Structural Patterns

Structural patterns are a type of software design patterns focused on how classes and objects are composed to form larger structures. These patterns help ensure that if one part of a system changes, the entire system doesn't need to do the same, thereby promoting flexibility and efficiency in design. Key structural patterns include the Adapter (or Wrapper) pattern, which allows the interface of an existing class to be used as another interface; the Composite pattern, which composes objects into tree structures to represent part-whole hierarchies, allowing clients to treat individual objects and compositions uniformly; the Proxy pattern, which provides a surrogate or placeholder for another object to control access to it; the Flyweight, which reduces the cost of creating and manipulating a large number of similar objects; and the Bridge pattern, which separates an object’s abstraction from its implementation so that the two can vary independently. These patterns are crucial for creating flexible and efficient software architectures by wisely managing and composing objects and classes.
