| 34 | <p> | |
| 35 | Using Pools gives you more control over how memory is used in your program. | |
| 36 | For example, you could have a situation where you want to allocate a bunch | |
| 37 | of small objects at one point, and then reach a point in your program where | |
| 38 | none of them are needed any more. Using pool interfaces, you can choose to | |
| 39 | run their destructors or just drop them off into oblivion; the pool interface | |
| 40 | will guarantee that there are no system memory leaks. | |

| 47 | <p> | |
| 48 | Pools are generally used when there is a lot of allocation and deallocation | |
| 49 | of small objects. Another common usage is the situation above, where many | |
| 50 | objects may be dropped out of memory. | |
| 51 | </p> | |
| 52 | <p> | |
| 53 | In general, use Pools when you need a more efficient way to do unusual memory | |
| 54 | control. | |
