Structural pattern
From Wikipedia, the free encyclopedia
In Software Engineering, Structural Design Patterns are Design Patterns that ease the design by identifying a simple way to realize relationships between entities.
Examples of Structural Patterns include:
- Adapter pattern: 'adapts' one interface for a class into one that a client expects
- Aggregate pattern: a version of the Composite pattern with methods for aggregation of children
- Bridge pattern: decouple an abstraction from its implementation so that the two can vary independently
- Composite pattern: a tree structure of objects where every object has the same interface
- Decorator pattern: add additional functionality to a class at runtime where subclassing would result in an exponential rise of new classes
- Extensibility pattern: aka. Framework - hide complex code behind a simple interface
- Facade pattern: create a simplified interface of an existing interface to ease usage for common tasks
- Flyweight pattern: a high quantity of objects share a common properties object to save space
- Proxy pattern: a class functioning as an interface to another thing
- Pipes and filters: a chain of processes where the output of each process is the input of the next
- Private class data pattern: restrict accessor/mutator access
