Example text

Obviously, you do not want to change the architecture of ground floor (or existing floors). You may want to change the design of the architecture for the newly added floor without affecting the existing architecture for existing floor(s). Computer World Example Suppose in a GUI-based toolkit, we want to add some border properties. We can do this by inheritance. But it cannot be treated as the best solution because our user or client cannot have absolute control from the creation. The core of that choice is static there.

1. The number of objects are increased in the system. 2. Additional overhead is needed due to communication between the strategies and their contexts. 3. Users need to be fully aware of all kinds of possible behaviors to avoid confusion. 45 Chapter 8 Adapter Patterns GoF Definition: Convert the interface of a class into another interface that clients expect. The adapter pattern lets classes work together that couldn’t otherwise because of incompatible interfaces. Concept The core concept is best described by the examples given below.

The core concept applies when we want to add some specific functionalities to some specific object instead of to the whole class. Real-Life Example Suppose you already own a house. Now you have decided to add an additional floor. Obviously, you do not want to change the architecture of ground floor (or existing floors). You may want to change the design of the architecture for the newly added floor without affecting the existing architecture for existing floor(s). Computer World Example Suppose in a GUI-based toolkit, we want to add some border properties.
