When not to use the Command Design Pattern
- Simple Operations:
- For very simple operations or one-off tasks, introducing the Command Pattern might be overkill.
- It’s beneficial when you expect your operations to become more complex or when you need to support undo/redo.
- Tight Coupling is Acceptable:
- If the sender and receiver of a request are tightly coupled and changes in one do not affect the other, using the Command Pattern might introduce unnecessary complexity.
- Overhead is a Concern:
- In scenarios where performance and low overhead are critical factors, introducing the Command Pattern might add some level of indirection and, in turn, impact performance.
- Limited Use of Undo/Redo:
- If your application does not require undo/redo functionality and you do not anticipate needing to support such features in the future, the Command Pattern might be unnecessary complexity.
Command Design Pattern
The Command Design Pattern is a behavioral design pattern that turns a request into a stand-alone object, allowing parameterization of clients with different requests, queuing of requests, and support for undoable operations(action or a series of actions that can be reversed or undone in a system).
