I am creating objects for a game, they are all sprites. but I also want them to implement an interface. Is it possible to do both ? If not, how can i have an object have the capabilities of a sprite and also have it implement an interface. I am wanting to create another class that checks all my objects to see what datatype they are and e...
I am making sims like game and right now I am trying to figure out how I will structure my objects. Right now I am thinking to create a class called GameObject, the psuedo is below public class GameObject { name:String width:int height:int } This way I could create objects like bushes, trees, and buildings. But...
Quick question. Does a class have to implement a interface directly to be accepted, or can it be a child of a parent class that implements it. so If I pass a child object into a method that only accepts IOBJECT, but the child class parent implements IOBJECT. will child object be accepted ? ...
I am creating a method that accepts a IOBJECT parameter. there is multiple class that implement this interface. I need to figure out which type IOBJECT is. how would i go about doing that ...
I am trying to figure out how to apply the is operand or the instanceof in a case statement to determine which datatype a interface object belongs too. keep getting errors switch (IOjbect is) { case Tile: trace ("Load Tile"); break; case House: trace ("A House Load...
I started my programming life not long ago. It is said that if you combine data and algorithm together, then you got a program. That is exactly what I do now, yet I hear these theories: Build for today, design for tomorrow Before coding, make each module as clear as possible Your code should not be understandable by just a handful o...
I am trying to use selective features of two classes into 3rd class. For example, I have Button1 class which creates a fancy button border and Button2 class which writes a the text in colorful format. Now these classes are provided to me by 3rd party vendors where i dont have access to the code. The classes are not sealed so i can inheri...
Hi, I have a python application which I cant edit its a black box from my point of view. The python application knows how to process text and return processed text. I have another application written in Java which knows how to collect non processed texts. Current state, the python app works in batch mode every x minutes. I want to make...
I am trying to design the interface that will be used internally for my application. Following Google's example, I strive to reduce public API clutter. However, there are some convenience methods that are defined in terms of the minimal methods. What factors should I consider as I seek a balance between convenience and tidiness? Google ...
Can we have a "not override a concrete method ..." compile time error when implementing interfaces ? An example to be more clear : I build up a framework containing interfaces. To use the framework developers need to implements some interfaces. But if they don't override equals(Object object) and hashCode() Object methods the internal ...
I have two methods that do essentially the same thing, just with different types. I want to abstract out this functionality to some generic method and I think I could do it easily in C# with delegates, but I don't know the equivalent in Java. I'm just showing two of the methods here, but there are several (like eight) different makeWha...
As I was advised by PMD, I want to reduce coopling by using interfaces instead of implementation ... In this case, knowing that I need a cloneable param, can I overcome the clone Dilemma (no clone() method in the Cloneable interface) ?? public MyConstructor(ArrayList<E> myParam) { this.myAttribute = (ArrayList<E>) myParam.clone(); ...
Hi The question is not only regarding the headline, but more of a "how will I achieve this, without trying to force a Java/Flash design into an Objective C (iPhone)program". I have 6 views that extends UIView, these views all have different behavior but share certain methods, like -(void) update and -(void) changeState:(NSInteger)state...
So I've spent some time thinking about this and been all over google looking for a 'solution' (the solution is most likely a matter of preference, but I'm unsure about this). Below is the problem I have, but the problem can be applied to a lot of situations regarding composition. I have a class, Colour, containing the members of red, gr...
I've been trying to sign an assembly and getting this error: 'Utils.Connection' does not implement interface member 'Interfaces.IConnection.BugFactory()'. 'Utils.Connection.BugFactory()' cannot implement 'Interfaces.IConnection.BugFactory()' because it does not have the matching return type of 'ThirdPartyLibrary.BugFactory'. That e...
This is a syntax question. I have a generic class which is inheriting from a generic base class and is applying a constraint to one of the type parameters. I also want the derived class to implement an interface. For the life of me, I cannot seem to figure out the correct syntax. This is what I have: DerivedFoo<T1,T2> : ParentFoo<T1, T...
Can I use interface method instead of delegate? How? I found searching that interface method is faster than using delegates. I would appreciate a simple code snippet. ...
I'd like to have a shortcut to create an implementation of an interface. Example: right click on an interface file, choose "implement", insert class name. Is there something like this in NetBeans (6.8)? ...
I understand that an interface in .Net defines a contract between the interface and a class that inherits it. Having just gotten done working on a project that made heavy use of an interface for the Data Access Layer, it got me thinking . . . whats the big deal? When I had to add a new method to the DAL, I had to create the method sign...
I am using Filehelpers to import my database from files. I am now working on the reverse process and am having trouble seeing how to create the records from my data objects. All the examples I can find show going from file -> table -> file I am using interfaces with generics to convert. I use this one on the inbound conversion: publi...
