Capture and restore an object's internal state without violating encapsulation. A behavioral design pattern for undo/redo.

Create new objects by copying existing ones. A creational design pattern for cloning and object duplication.

Provide a surrogate or placeholder for another object to control access to it. A structural design pattern for access control, lazy...

Retry an operation that has failed with transient errors, using configurable strategies like fixed delay, exponential backoff, or circuit...

Manage distributed transactions across multiple services by chaining local transactions with compensating actions for rollbacks. A...

Allow an object to alter its behavior when its internal state changes. A behavioral design pattern for finite state machines.

Define the skeleton of an algorithm in a base class, letting subclasses override specific steps without changing the algorithm's structure....
