an implementation for the type The following example illustrates how the factory could be converted into a Generic type: public class FactoryIMathematics< basetype> { public static IMathematics< basetype> Instantiate() { return new IntMathematicsImpl< basetype>(); } } The class FactoryIMathematics is converted into a Generic type, and the method Instantiate uses the Generic type, as does the class IntMathematicsImpl Following is the Generic type IntMathematicsImpl: internal class IntMathematicsImpl< basetype> : IMathematics< basetype> { public basetype Add( basetype param1, basetype param2) { checked { return param1 + param2; } } } The converted IntMathematicsImpl class is based entirely on using a Generic type In theory, it s possible to use any data type, and through the magic of Generics, it s possible to perform add operations on any type The problem is that it isn t possible to magically add any data type This is an example of abusing Generic types.

Reduce the privileges from the accounts that remain in the database to the absolute minimum necessary and reduce to only the privileges necessary to do the job that the accounts are designed for This means that every account in the database must have an owner, someone who uses that account or owns the business that uses it That physical person must have one account only; she must not share the account with other people, and of course the account must be used for one purpose only If an account is shared by people or shared among tasks, the account cannot have been designed for the specific purpose; this sharing implies that there would have to be a compromise After the removal of accounts has been completed and the reduction of privileges phase has simplified the users and their privileges, what is left must be locked and secured.

It s very easy to overuse Generics, as it s so tempting to define everything in abstract terms You might want to think that, once those abstract terms have been defined, magically plugging in a data type will result in a working system The problem is that it s impossible to do that Adding methods or properties to make the Generic types work is adding complexity Remember the focus of the Bridge pattern: to separate intention from implementation An intention can and needs to be described in abstract terms, but an implementation should be specific Another danger of attempting to define in abstract terms an addition is that adding integers isn t like adding complex numbers, floating-point numbers, or even different bases The result is that the different types share the same intention of adding, but their implementations will be entirely different..
