Make the constructor of the object private so that it can't be instantiated
via new. Then add a static CreateObject() method that counts the number of objects created so fat and if exceeded throws an exception. This way the users of the object must call BrandNewObject=LimitedObject.CreateObject(); to have an instance and this way your CreateObject method can control the number of objects at large.

Hello, Dave!

DJ> if someone came accross this problem before it would be nice to explain DJ> how he\she solved this issue have fun!If I correctly understood the question: One of the solutions here will be object factory, that will track necessary objects count. Another one will be incrementing class static counter and if limit is exceeded throw exception in the constructor with appropriate message. -- Regards, Vadym Stetsyak www: http://vadmyst.blogspot.com |
