition to the new class (see example of old and new lines below) I get all sorts of compile errors on things that should exist in the o...
I want to do the following: class ErrorBase { public: void SetError(unsigned errorCode) { mErrorCode = errorCode; } char const* Explanation(unsigned errorCode) const { return errorExplanations[errorCode]; } private: char const* errorExplanations[]; unsigned mErrorCode; }; class MyErro...

Hi, to explain my problem, I'll give a simple example: My database has three tables: [positions] - position_id INT - position VARCHAR [employees] - employee_id INT - position_id INT - FK - name VARCHAR - birth_date DATE [vehicles] - vehicle_id INT - model VARCHAR - year VARCHAR - color VARCHAR The problem is that I must ...
I'm working on a tiny web library and wonder wheter I should call the HTTP handler methods for GET, POST, PUT etc. reflectivly or not. Fixed Methods First the variant with an if else ... block calling methods given in the base class where they have a default implementation returning an error to the client. Since a request to an unsuppo...
I have a class that extends a class that I need to overide, but I need to call that class's parent class. since I can't call super since that will execute the direct parent what is the best way to get the parent of my parent class? I am sure this is a basic question, but its been a while since I have been doing any java. class A { pub...
I'm not sure exactly how to describe this question, but here goes. I've got a class hierarchy of objects that are mapped in a SQLite database. I've already got all the non-trivial code written that communicates between the .NET objects and the database. I've got a base interface as follows: public interface IBackendObject { void Re...
When designing a derived class, are there [dis]advantages to adding a handler to a base class event in the ctor vs overriding the OnEventName() method and adding some behaviour (as well as calling the base method), if one doesn't need to change the base method and doesn't care in what order things happen, but only wants a reusable compon...
