Hands-On Design Patterns with Java

Understanding the stateless design pattern

When we implement the stateless design pattern, we create classes and objects that do not retain state changes. In this approach, each use of the object, as an example, uses the object in its organic form. In our context, state refers to the values of the object's variables. So, there is no definitive list of states. The state of an object is specific to a moment in time.

Implementing the stateless design pattern is appropriate for the following cases:

• When we want to clone services
• When the current state of an object dictates that object's behavior
• When object behavior is a runtime decision and that behavior is state-dependent
• When you want to process the state of an object as if it were an object ...
