State
Description:
The State pattern allows an object to alter its behavior when its internal state changes
Benefits:
- Localizes state-specific behavior and partitions behavior for different states
- Makes state transitions explicit
When to use:
- An object’s behavior depends on its state, and it must change its behavior at run-time depending on that state.
- Operations have large, multipart conditional statements thatdepend on the object’s state.
