A structural pattern is a software design pattern that encapsulates relationships between entities.
Examples
Examples include:
Adapter pattern: Adapts one interface for a class into one that a client expects.
; Adapter pipeline: Use multiple adapters for debugging purposes.
; Retrofit Interface Pattern: An adapter used as a new interface for multiple classes at the same time.
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.
; Tombstone: An intermediate lookup object contains the real location of an object.
Composite pattern: A tree structure of objects where every object has the same interface.
Decorator pattern: Supports adding additional functionality to an object at runtime. Prevents issue where subclassing would result in an exponential rise of new classes.
Extensibility pattern: a.k.a. framework, Hides complex code behind a simple interface.
Facade pattern: Creates a simplified interface of an existing interface to ease usage for common tasks.
Flyweight pattern: A large quantity of objects share a common properties object to save space.
Marker interface pattern: An empty interface to associate metadata with a class.
Pipes and filters: A chain of processes where the output of each process is the input of the next.
Opaque pointer: A pointer to an undeclared or private type, to hide implementation details.
Proxy pattern: A class functioning as an interface to another thing.
