One of the relational database management system class 10 questions and answers in the base class is a find method that returns instances stagic the child classes.

Since find is usually called as a static method, it needs to know the name of the child class. As you've found, this appears to be impossible to get in an easy fashion. This requires me to have a find method in every child class, but it does work. FYI: if you want to split your class into manageble chunks, what means different files for you, you can put you functoins into includes, and make include have a return value.

If mea have create a db object to collect the returned lines, you will be a little perplex when trying to call the result of this function. Good luck, Pascal. Hope that helps someone. The only possible explanation for this question seems to me u want to know the class before u instantiate the object. Well, this is of no use since u always instantiate a class of ur choice. This is all u need. Now u can differentiate according to which class the object belongs to.

Object is an instance of class B which is the child-class. You can use the function multiple times and also with class variables. As programmers, you're probably more organized than me, but, I do try and maintain some order in my classes and codes and separate them in "packages" as in java. This helped me keep them organized but caused havok when trying to use them, so what I did was to create a class that handles the loading of classes which I instanciate in all pages along with my error handling class all bundled up.

Hope this comes in handy Here's an example of satic diretory strucutre The loadClass would look like: loadClass "package1","name" ; Cute and easy. If anyone is interested in looking for a way to dynamically load existing objects into a class, here is what I found what is the most popular dating site in the uk useful. You can omit this if you want.

Hope this helps someone.
