Structural Design Patterns

Structural design patterns are concerned with the composition of classes or objects to form larger structures. These are the patterns comes under structural design patterns.

• Adapter pattern is used to provide a way for reusing an existing class.
• Bridge pattern is used to have interface and implementation independently in separate hierarchies.
• Composite pattern is used to handle primitive and composite objects uniformly.
• Decorator pattern is used to add additional responsibilities to an object dynamically.
• Facade pattern is used to provide simple interface to use an existing system in an easy way.
• Flyweight pattern is used to support sharing of objects when the objects are in large number with details to granularity of system.
• Proxy pattern is used to provide a place holder for an object to control its access.
