When not to use the State Design Pattern

When to use the State Design Pattern

While the State pattern offers advantages, it’s not always the best solution. Here are some cases where it might be overkill:

Few states with simple behavior: If your object has only a few simple states with minimal behavioral differences, the overhead of the State pattern outweighs its benefits. In such cases, simpler conditional logic within the object itself might suffice.
Performance-critical scenarios: The pattern can introduce additional object creation and method calls, potentially impacting performance. If performance is paramount, a different approach might be more suitable.
Over-engineering simple problems: Don’t apply the pattern just for the sake of using a design pattern. If your logic is clear and maintainable without it, stick with the simpler solution.

Ultimately, the decision to use the State pattern depends on the specific context and complexity of your problem. Consider the trade-offs between code organization, maintainability, performance, and development effort before applying it.

State Design Pattern

The State design pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. It achieves this by encapsulating the object’s behavior within different state objects, and the object itself dynamically switches between these state objects depending on its current state.
