- * The object pool design pattern creates a set of objects that may be reused. When a new object is needed, it 
- * is requested from the pool. If a previously prepared object is available it is returned immediately, avoiding 
- * the instantiation cost. If no objects are present in the pool, a new item is created and returned. When the 
- * object has been used and is no longer needed, it is returned to the pool, allowing it to be used again in the 
- * future without repeating the computationally expensive instantiation process. It is important to note that 
- * once an object has been used and returned, existing references will become invalid.
